Description:
BACKGROUND OF THE INVENTION  
         [0001]    The present invention is related to a managing computer connected to a network to which a plurality of computers are connected, for managing these computers. More specifically, the present invention is directed to a technique capable of managing administrate operations executed in the respective computers in a batch mode by the managing computer.  
           [0002]    Managing computers for managing administrate operations are described in U.S. Pat. No. 5,169,655 entitled to Weng et al., and U.S. Pat. No. 5,642,508 entitled to Miyazawa. The administrate operations involve a job execution process; and a process executed when a specific event occurs.  
           [0003]    In a large-scaled computer system where a plurality of administrate operations may be combined with each other to be executed, since definitions as to the respective administrate operations must be separately performed and also execution results must be independently confirmed, the management for the total computer system can be hardly carried out.  
           [0004]    More specifically, in a large-scaled computer system, there are certain possibilities that a plurality of administrate operations which are executed in combination with each other are executed over a plurality of computers. Under such a circumstance, in order to realize a total management as a computer system, processed contents as to all of administrate operations may be preferably defined and execution results thereof may be preferably confirmed by using a single computer, namely a single managing computer.  
           [0005]    However, in the case that the definitions of the processed contents and the confirmations of the execution results as to all of the administrate operations may be performed by one managing computer, since the managing computer must be communicated with the respective computers, a specific care should be paid to the network traffics.  
         SUMMARY OF THE INVENTION  
         [0006]    Therefore, an object of the present invention is to realize such a computer system to which a plurality of computers are connected. In this computer system, a managing computer for managing these computers can manage administrate operations executed in the respective computers are managed in a batch mode.  
           [0007]    Furthermore, another object of the present invention is to avoid such that an extra load is given to a network connecting a managing computer group, which is caused by an operation managing computer.  
           [0008]    To achieve the above-described object, there is provided a managing computer comprising:

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0044]    Referring now to drawings, embodiment modes of the present invention will be described.  
         [0045]    [0045]FIG. 1 schematically indicates an entire arrangement of a computer system according to an embodiment of the present invention. In this drawing, reference numeral  401  indicates a managing computer; reference numerals  402  to  407  computers which constitute subjects managed by the managing computer; and reference numerals  408  to  413  show networks.  
         [0046]    In the computer system according to this embodiment, the managing computer  401  can form in a batch mode operation definition information used to define schedules of administrate operations executed in the computers  402  to  407 , and furthermore the managing computer  401  can manage in a batch mode both log information indicative of execution results obtained from the computers  402  to  407 , and event information indicative of events occurred during execution stage.  
         [0047]    As a result, since the managing computer  401  can save the operation definition information, the log information, and the event information in a database form, this managing computer  401  may refer to the above-described information, if necessary, and also may display various items related to the above-explained information.  
         [0048]    [0048]FIG. 2 schematically represents a system arrangement used to form by the managing computer  401 , the operation definition information which defines the schedules of the administrate operations executed by the computers  402  to  407 . It should be understood that although FIG. 2 represents only one computer  402  and the managing computer  401  of FIG. 1, other computers  403  to  407  may be similarly displayed.  
         [0049]    As indicated in FIG. 2, the managing computer  401  is arranged by a managing application unit  101 , a definition information managing unit  102 , and a database  103 .  
         [0050]    The managing application unit  101  contains a definition unit  104  and an integrated management screen display unit  105 . The batched definition unit  104  forms operation definition information used to define a schedule of administrate operations executed by the computers  402  to  407 . The integrated management screen display unit  105  displays an integrated management screen (will be discussed later) and so on. The definition information managing unit  102  contains a definition information distributing/acquiring unit  106  for distributing the operation definition information to the computers  402  to  407 , and for acquiring the operation definition information from the computers  402  to  407 . This definition information managing unit  102  stores the operation definition information into the database  103 , and retrieves/referring to the operation definition information stored in the database  103 .  
         [0051]    As indicated in FIG. 2, each of the computers  402  to  407  is arranged by employing an operation execution unit and an integrated management agent  113 . This operation execution unit contains a job execution control unit  110 , a power supply control unit  111 , a print execution control unit  112  and the like, which execute the administrate operation defined by the operation definition information.  
         [0052]    The integrated management agent  113  contains a definition information expanding unit  114  and a definition information notifying unit  115 . The definition information expanding unit  114  expands operation definition information of a portion related to the own computer from the operation definition information distributed from the managing computer  401 . The definition information notifying unit  115  notifies to the managing computer  401 , the operation definition information related to the own computer and involving also the operation definition information individually formed by the own computer.  
         [0053]    [0053]FIG. 3 represents a system arrangement in which both log information and event information of administrate operations executed by the computers  402  to  407  are managed in a batch mode by the managing computer  401 . Although FIG. 3 shows only the managing computer  401  and one computer  402  of FIG. 1, other computers  403  to  407  are similarly applied to this computer  402 .  
         [0054]    As indicated in FIG. 3, the managing computer  401  is arranged by employing a managing application unit  101 , an event/log managing unit  201 , and a database  103 .  
         [0055]    The managing application unit  101  contains the integrated management screen display unit  105  for displaying the integrated management screen (will be explained later) and so on. The event/log managing unit  201  contains the event/log acquiring unit  202  for acquiring the event information and the log information from the computers  402  to  407 , and retrieves/refers to the event information and the log information, which are stored in the database  103 . Also, the event/log managing unit  201  stores into the database  103  and outputs to the integrated management screen display unit  105  as to event information which should be notified in real time to an operation manager and so on.  
         [0056]    As indicated in FIG. 3, each of the computers  402  to  407  is arranged by employing an operation execution unit and an integrated management agent  113 . This operation execution unit contains a job execution control unit  110 , a power supply control unit  111 , a print execution control unit  112  and the like, which execute the administrate operation defined by the operation definition information.  
         [0057]    The integrated management agent  113  contains a normalizing unit  210  and an event/log notifying unit  211 . The normalizing unit  210  converts both log information and event information of administrate operation executed by the own computer into a predetermined common format. The event/log notifying unit  211  notifies the normalized log information and the normalized event information to the managing computer  401 .  
         [0058]    [0058]FIG. 4 schematically indicates a hardware structure of the managing computer  401  and the computers  402  to  407 .  
         [0059]    As indicated in FIG. 4, each of the computers is arranged by employing a central processing unit  301 , a main storage apparatus  302 , a network control apparatus  305 , a disk control apparatus  307 , and a display control apparatus  309 . The network control apparatus  305  controls input/output of data between this network control apparatus  305  and a network such as a communication line  303  and a local area network  304 . The disk control apparatus  307  controls a disk apparatus  306  and also input/output thereof. The display control apparatus  309  controls a display apparatus  308  and also input/output thereof.  
         [0060]    Among the structural blocks of FIG. 2 and FIG. 3, the database  103  is realized on the disk apparatus  306 . Other structural blocks are realized in such a way that a program stored in the disk apparatus  306  is loaded by the central processing unit  301  on the main storage apparatus  302 . It should be noted that this program may be recorded on, for instance, a recording medium such as a CD-ROM, and then may be read into a driver (not shown) to be stored into the disk apparatus  306 .  
         [0061]    Referring now to FIG. 5, a description will be made of a sequential operation for defining and distributing the operation definition information in the system arrangement of FIG. 2.  
         [0062]    As indicated in FIG. 5, in the managing computer  401 , the definition information managing unit  102  stores into the database  103 , the operation definition information defined by the batched definition unit  104  contained in the managing application unit  101  (step  601 ). The operation definition information stored in the database  103  is distributed to the computers  402  to  407  at preselected timing by the definition information distributing/acquiring unit  106  contained in the definition information managing unit  102  (step  602 ).  
         [0063]    In the computers  402  to  407  to which the operation definition information is distributed, the definition information expanding unit  114  owned by the integrated management agent  113  expands operation definition information of a portion related to the own computer from the distributed operation definition information. The definition information expanding unit  114  transfers the expanded operation information to the operation execution unit such as the job execution control unit  110 , the power supply control unit  111 , and the print execution control unit  112  (step  603 ). The operation execution unit executes the administrate operation defined by the respective transferred operation definition information (step  604 ).  
         [0064]    On the other hand, in the managing computer  401 , the definition information distributing/acquiring unit  106  of the definition information managing unit  102  acquires from the computers  402  to  407 , the operation definition information related to the computers  402  to  407  and also containing the operation definition information individually formed in the computers  402  to  407  (step  605 ). Subsequently, the definition information managing unit  102  stores the acquired operation definition information into the database  103  (step  606 ).  
         [0065]    In the case that the integrated screen display unit  105  owned by the managing application unit  101  displays an integrated management screen (will be explained later) in response to a reference request issued from an operation manager and the like, the operation definition information stored into the database  103  in this manner will be retrieved/referred by the definition information managing unit  102 .  
         [0066]    It should be understood that the operation definition information may be acquired in such a way that the definition information distributing/acquiring unit  106  contained in the definition information managing unit  102  in the managing computer  401  periodically issues a command to the computers  402  to  407 . Alternatively, the acquisition of the operation definition information may be realized by such that the definition information notifying unit  115  owned by the integrated management agent  113  in the computers  402  to  407  initiatively notifies the operation definition information to the managing computer  401  at preselected timing.  
         [0067]    [0067]FIG. 6 shows an example of operation definition information which is defined by the managing computer  401 . In this drawing, reference numeral  701  shows operation definition information.  
         [0068]    In a definition of the operation definition information  701 , a “definition subject  710 ” corresponds to a portion for defining a computer to be defined. The definition subject  710  may designate a group constituted by a plurality of computers, and a single computer. As represented in FIG. 6, it should be understood that when predetermined information (in this case, “default”) is designated in “definition subject  710 ”, this information implies that all of the computers are the definition subjects.  
         [0069]    A “power supply control ( 711 )” corresponds to a portion used to define an execution schedule of a power supply turning ON/OFF process of a computer to be defined, and a turning OFF method. A “job execution control ( 712 )” corresponds to a portion used to define a job net on a computer to be defined, and a job on the job net. In the example of FIG. 6, a “job net A” defines that after an execution of a “job A 1 ” has been completed, a “job A 21 ” and a “job A 22 ” are executed in a parallel manner, and then when the executions of both these jobs A 21  and A 22  are completed, a “job A 3 ” is executed.  
         [0070]    As previously explained, since the operation manager and the like designate such a computer for executing the schedule of the respective administrate operations and also the respective administrate operations in the managing computer  401 , the operation definition information can be formed in a batch manner, on which the schedule of the administrate operation to be executed by the computer is defined.  
         [0071]    [0071]FIG. 7A and FIG. 7B show an example of the operation definition information  701  of FIG. 6 which is expanded by the computer. In FIG. 7A and FIG. 7B, there are shown operation definition information  801  to  802  which have been expanded in the computers  402  to  407  of FIG. 2. Each of the above-described operation definition information  801  and  802  is transferred to the power supply control unit  111  and the job execution control unit  110 .  
         [0072]    Next, a sequential operation for acquiring and for managing in a batch mode the event information and the log information in the system arrangement of FIG. 3 will now be described with reference to FIG. 5.  
         [0073]    As indicated in FIG. 5, in such a case that either the event information or the log information notified from the administrate operation unit is equal to a preselected sort of information which should be notified to the managing computer  401 , the normalizing unit  210  owned by the integrated management agent  113  in each of the computers  402  to  407  converts this event, or log information into a common format to which a discrimination of event/log information is added. Then, the converted common format is notified by the event/log notifying unit  211  to the managing computer  401  (step  610 ).  
         [0074]    In the managing computer  401  to which either the event information or the log information is notified, the event/log acquiring unit  202  owned by the event/log managing unit  201  stores the notified event information, or the notified log information into the database  103  (step  611 ). The log information is related to an abnormal state occurred during processing operation and includes information related to an abnormal state occurred during processing operation, whereas the event information is such information which is more important and concise than the former and necessary to inform to the manager computer in real time as to an urgent abnormal event occurred in the operation stage to be cared for by an operator. As a result, in the case that the event information is notified, it is preferable to immediately display this event information on the display apparatus  308  by the integrated management screen display unit  105  owned by the managing application unit  101  (step  612 ). It should also be noted that information may be discriminated as either log information or event information based upon discrimination contained in this information. As another embodiment, this information may be discriminated as either log information or even information based upon the path through which this information is transferred.  
         [0075]    As explained above, in the case that the integrated management screen display unit  105  owned by the managing application unit  101  displays an integrated management screen (will be explained later) in response to a reference request sent from the operation manager, both the event information and the log information stored in the database  103  are retrieved/referred by the definition information managing unit  102 .  
         [0076]    The notifications of the event information and the log information may be preferably realized as to such event information with a high real time characteristic (in particular, event information indicative of failure) as follows. In the computers  402  to  407 , the event/log notifying unit  211  owned by the integrated management agent  113  initiatively notifies the event information to the managing computer  401 . As to the notification of the log information, in the managing computer  401 , the event/log acquiring unit  202  owned by the event/log managing unit  201  may be realized by regularly issuing a command to the computers  402  to  407 . Alternatively, the notification of the log information may be realized by that in the computers  402  to  407 , the event/log notifying unit  211  owned by the integrated management agent  113  initiatively notifies the log information to the managing computer  401  at preselected timing.  
         [0077]    Subsequently, referring now to FIG. 8, a description will be made of one example of an integrated management screen which is displayed by the integrated management screen display unit  103  owned by the managing application unit  101  in the managing computer  401 .  
         [0078]    As previously explained, since the operation definition information, the event information, and the log information are stored in the database  103  in the managing computer  401 , the operation manager and the like may grasp the operations conditions of the computer system by utilizing the above-explained information. In other words, within the managing computer  401 , the integrated management screen display unit  105  owned by the managing application unit  101  causes the definition information managing unit  102  to retrieve/refer to such information which is required by the operation manager to refer to. Then, this integrated management screen display unit  105  forms as integrated management screen by using the retrieved/referred information, and displays the formed integrated management screen on the display apparatus  308 . As a result, the operation manager can grasp the operation condition of the computer system by observing the integrated management screen displayed on the display apparatus  308 .  
         [0079]    In FIG. 8, a first screen  501  is an integrated management screen used to confirm computers managed by the managing computer  401  and also to confirm a group of these computers. In this example, four sets of computers A to D are indicated. The respective computers A to D are displayed as icons. For example, in the first screen  501 , the operation manager double-clicks “computer A ( 502 )” by using a mouse, so that the first screen  501  can be transferred to a second screen  503 .  
         [0080]    Also, in FIG. 8, the second screen  503  is an integrated management screen used to confirm an operation condition of “computer A ( 502 )”. With respect to the “computer A ( 502 )”, a present job execution condition ( 504 ), a list ( 505 ) of a job net whose execution is defined on the “computer A”, and a list ( 506 ) of log information corresponding to a past operation history are displayed in a message form on this second screen  503 . For example, when the operation manager wants to confirm an operation condition related to “job net A” on the second screen  503 , the operation manager double-clicks a column related to “job net A” listed in the job net list  505  by using the mouse, so that the second screen  503  can be transferred to a third screen  507 .  
         [0081]    Also, in FIG. 8, the third screen  507  is an integrated management screen related to “job net A” on “computer A”. This integrated management screen indicates such operation definition information on which a series of administrate operations are defined as to “computer A”, i.e., “turning ON of power supply ( 509 )”, “execution of job net A ( 510 )”, and “printing of execution result ( 511 )”.  
         [0082]    It should be noted that these administrate operations  509  to  511  are displayed as icons. Since a display mode of each of these icons is changed (for instance, color and shape are changed), various sorts of conditions may be displayed such as “not yet executed”, “under execution”, “execution is ended under normal state”, and “execution is ended under abnormal state”. In this case, when the display modes of the respective icons are changed by the integrated management screen display unit  105 , the latest event information of the corresponding administrate operations ( 509  to  511 ) is preferably acquired by the event/log acquiring unit  202  owned by the event/log managing unit  201 .  
         [0083]    For example, when “job net A ( 501 )” is double-clicked by using the mouse by the operation manager, the third screen  507  can be transferred to a sixth screen  514 .  
         [0084]    Also, in FIG. 8, a fifth screen  512  corresponds to an integrated management screen used to confirm the operation definition information displayed on the third screen ( 507 ) in a calendar format. For example, since the operation manager selects menu of “calendar display” (not shown) on the third screen  507 , the third screen  507  can be transferred to the fifth screen  512 . In this example, this fifth screen  512  displays that the job seen on the third screen is executed on a date  513  of a hatched portion.  
         [0085]    Also, in FIG. 8, a sixth screen  514  is a detailed integrated management screen related to “job net A” on “computer A”. This sixth screen  514  defines such that as to “job net A”, after an execution of “job A 1  ( 515 )” is completed, both “job A 21  ( 516 )” and “job A 22  ( 517 )” are executed in a parallel manner, and when the executions of both “job A 21  ( 516 )” and “job A 22  ( 517 )” are completed, “job A 3  ( 518 )” is executed.  
         [0086]    It should also be noted that these jobs are displayed as icons. Since a display mode of each of these icons is changed (for instance, color is changed), various sorts of conditions may be displayed such as “not yet executed”, “under execution”, “execution is ended under normal state”, and “execution is ended under abnormal state”. In this case, when the display modes of the respective icons are changed by the integrated management screen display unit  105 , the latest event information of the corresponding administrate operations ( 509  to  511 ) is preferably acquired by the event/log acquiring unit  202  owned by the event/log managing unit  201 .  
         [0087]    Also, in FIG. 8, a fourth screen  508  corresponds to an integrated management screen used to confirm a log with respect to each of job nets. For instance, since the operation manager double-clicks a list ( 506 ) of the log information on the second screen  503 , the second screen  503  can be transferred to the fourth screen  508 . Alternatively, for example, while the operation manager designates a column related to “job net A” within the job list  505  by clicking this column by using the mouse, this operation manager selects menu of “log display” (not shown). As a result, the second screen  503  may be transferred to another screen (not shown) on which only log information of “job net A” is displayed.  
         [0088]    It should be understood that when the operation manager selects, for example, the corresponding menu within any of the second screen  504  to the sixth screen  514 , the present screen may be transferred to other screens involving such not-shown screens (event information display screen, statistical display screen, operation definition information updating screen etc.). It will be possible to click a certain message shown in screen  508  to additionally display the window  514  or  507  as indicated with arrows.  
         [0089]    As previously explained, in accordance with this embodiment, in the managing computer  401 , the operation definition information related to the respective computers is displayed in connection with both the log information and the event information of the administrate operations defined by this operation definition information. As a consequence the operation manager can grasp the operation conditions of the computer system, and furthermore can readily reflect the grasped operation conditions onto a further plan of the operation schedule.  
         [0090]    As previously described, after the event information is notified, the managing computer  401  preferably and immediately displays this notified event information on the display apparatus  308 . At this time, a screen displayed in the managing computer  401  is represented in, for instance, FIG. 9A.  
         [0091]    [0091]FIG. 9A represents an example of a screen on which event information of a computer A is displayed as a message among the notified event information. In this drawing, the message is constructed of an importance degree  901  of the event information, day/time  902  to  903  when the event is notified, a computer  904  of a notification source, and a message main body  905 .  
         [0092]    The managing computer  401  may display all of the notified event information as a message. Alternatively, as indicated in FIG. 9B, the managing computer  401  may display only pre-designated sorts of event information. As a pre-designated basis, the following items may be conceived, e.g., an importance degree; a range for a date and a time instant; a computer of a notification source; a sort of administrate operation; and a pattern of a character string contained in event information. The operation manager may designate a sort of event information displayed as a message by either the managing computer  401  or the respective computers  402  to  407 .  
         [0093]    Then, in the managing computer  401 , the event/log managing unit  201  judges as to whether or not the notified event information is displayed as the message. The event/log managing unit  201  immediately notifies to the integrated management screen display unit  105  owned by the managing application unit  101 , such event information which is judged to be displayed as a message. Then, the integrated management screen display unit  105  displays this judged event information. Therefore, for instance, as represented in FIG. 9, only such event information indicative of a failure may be displayed as a message. It should be understood that event/log managing unit  201  stores the notified event information into the database  103  irrespective of such a judgment result as to whether or not the notified event information is displayed as the message.  
         [0094]    [0094]FIG. 10A and FIG. 10B represent one example of structures of various sorts of tables on the database  103 . In the drawings, reference numeral  1001  shows an event/log table, and reference numeral  1002  indicates an operation definition table.  
         [0095]    The event/log table  1001  is such a table used to store thereinto the events and the log information acquired from the computer by the managing computer  401  in a time sequence. A single record is arranged by “identifier ( 1010 )” “computer name ( 1011 )”, “time ( 1012 )”, “event/log sort ( 1013 )”, “identifier ( 1014 )”, and “detailed information ( 1015 )”. The identifier  1010  is for the event information and the log information. The computer name  1011  is a name of a computer for notifying this information. The time  1012  is time when this information is notified. The sort  1013  is the sort of this information. The identifier  1014  is an identifier of operation definition information on which administrate operation where this information is produced is defined. In the computer, the information  1010  to  1014  other than the detailed information  1015  is normalized as the common format commonly used to all of the event information and the log information by the normalizing unit  210  owned by the integrated management agent  113 .  
         [0096]    As indicated in FIG. 10B to FIG. 10D, an operation definition table  1002  is constituted by a common table  1003  arranged by an identifier  1016  of operation definition information, a name ( 1017 ) of a computer to be defined, and a sort ( 1018 ) of operation definition information; and also operation definition detailed tables  1004  to  1005  corresponding to the respective sorts ( 1018 ) of the operation definition information.  
         [0097]    The operation definition detailed table  1004  related to the power supply control is arranged by, for example, an identifier ( 1019 ) of operation definition information; a power supply initiation date ( 1020 ); a power supply initiation time ( 1021 ); and a power supply turn-OFF date ( 1022 ), and also a power supply turn-OFF time ( 1023 ). The operation definition detailed table  1005  related to the job net is arranged by, for instance, an identifier ( 1024 ) of operation definition information; a name ( 1025 ) of a job net; a job net initiation date ( 1026 ); a job net initiation time ( 1027 ); and a structural job ( 1028 ).  
         [0098]    In the managing computer  401 , both the definition information managing unit  102  and the event/log managing unit  201  retrieve the tables  1001  to  1004  shown in FIG. 10A to FIG. 10D based on a language of, for instance, SQL. As a result, the integrated management screen display unit  105  owned by the managing application unit  101  can display such a screen as indicated in FIG. 8. In particular, the relationship among the event information, the log information, and the operation definition information may be established by employing the identifier ( 1014 ) of the operation definition information contained in the event/log table  1001  and the identifiers  1016 ,  1019 ,  1024  of the operation definition information contained in the operation definition table  1002 .  
         [0099]    It should be noted that when the screen is displayed, in such a case that information required to be displayed is not present in the tables  1001  to  1004  of FIG. 10, the managing computer  401  is operated in a similar manner to that shown in FIG. 5 so as to acquire this information required to be displayed.  
         [0100]    In the case that such information indicative of a failure occurred in operation conditions of the computer system is notified as an event, this computer system may be operated as follows. First, for example, when a specific job is accomplished under abnormal state while a job net is being executed, after removing a factor for causing this abnormally ended job (e.g., a specific file required to execute a job is not present), the computer system may instruct that this interrupted job is restarted. This instruction may be realized as follows. That is, as indicated in FIG. 11 , in the managing computer, “reexecution command” for designating “subject computer”, “job net name”, “job name to be reexecuted” is entered ( 1101 ); this command is transferred to the above-explained subject computer ( 1102 ) so as to be executed ( 1103 ). Secondly, the computer system may instruct this job net to be canceled. This second idea may be realized as follows. That is, as shown in FIG. 11, in the managing computer, “cancel command” for designating “subject computer ” and “job net name” is entered ( 1101 ); this command is transferred to the above-described subject computer ( 1102 ) so as to be executed ( 1103 ). Furthermore, thirdly, when a specific job is ended under abnormal state while a job net is being executed, a specific job and also a specific job net, by which an abnormal end event is previously defined as a trigger, may be executed. This alternative method may be realized as follows. That is, as represented in FIG. 12, while the managing computer defines such a process operation which should be executed when a specific event is received ( 1201 ), when the managing computer receives this specific event as shown in FIG. 13 ( 1301 ), this managing computer instructs a subject computer to execute the designated process operation ( 1302 ). Then, the subject computer may execute this instruction ( 1303 ). At this time, the definition of either the job or the job net which should be executed by the subject computer may be transferred to be registered when the instruction is issued. Otherwise, this definition may be previously transferred to be registered.  
         [0101]    Subsequently, a description will now be made of effects achieved in such a case that the operation definition information, the event information, and the log information are processed in the database form by the managing computer  401  to be stored.  
         [0102]    As a first effect, a network traffic can be reduced. In accordance with the present invention, since the operation definition information, the event information, and the log information are stored in the database form by the managing computer  401 , the managing computer  401  need not acquire the necessary information from the computer every time the operation manager and the like refer to these information.  
         [0103]    For instance, in the network structure of FIG. 1, when log information of 1 K bytes is acquired from each of the six computers  402  to  407  by the managing computer at a frequency of 1,000 messages/day, a network traffic of 6 M bytes/day is produced. In the case that the log information is referred by the operation manager at a frequency of 10 times/day, a network traffic of 60 M bytes/day in total is produced.  
         [0104]    Furthermore, as to such log information with a low demand of a real-time characteristic, if such log information is collected within such a time range where the normal network traffic is low, for example, in a night time range, the network traffic reduction effect can be apparently achieved.  
         [0105]    As a second effect, since the operation definition information, the event information, and the log information are stored in the database form by the managing computer  401 , as represented in the integrated management screen of FIG. 8, there is another effect that the above-explained information can be readily displayed in various relationship aspects.  
         [0106]    In the computer system according to this embodiment, the computers  402  to  407  are set to be defined in a batch mode by the managing computer  401 . However, it is conceivable that other computers which do not constitute a definition subject are connected to the networks  408  to  413 . In this case, as a method for recognizing a subject computer to be managed by the managing computer  401 , for example, there is a method for automatically detecting the integrated management agent  113  assembled into the computer by using, for example, a broadcasting method. As another method, a subject computer to be defined may be previously defined on the managing computer  401 .  
         [0107]    Also, in accordance with the computer system according to this embodiment, the operation definition information in which the schedule of the administrate operations executed by the computers  402  to  407  is defined can be formed in a batch mode by the managing computer  401 , and furthermore both the log information and the event information of the administrate operations executed by the computers  402  to  407  can be managed by the managing computer  401 , resulting in better results. Alternatively, if at least both the log information and the event information can be managed, then the operation manager may grasp the operation condition of the computer system.
