Title: Electronic control system and method for externally and directly controlling processes in a computer system

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to monitoring and control systems. More particularly, the present invention relates to an electronic monitoring and control system for externally monitoring processes in one or more computer systems. 
     BACKGROUND OF THE INVENTION 
     Over the past several years, the number of installed computer systems has increased. In addition, these computer systems are getting more and more complicated with many subsystems. Also, computer systems are being integrated with others across a room, in another building, and perhaps in another part of the country. This proliferation of computer systems has resulted in an increase in productivity of certain types of employees, but at the same time it has created a need for many new employees. In particular, new computer technicians have been hired to monitor and repair the new computer systems. To help aid in the monitoring process many of these computer systems include an operating console which is displayed on a video display. The operating console shows the status of various system components like disk drives, chillers, data communication lines, etc. 
     A need exists for a way to consolidate all of these monitoring activities into a single site. For example, eight operating consoles could be consolidated into one monitoring device which would reduce the need for employees who perform monitoring operations by 8 to 1. 
     In addition, a need exists for automating some of the routine control situations like restarting a computer system, calling a repair or service representative, and rerouting data communication links. Such automation has been done in the past by adding additional hardware and software agents or processes which run on the computer system being monitored. The disadvantage of such approaches are that they are inflexible to changes made to the underlying computer system. For example, if a controller board is added to a mainframe computer and then that system is updated to a new data bus type, the old controller board is no longer useful. Similarly, when software agents are run on the computer system to be monitored, they must be tailored to the operating system being run on the computer system and must be tested to determine whether they interfere with other software or processes which are to be run on the computer system. 
     A better solution to this monitoring and control problem would be to find a way to perform these operations without adding hardware or software to the computer system to be monitored. The present invention provides a solution to this and other problems, and offers other advantages over the prior art. 
     SUMMARY OF THE INVENTION 
     An electronic control method for externally controlling processes in the computer system is provided in which electronic data is presented as graphical information to a user on a display device. In addition, electronic data input by the user is received. Processing rules are obtained from user input provided through the input device in response to processing rules displayed to the user on the display device. Operations of the computer system are controlled based on the processing rules with the electronic data processor such that the computer system can be automatically externally and directly controlled with the processing rules by only utilizing preexisting computer system signals received from the computer system and control signals sent to the computer system. In addition, a control system for implementing the external control method is provided. 
     These and various other features as well as advantages which characterize the present invention will be apparent upon reading of the following detailed description and review of the associated drawings.

     DETAILED DESCRIPTION 
     A preferred embodiment of the present invention is an Intelligent Console System (ICS) 100 which is shown in FIG. 1. The ICS 100 is designed for the primary purpose of automating operations--monitoring, operating, and alerting of all processes performed or observed. This includes mainframe startup (power on, IML, IPL, etc.), mainframe shutdown (OS shutdown, CPU power off, etc.), operational monitoring and controlling of the complex (scanning and alerting of messages and signals, responding to operational processing, initiating recovery responses, etc.), and operational consolidation (multiple data centers or servers monitored and controlled from a single location). 
     The ICS 100 is entirely outboard--there are no invasive &#34;hooks&#34; to any of the host environments. Not only does this approach make installation simple and fast, but expensive host CPU time is not used by the ICS 100 monitoring and automation routines. 
     FIG. 1 illustrates an example of a preferred embodiment ICS 100 installation. It will be appreciated by those skilled in the art that the interface types and quantity of ICS components depend on each installation and as such the particular arrangement described below is for illustrative purposes only. 
     The ICS rack 100 houses the main processing components--central processing unit (CPU) case, Universal Service Bus unit (USB), and power distribution unit (PDU). The CPU case includes a hot-swappable redundant power supply, hard disk, tape drive, UNIX operating system, and the ICS software. Each USB unit has a 15 slot capacity for interface cards. One slot is used for the interface to the ICS CPU and the other 14 slots house the connectivity interface cards. 
     The Power Distribution Unit (PDU) 140 protects the ICS equipment 100 with its built in circuit breakers. Also, it provides a convenient centralized power source for the ICS components from the customer site (i.e.,. a single 30 A 110V power feed). 
     The ICS system console 142 preferably is a UNIX VT100 terminal interface and keyboard. It is used for starting up and shutting down the ICS 100 (and UNIX) and other administrative activities. It connects to the CPU case via a RS232C interface. 
     The ICS user console 144 is the Xterminal: a large monitor (utilizing a graphical user interface), 3270 keyboard, and mouse. It is the user interface to the ICS 100. It connects to the CPU case via a small Ethernet (IEEE802.3) TCP/IP network. 
     The ICS printer 146 is used for printing ICS logs and scripts. It connects to the CPU case via a small Ethernet (IEEE802.3) TCP/IP network. 
     The ICS digital input (DI) unit 148 is the interface for monitoring warning signals from air conditioners, chillers, water leak sensors, and other equipment with digital interfaces. Each DI unit 148 has an 8 device capacity. A maximum of 16 DI units can be connected to one ICS 100. 
     It connects to the USB via fiber optic cable, which provides for high interference tolerance and approximately a one mile range. The physical placement of DI units is flexible--normally placed under the raised floor near the equipment connected to it. 
     The ICS digital output (DO) unit 150 is the interface for controlling air conditioners, chillers, warning lights, and other equipment with digital interfaces. Each DO unit 150 has an 8 device capacity. A maximum of 16 DO units can be connected to one ICS 100. 
     It connects to the USB via fiber optic cable, which provides for high interference tolerance and approximately a one mile range. The physical placement of DO units is flexible--normally placed under the raised floor near the equipment connected to it. 
     The ICS power unit 140 is the interface for controlling the power source of mainframe CPUs. Each unit controls one CPU. A maximum of 4 power units can be connected to one ICS 100. 
     It connects to the USB via fiber optic cable, which provides for high interference tolerance and approximately a one mile range. The physical placement of power units is flexible--normally placed under the raised floor near the CPU or CPU control device. 
     The ICS sensor unit (not shown) has temperature and humidity sensors for monitoring the temperature and humidity at the location the sensor unit is placed. A maximum of 4 sensor units can be connected to one ICS 100. It connects to the USB via fiber optic cable, which provides for high interference tolerance and approximately a one mile range. The physical placement of sensor units is flexible--normally placed near a CPU. 
     The ICS warning light 152 is for alerting support staff that the ICS 100 needs attention. The required attention is generally for a detected problem situation. In operation, the warning light 152 flashes and produces an alarm sound. This type of alerting allows the ICS 100 to operate unattended--no baby-sitting required--and support staff is alerted when attention is needed. It connects to a DO unit 150. The physical placement of the warning light 152 should be near support staff. 
     Referring now to FIG. 2, a system 100 is shown capable of performing the automated control operation of the preferred embodiment intelligent console system (ICS) 100 shown in FIG. 1. The preferred embodiment of the present invention is preferably practiced in the context of an operating system resident on a workstation or personal computer such as the Sun Microsystems® Sparc Station®, IBM® PS/2® or Apple® Macintosh® computer. A representative hardware environment is depicted in FIG. 2, which illustrates a typical hardware configuration of a workstation in accordance with the preferred embodiment having a central processing unit 110, such as a microprocessor, and a number of other units interconnected via a system bus 112. The workstation shown in FIG. 2 includes a Random Access Memory (RAM) 114, Read Only Memory (ROM) 116, an I/O adapter 118 for connecting peripheral devices such as disk storage units 120 to the bus 112, a user interface adapter 122 for connecting a keyboard 124, a mouse 126, a speaker 128, a microphone 132, and/or other user interface devices such as a touch pad or touch screen (not shown) to the bus 112, communication adapter 134 for connecting the workstation to a communication network (e.g., a data processing network) and a display adapter 136 for connecting the bus 112 to a display device 138. The workstation typically has resident thereon an operating system such as UNIX® or the Microsoft® Windows NT operating system. 
     To implement a high-level user interface, the Intelligent Console System, referred to as &#34;ICS&#34; 100 throughout this description, a UNIX window system (X-Windows with a Motif interface) is used. A pointing device called a &#34;mouse&#34; is used to manipulate objects in windows on the screen and perform basic operations. The ICS system uses a separate window for each function. Almost all operations can be controlled using the mouse. 
     Each window shown on the display can be divided into. a client region, used for entering and displaying data through graphics or with key input, and a window function region on the periphery, used to control the window. 
     How to start the ICS will now be discussed. 
     First, switch on power to the ICS. Boot the OSF/1 system by typing the word &#34;boot&#34; on the ICS system console and pressing the Enter key. If the startup procedure is successful, a login prompt will appear on the ICS system console. Switch on power to the ICS user console. The ICS Start Session screen will be displayed on the user console. Move the mouse cursor over the login text-entry box and click on it. Type in a login name and press the Enter key. Type in the password and press the Enter key or click on the OK button. If the login name and password are valid, the ICS system should start. 
     Once the ICS session is running, an ICS system screen will be displayed on the ICS user console, as shown in FIG. 3. 
     This screen displays the status of the data center environment, CPU, and the operating system. This screen also displays messages coming from the operating system. 
     The ICS session allows the user to open several windows at the same time. This provides quick access to informational and control screens for all the systems connected to the ICS. Note that while several windows can be displayed at the same time, commands can be entered only in the &#34;active&#34; window. 
     If an operator without appropriate authority tries to open a protected window, a message will be displayed stating that the operator does not have authority to operate the window. 
     The basic windows available and their operations will now be discussed. The ICS Main (or system root) Window allows the screen operation mode to be changed and the ICS system to be shut down. 
     The ICS Execution Log Display, as shown in FIG. 4, (called the ICS log window throughout) displays the ICS system execution log (this is not the user system log). This window allows the operator to reference the ICS system log. To display previous messages, click on the up arrow on the vertical scroll bar. This window also allows the user to print the ICS system log. To do this, click on the Print button on the Select menu. The Filtered Message Display (called the System message window), shown in FIG. 6, displays the user operating system message log. These messages are selected or modified by the message filter. Operator comments will be displayed with the system messages. The user can refer to the system filtered message log by clicking on the vertical scroll bar. Click on the up arrow to see earlier messages. 
     To display the Icon Control window, FIG. 8, double click on the Icon Control button. This window allows the user to put a specific message into the system log. The buttons on this screen perform the following functions. The Color Box allows selection of the color of the message being entered into the log. The ICS session uses different colors to indicate the priority of a message. The Message Box allows the operator to add messages to the system message log. The Operator name Box allows the operator to type in a name up to eight characters long. The Log comment Box allows the operator to add a comment to the system message log. This message is displayed on the Filtered Message Display, FIG. 6. The comment may be up to 50 characters long. When a special log message has been typed in, save the message in the log by clicking on the &#34;OK&#34; button. To return to the previous window without saving any entries, click on the &#34;Cancel&#34; button. 
     The System Status Summary window, shown in FIG. 9, (called the System Summary window) displays the status of the data center, hardware, or operating system and I/O box signal. Information is displayed in specific colors to indicate the status, such as the room, CPU, and operating system status. To display a window with detailed information on the specified room, CPU, or operating system, double click on the appropriate button. 
     The Room button displays information about the data center environment in specific colors. The data comes from the ICS I/O boxes. Double clicking on this button will display the Room Selection menu, FIG. 11. The ICS operator can open the Schedule, Script, Configuration, and I/O management windows from this menu. 
     The CPU button of FIG. 9 displays the CPU condition in specific colors. Depending on the display mode, double clicking on this button will display a window with the following choices. In special extension mode, the ICS system log window is displayed. In normal extension mode, the H/W configuration window is displayed. In non extension mode, the Emulator window (system console) is displayed. 
     The OS button of FIG. 9 displays operating system conditions in specific colors and with specific messages. Depending on the display mode, double clicking on this button will display a window with the following choices. In special extension mode, the ICS system log window is displayed. In normal extension mode, the H/W configuration window is displayed. In non extension mode, the Emulator window (system console) is displayed. 
     The Application Summary window displays the operating system and application status. The Application program execution status window displays the operating system status in specific colors and with specific messages. To display-the S/W Configuration window, double click on the OS button, titled &#34;Tokyo CiRCLE HeadQuat Normal.&#34; This window displays the status of running application programs. 
     The Display Emulator window (called the Emulator window) allows the ICS operator to operate all consoles that are connected to the ICS. To display the function key template, click on the SoftKey button on the Select menu. 
     The Emulator Selection window displays all consoles managed by the ICS. To display the Console Emulation window, double click on the console icon. 
     All of the basic ICS windows are displayed as icons in this window, shown in FIG. 13. To view a specific window, double click on the appropriate icon. 
     The Console window, called the UNIX Console Window, provides an area in which the operator can enter UNIX commands. This window is used for system maintenance, not standard ICS operation. 
     The Editor window is a screen editor for the Schedule file, the Script file, and the Configuration file. 
     To display the User-Defined Message window, double click on the message line of the Emulator window. A window as shown in FIG. 7 is displayed. These messages are defined in the User Message file. 
     Now the editing of schedules on the ICS will be discussed. There are four types of files used to manage schedules on the ICS: Daily schedule file, Weekly schedule files, Specific-day files, and Holiday file. To display the Room Selection window, FIG. 11, double click on the Room button on the System Summary window, FIG. 9. To display the Edit Schedule window, click on the Edit Schedule button on the Room Selection window. A screen as shown in FIG. 15 will appear. The holiday file schedule has a higher priority than weekly and daily schedules, but if holiday data and specific-day data are found for the same day, then the ICS will use the specific-day schedule instead of the holiday schedule. The daily schedule may use one of three ranges: Monday to Friday (5 days), Monday to Saturday (6 days), or Monday to Sunday (7 days). This range is determined at installation time and cannot be changed by the ICS operator. To print the schedule summary, double click the Print button on the File menu. The ICS operator can alter the schedule by using the Cut Schedule, Copy Schedule, and Paste Schedule functions. 
     When editing a schedule, the Display contents window, FIG. 16, shows the following scripts and their associated start times: Room-preparation scripts, room-shutdown scripts, CPU IMPL script, CPU shutdown script, OS IPL script, OS shutdown script, Subsystem startup script, and subsystem shutdown script. When scripts have the same start time, the priority used is: Room, then CPU, then OS, then Subsystem. 
     Now the management of the various scripts will be discussed. For example, the Room Selection window, FIG. 11, is accessed by a double click on the Room button on the System Summary window, FIG. 9. To display the Edit Script window, click on the Edit Script button on the Room Selection window. All of the script source files (which have the file name extension of scr) will be displayed on the Open File window. To select a file, move up and down through the list using the vertical scroll bar. After selecting the Script File Name line, click the Open button. Then display the Edit window. Clicking on the Cancel button, the Edit window allows the user to create files. 
     Also from the Room selection window, to display the Script Management window, FIG. 10, click on the Script Management button. These are displayed for each initiator: Initiator number, Execution class/Target class (Room, CPU, or OS), Script name, Execution status, Wait time in script. Use the vertical scroll bar to move up and down the list of options. Control the executing script by selecting one of the initiator lines and clicking one of these action buttons: pause, resume, skip or cancel execution. The ICS will prompt the user to confirm the change being requested. To confirm the change, click on the YES button. To cancel the request and return to the previous window, click on the NO button. To return to the previous window, click on the Close button. 
     To display the Script Execution window, FIG. 17, click on the Exec button on the File Menu on the Script Management window. All of the script object files (which have the file name extension of scx) will be displayed. Select an object file by double clicking on the line containing the file&#39;s name. Move up and down through the list of files by using the vertical scroll bar. Start script execution by clicking on the Exec button. Then close this window. Return to the previous window by clicking on the Cancel button or select the Close button from the menu. 
     Now the control and observation of the hardware environment will be discussed, starting with the CPU configuration. The hardware status and start control operation can be checked from the hardware connection figure window. To display the H/W Configuration window, FIG. 19, double click on the CPU button on the System Summary window, FIG. 9. 
     There are six buttons on the H/W Configuration Window, FIG. 19. Each button displays the operational status. If anything unusual happens, the appropriate button will change color. The top button displays the status of the CPU (for example, &#34;Tokyo 9021 normal&#34;). The middle button displays the status of the CPU channel. The bottom four buttons display the status of the I/O units (DASD, Tape, Printer and Miscellaneous). These screen relations are in &#34;Normal Extension&#34; mode. In the other modes, the screen relation will be different. In &#34;Not Extension&#34; mode , if the top button is clicked, the Emulator window will be displayed. In &#34;Express Extension&#34; mode , if the top button is clicked, the CPU log window will be displayed. To change the color or name of a button, click on the desired button. Click on the Select Icon menu. Then display the Icon Control window. The operator will be able to change the color or name from this window. 
     To check the CPU error log when an event occurs, display the CPU Log window by double clicking on the top button of the H/W configuration window, FIG. 19. Then, double click one of the message lines to display the user-defined message. If a user message is not defined, a warning message will be displayed. If the ICS is being run in Express Extension mode, the operator can display the log window for the specified CPU either by clicking on the CPU button on the System Summary window or on the top button on the H/W Configuration window. 
     The Channel Configuration, FIG. 20, is used to check the status of I/O Channel or I/O units. To bring up the Channel Configuration window, double click the middle button on the configuration window. CHPID numbers and Connected I/O units are displayed on this window. If the status is not normal, change the color. 
     To check the I/O channel error messages log, display the Channel Log window by double clicking on the channel number button on Channel Configuration window. There is a log of &#34;Priority messages&#34; and &#34;I/O error messages.&#34; Display the user-defined message by double clicking on one of the message lines. If a user message is not defined, a warning message will be displayed. 
     The operator can check the status of an I/O unit by displaying the I/O Configuration window, FIG. 5. Double click on the I/O Unit button on the H/W Configuration window, FIG. 19. The operator also may double click on the I/O Unit button on the Channel Configuration window, FIG. 20. However, this method will display data for only one channel. The I/O address, I/O device type, and Volume Name are displayed. If the status of a device is not normal, the color will change. 
     To check the I/O unit error messages log, the user displays the I/O unit error log window by double clicking on the I/O Unit button in the I/O Configuration Window, FIG. 5. A log of I/O error messages is shown. To display the user-defined message, double click on a message line. If a user message is not defined, a warning message will be displayed. 
     It is possible to observe the execution status of the mainframe operating system for each CPU. The color of the icon will indicate the status of the Operating System. Open the Application Summary Window by double clicking on the Application Summary Icon in the Icon window, FIG. 13. To display details of the software configuration by displaying the S/W configuration window, double click on the desired line. 
     The operator may also check the execution status of subsystems in each Operating System. The icon color indicates the status of the subsystem. To open the S/W Configuration Window, double click on the Operating System button on the Application Summary window. The top line displays the name of Operating System (PROD) and its status (Normal). The other lines denote subsystems running under the Operating System (for example, VTAMP1, CICSP1, and DB2P1). If a status changes, the color also will change. The operator can also display the S/W Configuration window by clicking on the OS button on the System Summary window. To check the execution log of the Subsystem for each Operating System, open the S/W Log Window by double clicking on the Subsystem button on the S/W Configuration window. The error history of the subsystem is displayed. 
     The present invention also allows for observation and control of environmental devices. For example, the operator can check the status of CPU power (on or off) and control CPU power remotely. First, the user opens the Room Selection Menu, FIG. 11, by double clicking on the Room button on the System Summary Window, FIG. 9. Then open the I/O Management Window, FIG. 12, by clicking on the I/O Management button on the Room Selection Menu, FIG. 11. Next, open the Power Box window by clicking on the Power Box button on the I/O Management Menu window, FIG. 12. If the &#34;On Action&#34; button is green, CPU power is on. If the &#34;Off Action&#34; button is red , CPU power is off. If both buttons are colored, then the CPU is still powering up. To display the confirmation window, click on the &#34;Action Button.&#34; To start the power operation sequence, click on the YES button. To cancel the previously- selected operation, click on the NO button. Click on the Close button on the Power Box window to close the Power Box window. 
     The Control Data Center equipment is connected to a D/O box. To observe and control this equipment, open the Room Selection Menu, FIG. 11, by double clicking on the Room button on the System Summary Window, FIG. 9. Open the I/O Management Window, FIG. 12, by clicking on the I/O Management button on the Room Selection Menu, FIG. 11. Open the D/O Box window, FIG. 18, and display the I/O Management Menu window by clicking on the D/O Box button. To display the status of a piece of equipment, click on the desired line. Its status will be displayed in the selection box. 
     To check the status of Data Center equipment connected to the D/I box, open the Room Selection Menu, FIG. 11, by double clicking on the Room button on the System Summary Window. Then open the I/O Management Window by clicking on the I/O Management button on the Room Selection Menu. Open the D/I Box window by clicking on the D/I Box button on the I/O Management Menu window. 
     It is also possible to check the Data Center temperature and humidity. This information is gathered from the sensor box. Open the Room Selection Menu by double clicking on the Room button on the System Summary Window. Open the I/O Management Window by clicking on the I/O Management button on the Room Selection Menu. Then open the Sensor Box window by clicking on the Sensor button on the I/O Management Menu window.) The temperature and humidity measured are displayed at the sensor box. Temperatures can be displayed in degrees Fahrenheit or Celsius. 
     As noted above, the ICS 100 is capable of automating the monitoring, operating, and alerting of all processes performed or observed in the data center. Because the ICS 100 can automatically process up to several thousand messages per second, it does not miss messages. Additionally, the ICS 100 can monitor multiple consoles (i.e., screen outputs from tasks or processes executing on a mainframe computer) at the same time with the same accuracy as monitoring only one console. 
     Normally, a user/operator manually controls the system IPL, operations, and shutdown by interacting with the system console 142 and an operating system (OS) console. All of the operations, such as entering commands, monitoring for special messages, and entering responses are based on some set of rules. These rules can be explicitly written as a detailed set of procedures. Each procedure can be written as one or more ICS scripts. 
     Procedures that were traditionally performed manually can be automated on the ICS 100 by use of these scripts. Designing scripts for automatic operation can begin by creating detailed documentation of the repetitive operations performed by the operator. ICS scripts can then be written to automatically perform the steps defined in the documentation. 
     Automation is accomplished through the use of steps stored in scripts. Script files are created using the ICS 100 script editor and are written in the ICS script language. This script language has been specifically designed for monitoring and control environments. The script language is a powerful, flexible, easy to use programming language similar to other structured, high- level programming languages such as BASIC. 
     After saving a script source from within the script editor, the script is automatically compiled into a form that can be executed on the ICS 100; this form is called a &#34;script object&#34;. In the preferred embodiment, the script sources and objects are stored as UNIX files in the ICS system 100. 
     A source script can be comprised of several different steps: 
     *STEP1: 
     TURN ON AIR CONDITIONERS, CHILLER, AND CPU POWER 
     *STEP2: 
     CPU IML RESET 
     *STEP3: 
     LOAD OS 
     *STEP4: 
     BOOT SUBSYSTEM 
     Script lines such as &#34;STEP1&#34; are called &#34;labels&#34; or &#34;label statements&#34;. Labels help make the script source easier to read and, most importantly, are used as reference points for script logic control. Labels generally define a cohesive set of commands that are always executed together. As a reference point, a label is used for branch execution or a &#34;go to&#34; --an immediate transfer of script execution to the reference point. A go to can be made to any step within the current script. 
     Certain script names are reserved as special--they are automatically executed when a status change in the digital-input, digital output, sensor, or power units is detected. The reserved scripts enable automatic customized response to status changes. The ICS attempts to execute the appropriate reserved script when necessary. If a reserved script to be executed does not exist, nothing happens--no error occurs.

     Reserved scripts must be written by the user/operator due to their customized nature (very simple reserved scripts typically are supplied that only display informational messages--no corrective action is taken). For example, the &#34;#snserrs.scr&#34; is executed when either the temperature or humidity sensor limit is exceeded. This script may contain instructions to start up the backup air conditioner and send a message to the pager of the person responsible for maintaining the air conditioners. The actions and depth of automated response is entirely decided by the user/operator. 
     There are four ways to execute a script as noted in Tables 2 and 3. 
     
                       TABLE 2

        Add a script to the schedule to execute on a certain              
        date/day and time or to execute on reoccurring intervals.         
Immediate:                                                                
         Select a script for immediate execution.                         
Script:     An executing script can initiate the execution of another     
        script.

          Automatic execution of special scripts is triggered by          
        digital input, digital output, sensor, or power unit status       
        changes.

     The syntax for one script executing another script deserves special attention. The syntax (and the &#34;rules&#34;) for calling/executing another script from within a script is the same as for calling a built in command. For example, the built in HEXSTR command requires one parameter--a number--and has a return value of a string. The format in a script will look something like this: 
     $HexNum := HEXSTR(15) 
     If a script was named MYSCRIPT and accepted one parameter--a number--and had a return value of a string, the format for calling MYSCRIPT from within another script will look something like: 
     $RetVal := MYSCRIPT(42) 
     Turning now to script organization, the concept of a &#34;master script&#34; which is a &#34;big looping&#34; procedure preferably is used. This &#34;master script&#34; reads the next message, checks if it needs processing and initiates any needed procedure(s)/action, and begins again by reading the next new message. 
     A master script will contain a READMSG statement to retrieve the next message. Next, a SWITCH statement is used to perform the initial check to see if it requires processing. If the message requires additional processing (a CASE statement evaluates TRUE), the commands in the CASE statement of the SWITCH command first do any additional checking of the message needed and second call another script to process the message. 
     In most other ways the script language follows the organization and structure of typically second and third generation programming languages like Fortran or &#34;c&#34;. In particular the syntax, handling of variables and arrays, string expressions, mathematical expressions and the like are substantially similar to those typically found in other higher level programming languages. 
     Several intrinsic manifest constants preferably are predefined in order to make scripts easier to read, write, and maintain. The constants can be used anywhere in a script--they are equivalent to the value they represent. For example, instead of using: QUEUE(1). The following is more clear: QUEUE(ON). 
     Additionally, even though the following is a valid numeric expression, it is not the true intention for the use of manifest constants: 
     %Num := TRUE +1 //%Num would contain 2 
     Some possible intrinsic manifest constants are listed below in Table 4.

     In the context of the script language a port number refers to a logical number assigned to each &#34;ICS to customer equipment&#34; interface. The port numbers are defined in a configuration file at installation time. Each interface-type (coax, DI, DO, power, sensor, modem) has its own sequence of unique port numbers. Each interface-type command pertains to only one type of interface. 
     The ICS Object Manager is an extensible facility that encompasses object definition and manipulation across the entire ICS system 100. The objects are a flexible way for the user/operator to create and manage real-world operations in the ICS 100. Since installations and operations vary per customer, the ICS object manager enables each operator to define specific customized routines. The object manager provides the framework and the operator provides the definitions. 
     Each object is created or defined by its &#34;type&#34; definition (the object type). The object manager contains two types: default and custom. Default types are those inherent to the system and custom types are those created by the operator. The object manager&#39;s openness enables the operator to modify default types and to define their own types for use in various functions of the ICS 100. 
     Each type has one or more attributes (e.g., name, colors, and fields). The attributes are defined and initialized in the ICS configuration files and the values are set and read with script commands. Object manager script commands all begin with the prefix &#34;OBJ&#34;. 
     Object type refers to the &#34;map&#34; or the definition of an object type. Each type has a name and is referred to by its name. The type definition contains the information to define the type to the object manager. The &#34;type&#34; parameter for the object manager script commands is a string and is the type name. 
     Object Name is the name of an object. In object-oriented terms, the object itself is an instance of the type. Each instance will have a unique name--the object name. The basic syntax rules for object names are: 
     Cannot contain a colon 
     Object name in the CPU class must be unique per ICS 
     Object name in the OS class must be unique per CPU 
     Object name in the SW class must be unique per OS 
     Object name in the UNIT class must be unique per CPU 
     In addition, each object has a &#34;hierarchical&#34; key, referred to as the object key. This key is a string expression that specifies a precise object by referring to the chain of object names. Only one script command uses the object key--OBJID. The rest of the commands utilize the object id. The syntax rules require that each object name must be separated by colons. For example, Full syntax: &#34;CPU:OS:SW&#34; or &#34;CPU:UNIT:??&#34;. 
     Object ID is the unique id for each object. The advantages of using object Ids include speed of execution, reduced script maintenance issues, and ease of implementation. 
     A script executes in a class on an object. Each object is also represented by an icon displayed on a window, such as the System Summary or CPU Configuration window. Table 5 shows some of the icon class constants.

     Each icon in a class has a unique name referred to as the &#34;Icon Name&#34;. This name is displayed on the icon and is used in some script commands. The icon name is used to uniquely identify an icon in a class. The icon classes are pre-defined, but icon names are user defined. Some examples of icon names are 3090, 9021, CPU #1, MVS #3, and Sys5. Icon name and icon class are both optional arguments. However, if the icon name is specified, then the icon class is required. If class and name are both omitted on a relevant script command, then the icon affected defaults to the one the script is executing on. 
     The default class and name for a script are determined when the script begins executing: 
     A script started from another script defaults to the class and name of the calling script and, where applicable, can use parameters to override the defaults. 
     A scheduled script&#39;s class and name are set by its definition in the scheduler. 
     An immediately executed script&#39;s class and name are set by the user in the script execution window. 
     A reserved script&#39;s class and name are special, and are set by the system. 
     In a script executing on a lower-level class (any class below ROOM), when a higher-level icon class is specified without the icon name, the icon affected is the icon in the specified class that is an ascendant of the script&#39;s class. In a script executing on a higher-level class, when a lower-level icon class is specified without the icon name, the icon affected is all icons in the specified class. 
     The following set of Tables provide list of script commands organized by type. The commands shown in Table 6 are used for manipulating files.

     The functionality of most of these script commands is readily apparent from the brief description given in the above tables and is otherwise well known in the software programming language art. However, some of these script commands have been specifically developed for use in the monitoring and control environment from which the present invention was developed. As such, these commands may be unfamiliar to those of ordinary skill in the art of software programming. A brief discussion of these monitoring and control specific script language commands is given in the following portion of the detailed description. 
     AICONNAMES 
     This command fills an array with all of the icon names in a class. An associative string array is created with its index keys being the names of the icons in the specified class. The set of icons obtained for the specified class is determined by the ParentIcon parm. Not all icons in the specified class are obtained, only the icons whose parent icon name is ParentIcon. In the preferred embodiment, the ParentIcon parm is ignored for class of CPU. 
     The syntax for the command is: 
     AICONNAMES ($AssocArray, Class, ParentIcon) 
     where, 
     
         ______________________________________                                    
$AssocArray  Associative string array variable. The                       
             associative array to receive the icon names                  
                                  as its keys. Each icon name becomes an  
             index key in the array. The data for each                    
             element remains at the itia1ization state                    
empty string &#34;&#34;.                                                          
Class                   Numeric expression. The icon class.

     BLOCKSCAN 
     This command enables up to 256 SCANB commands to execute as a group. BLOCKSCAN delineates the beginning and ENDBLOCK delineates the ending of a group of SCANB commands to execute as a group. The SCANB commands are executed simultaneously and script execution continues with the branching logic of the first SCANB command that fulfills its own scanning condition. If the Wait time expires, script execution branches to the label specified by the *Timeout parm. 
     The syntax for the command is: 
     BLOCKSCAN (Wait, *Timeout {, $Array}) . . . ENDBLOCK 
     where, 
     
         ______________________________________                                    
Wait      Numeric expression. The number of seconds                       
          to wait before timing out when none of the                      
          SCANB commands are successful. This number                      
          specifies how long the command waits for                        
                             the scans to be successful.                  
*Timeout         Label literal. The label to jump to when                 
          the Wait time expires.                                          
$Array           Normal string array. Optional. The array                 
          to populate with subexpression results, if                      
          any, from the Text parm in a SCANB command.                     
          Each array element will contain one                             
                           subexpression result - element one will        
          hold the result for subexpression one,                          
          element two will hold the result for                            
          subexpression two, etc. The subexpressions                      
          are &#34;numbered&#34; from left to right in the                        
                          Text parm. $Array is only populated when        
          the Text parm contains subexpressions and                       
          the scan text is found.

     DIUNIT 
     This command checks the status of a device connected to a DI unit. The command sets the value of the specified variable to the status of the DI unit connected to the specified port. 
     The syntax for the command is: 
     DIUNIT(Port) ==&gt; %Status 
     where, 
     
         ______________________________________                                    
Port       Numeric expression. This parameter refers                      
           to the assigned DI port number to which the                    
                              device is connected.                        
______________________________________                                    
 
    
     This command returns a numeric value. The value of the DI status--either 0 or 1. 0 implies OFF and 1 implies ON. However, depending on the type of connected device, the values can have other meanings. An example of how to use this command is shown in Table 16. 
     
                       TABLE 16

     DOUNIT 
     This command controls the device connected to a DO unit. The switch on the specified DO unit port is opened or closed, thereby changing the status of the connected equipment. This effectively switches the equipment ON and OFF. 
     The syntax for the command is: 
     DOUNIT(Port{, Operation}) ==&gt; %DOSwitch 
     where, 
     
         ______________________________________                                    
Port        Numeric expression. The assigned power                        
                                  port number to which the CPU is         
            connected.                                                    
Operation        Numeric expression. Optional. ON closes                  
            the switch and OFF opens the switch. If                       
            not specified, the DO switch setting                          
            remains the same.                                             
______________________________________                                    
 
    
     This command returns a numeric value. The setting of the DO switch is returned (not the current status of the device connected to the DO unit--use DIUNIT for that). If the Operation parm is specified, the return value is the old DO switch setting value. If the Operation parm is not specified, the return value is the current DO switch setting value. An example of how to use this command is shown in Table 17.

     QUEUE 
     This command starts/stops/resets a queue of OS printer console messages. A current message pointer in a script is set, reset, and cleared with the QUEUE command. 
     The ICS has one large message queue that holds all of the incoming printer console messages. In the preferred embodiment, the queue holds the most recent 6500 messages. The oldest message is discarded when a new message is added (i.e., a circular message queue). Each script has multiple current message pointers into the message queue. The message pointers are set and reset with the QUEUE command and advanced with the READMSG command. The next message in a queue is retrieved with the READMSG command. QUEUE only creates a queue for OS printer console messages. If a port is specified, it must be an OS printer console port. If a port is not specified, the script must be executing on an OS icon. Only QUEUE (RESET) a queue that has had the QUEUE(ON) command activated on it. 
     The syntax for the command is: 
     QUEUE(Operation{, Port}) 
     where,

     READMSG 
     This command reads the next message from a script&#39;s message queue. The next message is defined by a script&#39;s current message pointer created with the QUEUE command. The entire message is placed in the array specified by the $MSG array parm. Each word in the message is placed sequentially by position into the array&#39;s elements ($Msg[ 1] contains the 1st word, $Msg[ 2] contains the 2nd word, $Msg[ 3] contains the 3rd word, etc.). When the queue is empty, the READMSG command acts as specified by the Wait and *Timeout parms. 
     In the preferred embodiment, the QUEUE(ON) must be executed before the READMSG command. READMSG only reads OS printer console messages. If a port is specified, it must be an OS printer console port. If a port is not specified, the script must be executing on an OS icon. 
     The syntax for the command is: 
     READMSG($Msg, Wait, *Timeout{, Port} {, Filter}) 
     where, 
     
         ______________________________________                                    
$Msg       Normal string array. The array to populate                     
           with each word from the message. Each                          
           array element will hold one word. The                          
one        words are split up by &#34;white space&#34;                            
           or more space characters.                                      
Wait                 Numeric expression. The number of seconds            
           to wait before timing out. When the queue                      
           is empty, this number specifies how long                       
           the command waits for a message.                               
*Timeout        Label. The label to jump to when the                      
           READMSG command times out.                                     
Port                 Numeric expression. Optional. The OS                 
           printer console to read a message from. A                      
           queue must already have been created for                       
                           the specified port with the QUEUE()            
           command. If not specified, a message is                        
           read from the default queue (the OS printer                    
           console the script is executing on).                           
Filter             String Expression. Optional. The text in               
                           this string acts as filter criteria - the      
           criteria text must be in the console

     SCANB 
     This command is similar to the SCANP command except for its use with the BLOCKSCAN command. 
     The syntax for the command is: 
     SCANB(Port, Text, *Found) 
     where, 
     
         ______________________________________                                    
Port        Numeric expression. The assigned console                      
                               port number to scan.                       
Text                  Regular expression. The text expression to          
            scan for in the console.                                      
*Found              Label literal. The label to jump to when              
            the Text parm is found within the time                        
                       limit specified by the Wait parm in the            
                       BLOCKSCAN command.                                 
______________________________________                                    
 
    
     SCANP 
     This command searches a console for a specified character string. Script execution can branch based on whether or not the scan was successful within a specified time limit. If found within the number of seconds specified by the Wait parm, script execution continues with the next statement. If not found within the number of seconds specified by the Wait parm, script execution jumps to the label specified by the *Timeout parm. 
     It should be noted that the position of the scan text on the console and character attributes (e.g. only highlighted characters) cannot be specified. In addition, SCANP is not for scanning the printer console. Instead, the READMSG command can be used for reading the printer console. 
     The syntax for the command is: 
     SCANP(Port, Text, Wait, *Timeout{, $ $Array}) 
     where,

           port number to scan.                                           
Text                Regular expression. The text expression to            
                             scan for in the console.                     
Wait                Numeric expression. The number of seconds             
           to wait before timing out when the Text                        
           parm is not found. This number specifies                       
                              how long the command waits for the scan to  
                             be successful.                               
*Timeout         Label literal. The label to jump to when                 
           the Wait time expires.                                         
$Array             Normal string array. Optional. The array               
           to populate with subexpression results, if                     
           any, from the Text parm. Each array                            
           element will contain one subexpression                         
           result - element one will hold the result                      
                           for subexpression one, element two will        
           hold the result for subexpression two, etc.                    
           The subexpressions are &#34;numbered&#34; from left                    
           to right in the Text parm. $Array is only                      
           populated when the Text parm contains                          
                           subexpressions and the scan text is

     In the preferred embodiment, only the first 9 subexpression results can be returned; however, it will be appreciated by those skilled in the art that provisions for returning more or less results could be devised without departing from the scope and spirit of the present invention. 
     SCRNTEXT 
     This command returns characters from a console screen. The characters begin at absolute position Start and continue for Length on the console represented by Port are returned. 
     The syntax for the command is:

                            * its column quantity.                        
Length             Numeric expression. The quantity of                    
           characters to copy from the console. The                       
           minimum value is 1 and the maximum value is                    
           the console&#39;s row quantity * its column                        
           quantity less the Start parm.

     Turning now to FIG. 21, a high level description of the UNIX®-based daemons and functions which implement a preferred embodiment ICS 100. These daemons and functions are described in detail in reference to the flowcharts shown in FIGS. 22-74. The shared memory 114 (i.e., the common data storage) preferably consists of RAM which is accessed by many of the daemons whenever data needs to be retrieved for processing by an individual daemon or updated in the shared memory. In addition, long term storage is provided by one or more hard disk drives interfaced through the message log 208 and system log manager 210. The message log 208 is described in more detail in the following description in reference to FIG. 52. Similarly, the description below for FIG. 64 describes the system log manager 210. 
     This shared memory 114 also holds copies of or &#34;virtual&#34; consoles 230 for each of the mainframe or other computer system consoles which are being monitored by the ICS 100. By being placed in this shared memory 114, the data within the virtual consoles can displayed at will on a computer monitor or filtered for monitoring information such as error conditions. In addition, the shared memory 114 includes a queue of messages 232 being sent to the ICS 100 and a set of filtered messages 234 which have been processed or filtered by one or more daemons. 
     FIGS. 54 and 62, provide some details on the operations of the object manager 200. The object manager 200 interacts with other function and daemons in part through user input provided via the task manager graphic user interface 212 and the script manager 202. The script manager is described in some detail in reference to FIGS. 42, 44, and 60. The interactions of the object manager 200 and the script manager 202 are so closely intertwined that in the preferred embodiment a means of direct communication between the two daemons (i.e., UNIX® processes) is provided. However, like all other daemons in the ICS 100 communications between the two daemons may also be done via the shared memory 114 where data is placed in the shared memory 114 by one daemon and then copied out again by another daemon. 
     The filter manager 204 is described in reference to FIGS. 50 and 51. The print 3270 daemons 206 are described in reference to FIGS. 33 and 57. The main or master ICS control daemon 214 is described in reference to FIG. 45. The power manager 218 is described in reference to FIG. 56. The I/O manager 220 is described in reference to FIG. 34. The display manager 222 for a 3270 terminal is described in reference to FIG. 37. The operations of an RS-232 display 226 and I/O 224 are described in reference to FIGS. 22, 23, and 58. The filter window or display 228 is described in reference to FIG. 39. 
     These and other daemons or functions are described below. 
     Referring first to FIG. 22, there is shown a method for displaying the RS-232 screens. First, the fallback resources are modified 300 to contain the proper font list. The main window is created 302. The arguments on the command line are processed 304. The configuration is read 306. The module is attached 308 to the shared memory. The module is connected 310 to the server&#39;s socket. The socket is added 312 to the application context import ports for handling. The display is checked 314 to see if it is an icon. If it is, then the screen is iconified 316. Alternatively, the proper console window is displayed 318. A time out is prepared 320 to look for any changes in the status of the RS-232 screens. Finally, the main event loop is called 322. 
     Referring now to FIG. 23, there is shown a method for operating an RS-232 I/O handler for the ICS system. First, the command line is processed 324. The system configuration is read 326. The module is attached 328 to four shared memories: system shared memory, configuration shared memory, RS-232 shared memory and printer shared memory. The module is attached to the message queue 330. Then the mutexes are initialized 332. Then a new envelope is created 334 through which any programs that the module forks are passed. Each port is set up 336. The thread is set up 338 to watch for people to connect. Receipt of incoming signals is handled 340. If it is time for system exit 342 the module goes to sleep 344. Alternatively, the socket connections are shut down 346. 
     Referring now to FIG. 24, there is shown a method of displaying an application summary window. First, all strings are shown 348 to the message display window. The main initialization is performed 350. If there is an initialization error 352 the application summary window quits 354. Alternatively, a security check is performed 356 to assure the user has access to this module. If the user is not okay 358, an error message is printed 360 and the application summary window is exited 362. Alternatively, the application summary window is initialized 364. If there are any initialization errors 366, the application summary window is exited 368. Alternatively, the module ends 370. 
     Referring now to FIG. 25, there is shown a method of configuring the I/O box. First, the external bus memory and the I/O port are mapped 372. If a mapping error is found 374, then the external bus memory and I/O ports are unmapped 376. Alternatively, the configuration data is shown 378 and the module ends 380. 
     Referring now to FIG. 26, there is shown a method of triggering an alarm manager. First, if there is no display available 382 an alarm is sent 384 via STOUDT. Alternatively, an alarm is sent 386 via X connection. 
     Referring now to FIG. 27, there is shown a method of checking the color scheme. First, the command line is parsed 388. Then, upon user request, either the printer help options or the version number of an alarm manger is displayed 390. The user is told 392 that the color file checker is started. The RGB file is opened 394 and checked, and any errors found are displayed 396. The color number requested is checked for validity 398 and it is checked for being a duplicate 400. If the color number is valid and is not a duplicate, then the color table is updated 402 with the data contained in the RGB file. In the event either the color number is not valid or the color number is a duplicate, then the color table is not updated with the RGB file data. In either case the results are displayed 404. 
     Referring now to FIG. 28 there is shown a method of operating the configuration manager. First, the command line is parsed 406. Upon user request, either the help message or aversion number is displayed 408. &#34;Configuration Manager Started&#34; is displayed 410. The configuration manager is initialized 412. If there was an error during initialization 414, an error message is displayed 416 and the module ends 418. Alternatively, a signal handler is set up 420. The message from the host system is checked 422. The system is configured 424 for the appropriate MVS system, whether it is old or new. The system is configured 426 for the appropriate style error, whether it is matrix or &#34;unit&#34;. Configuration units are added 428 if necessary. The unit configuration table is sorted 430 by address. The configuration buffer is updated and synchronized 432. The configuration buffer is saved 434. &#34;Configuration Manager Ended&#34; is displayed 436. 
     Referring now to FIG. 29, there is shown a module for compiling a script. First, &#34;Script Compiler Started&#34; is displayed 438. The command line is parsed 440. Upon user request, either printer help options or the version number is displayed 442. If the script size exceeds the maximum screen size 444, a message is displayed 446. Script memory is allocated 448. If there is insufficient memory 450 then the process is ended. Alternatively, the hardware configuration file is read 452. See FIG. 51. If there is a hardware configuration error 454, the module is ended. Alternatively, if the script file name is not given 456, then the module is ended. Alternatively, the command line is parsed 458. File names are obtained 460. File names are configured 462. If the script file name is too large 464, then &#34;Illegal Script File Name&#34; is displayed 466 and the next script file is loaded 466. Alternatively, the color definition is obtained 468. Compilation and initialization are begun 470. The script source code is read 472. Phase 1 of the script compiler is run 474. Phase 2 of the script compiler is run 476. Any file skipped due to an error are reported 478. The number of compiled errors found are reported 480. If there are more files to compile 482, the files are run through the above procedure from 458. Alternatively, the script compiler is ended and the user is so notified 484. 
     Referring now to FIG. 30, there is shown a module for checking the configuration file. First, the command line is parsed 486. The help message or version number is displayed 488. The message &#34;Configuration File Checker Started&#34; is displayed 490. The system definition file is read 492 (see FIG. 50). If errors are found 494, then it is indicated 496 that an invalid configuration definition is found. Alternatively it is indicated 498 that all definitions are correct and the module returns 500 to the calling function. 
     Referring now to FIG. 31, there is shown a module for initializing the configuration buffer. First, the command line is received 502. The extent of verbosity is determined 504. A help message or version number is displayed 506 upon user request. The message &#34;Configuration Buffer Initializer Started&#34; is displayed 508. Configurations for cpu, channel, group, unit, operating system and software are initialized 510. Any errors are reported to the user 512. The initializer is closed 514 and any errors are indicated 514. &#34;Configuration Buffer Initializer Ended&#34; is displayed 516. 
     Referring now to FIG. 32, there is shown a module for converting the message database. First, the message &#34;Message Database Converter Started&#34; is displayed 518. A help message or version number is displayed 520 upon user request. An input message description file, an output message index file, and an output message data file are received 522. Any error messages are displayed 524. The message is converted 526. Any message description, message ID or unacceptable format errors are displayed 528. Duplicate message ID definitions are searched 530 and displayed 530 if found. The number of errors found in the conversion is displayed 532. 
     Referring now to FIG. 33, there is shown a module for emulating a 3270 printer. First, a help message or version number is displayed 534 upon user request. The user input is determined 536.

     The present invention can be summarized in reference to FIGS. 1 and 2 which are block diagram of the preferred embodiment ICS 100. 
     In one embodiment of the present invention, an electronic control system 100 external to a computer system 140, 148, and 150 for controlling processes in the computer system is provided. A graphical user interface 136 which presents data as graphical information to a user on a display device 138. An input device 122 which receives data input by the user through a keyboard 124 or mouse 126. A processor 110 is operatively coupled to the graphical user interface 136, the input device 122, and the computer system, to control operations of the computer system based on user input provided through the input device 122 in response to processing rules displayed to the user by the graphical user interface 136. As a result of this configuration of components in the control system 100, automatic external and direct control of the computer system can be accomplished by only utilizing preexisting computer system signals received from the computer system and control signals sent to the computer system (i.e., no additional hardware or software needs to be added to the computer system being monitored). 
     The control system 100 preferably includes a receiving device 134 which receives the preexisting computer system generated signals which are output by a particular process in the computer system and a sending device 134 which sends the control signals to the computer system. In addition, the control system 100 includes a transformation device 118 operatively coupled to the receiving device 134 and the sending device 134 which transforms the received preexisting computer system generated signals into an incoming plurality of message signals in a common message signal format and which transforms an outgoing plurality of message signals into the control signals. A common data storage 114 is operatively coupled to the transformation device 118 and the processor 110 to store the incoming and the outgoing message signals. As a result, the processor 110 performs different operations on a particular message signal of the incoming plurality of message signals retrieved from the common data storage 114 based on the processing rules and stores a particular message signal of the outgoing plurality of message signals in the common data storage 114 based on the processing rules.
