An upgrade tracking system for tracking aspects of an application upgrade. In various embodiments, the update tracking system includes a statistics collection component configured to collect statistics related an execution of the application upgrade, where the application upgrade includes a plurality of data upgrade files, and where the plurality of data upgrade files are organized into a plurality of functional upgrade groups. The system further includes a timing component configured to report execution timings related to the execution of the application upgrade, and a status component configured to track statuses related to the execution of the application upgrade.
The present application is a continuation of U.S. application Ser. No. 11/923,181, filed Oct. 24, 2007, and entitled “Techniques for Upgrade Dependency Management,” (Atty. Docket No.: 021756-042000US), the entire contents of which is herein incorporated by reference for all purposes.
The present application also incorporates by reference for all purposes the entire contents of the following commonly-assigned, non-provisional US applications:
(1) U.S. Non-Provisional Application entitled “Database Size Tracking and Reporting for Application Upgrades”, (Atty. Docket No. 021756-042020US), filed concurrently herewith.
Embodiments of the present invention relate to software applications, and more particularly relate to techniques for managing aspects of application upgrades.
Upgrades (i.e., patches) for data-driven software applications typically include a number of data upgrade files. These data upgrade files are run against a back-end database of the application, and are generally used to migrate existing application data, seed new application data, and/or modify the application data model to support new and/or enhanced features. In many cases, the execution of one data upgrade file in a patch run will depend on prior executions of one or more other data upgrade files in the patch run. Thus, it is important to track these dependencies and sequence the execution of the data upgrade files accordingly.
In practice, most software developers and development teams do not follow an organized methodology for tracking and managing upgrade dependencies. Rather, they typically determine how to order the execution of data upgrade files within a particular patch run on ad-hoc, file-by-file basis. For example, assume development team A creates an upgrade script “A.sql” and places A.sql in execution phase “X” of an upgrade. Further, assume development team B subsequently creates an upgrade script “B.sql,” which depends on A.sql. Observing that A.sql is set to run in phase X, development team B may decide to place B.sql in a random downstream phase “X+Y” to ensure that B.sql executes after A.sql.
Typically, team B will not be aware of other data upgrade files created by other teams that are also dependent on A.sql. Similarly, team A may not be aware of downstream dependencies on A.sql. (e.g., B.sql). This creates several problems. First, different developers/development teams cannot effectively consolidate the execution of data upgrade files across functional/team boundaries, often resulting in unnecessary execution phases within an upgrade. For example, assume development team C creates an upgrade script “C.sql,” which is dependent on A.sql (but independent of B.sql). Like team B, team C may decide to place C.sql in an execution phase that is downstream from phase X to ensure that C.sql executes after A.sql. However, since team C is unaware of B.sql, team C may decide to place C.sql in a random downstream phase “X+Z” that is different from phase X+Y. As a result, B.sql and C.sql are forced to execute serially, even though they are independent and can be executed simultaneously (i.e., in the same phase). This type of situation undesirably increases the total running time of the upgrade and the downtime of the system to be patched.
Second, development teams cannot easily modify the execution order of data upgrade files within an upgrade without breaking downstream dependencies. For example, if team A moves A.sql to a later execution phase “X+A” (perhaps because of an upstream dependency change) the dependency between A.sql and B.sql and/or the dependency between A.sql and C.sql may be broken. Even if B.sql and C.sql are moved in response to A.sql, those changes might break additional downstream dependencies. The key problem is that no one has a holistic view of all of the inter-file dependencies that may be included in an upgrade. As a result, it is extremely difficult, particularly for large and complex upgrades, to anticipate all of the downstream effects of modifying the sequencing of data upgrade files.
Accordingly, it is desirable to have improved techniques for managing the dependencies of an application upgrade.
Embodiments of the present invention address the foregoing and other such problems by providing techniques for managing dependencies between data upgrade files included in an application upgrade. According to one set of embodiments, the data upgrade files are grouped into functional upgrade groups. A dependency hierarchy for the functional upgrade groups is then created based on dependencies between the data upgrade files. The dependency hierarchy provides a high-level, functional view of the overall dependency flow of an upgrade. In various embodiments, this allows for greater insight into existing and potential dependency issues, leading to more robust and efficient upgrades. In further embodiments, an upgrade tracking system is provided. The upgrade tracking system is configured to track and report detailed analytics related to one or more upgrade runs. In various embodiments, the upgrade tracking system may leverage the grouping of data upgrade files into functional upgrade groups to provide intelligent reporting at a functional level.
According to one embodiment of the present invention, a method for managing dependencies between data upgrade files included in an application upgrade comprises grouping the data upgrade files into functional upgrade groups. A dependency hierarchy is then defined for the functional upgrade groups based on the dependencies between the data upgrade files. In various embodiments, the method may further comprise executing the application upgrade by executing the data upgrade files, and thereafter validating whether the data upgrade files were executed in an order consistent with the dependency hierarchy.
In one set of embodiments, the step of defining the dependency hierarchy includes associating each functional upgrade group with an execution phase. An execution phase represents an execution order for data upgrade files included in the functional upgrade group. In addition, the step of validating whether the data upgrade files were executed in an order consistent with the dependency hierarchy includes validating whether each data upgrade file was executed in the execution phase identified for the data upgrade file's functional upgrade group.
In further embodiments, each functional upgrade group is associated with an upgrade token that uniquely identifies the functional upgrade group, and each data upgrade file includes a reference to the upgrade token of the file's functional upgrade group. In some embodiments, this reference is included in an upgrade definition section defined in each data upgrade file. To validate whether each data upgrade file was executed in the execution phase identified for the data upgrade file's functional upgrade group, the upgrade definition section of the file is parsed to identify the upgrade token included in the section. The functional upgrade group associated with the identified upgrade token is then identified. Finally, the execution phase of this identified functional upgrade group is compared with the actual execution phase in which the data upgrade was run.
According to another embodiment of the present invention, an upgrade tracking system is provided. The update tracking system includes a statistics collection component configured to collect statistics related an execution of an application upgrade, where the application upgrade includes a plurality of data upgrade files, and where the plurality of data upgrade files are organized into a plurality of functional upgrade groups. The system further includes a timing component configured to report execution timings related to the execution of the application upgrade, and a status component configured to track statuses related to the execution of the application upgrade.
In one set of embodiments, the execution timings include execution timings of individual data upgrade files in the plurality of data upgrade files. In additional embodiments, the execution timings may include aggregate execution timings of data upgrade files per functional update group, product family, or some other category. In an exemplary embodiment, the timing component is configured to generate intelligent reports based on execution timings, such as a report that identifies a critical path for the upgrade.
In another set of embodiments, the status component is configured to automatically determine a responsible party for each data upgrade file or each functional upgrade group. One or more status updates may then be received from the responsible party. The one or more status updates may include, for example, an update of a success status indicating whether the data upgrade file or functional upgrade group was executed successfully during the execution of the application upgrade. The one or more status updates may also include an update of a completion status indicating whether the responsible party has completed validation of the data upgrade file or functional upgrade group. The one or more status updates may further include an update of a performance status indicating whether the responsible party has completed a performance review of the data upgrade file or functional upgrade group.
In some embodiments, the status component is configured to automatically log a bug against the responsible party after the execution of the application upgrade. In this manner, the responsible party may be reminded to provide the one or more status updates described above.
In another set of embodiments, the upgrade tracking system further includes a bug integration component configured to report bugs logged against one or more data upgrade files in the plurality of data upgrade files as a result of the execution of the application upgrade. In various embodiments, this reporting is performed by accessing a bug database communicatively coupled with the bug integration component, identifying one or more bugs in the bug database that include a predefined template, and collecting bug information from each identified bug by parsing the predefined template.
In another set of embodiments, the upgrade tracking system further includes a file history component configured to report history information for each data upgrade file in the plurality of data upgrade files. The history information may include, for example, information related to prior executions of the data upgrade file, and execution timings for the prior executions.
According to another embodiment of the present invention, a method for determining database object growth comprises recording baseline sizes for a plurality of database objects, where the baseline sizes are recorded prior to the execution of an application upgrade, and recording upgraded sizes for the plurality of database objects, where the upgraded sizes are recorded subsequent to the execution of the application upgrade. Growth values for the plurality of database objects are then determined based on the baseline sizes and the upgraded sizes.
In additional embodiments, the method may further comprise organizing the plurality of database objects into one or more functional groups or product families, and reporting aggregate database object growth per functional group or product family. In various embodiments, the aggregate database object growth per functional group or product family may be represented by an absolute value, a percentage value, a percentage of total database growth, or the like.

FIG. 1 illustrates a flowchart 100 of the steps performed in managing dependencies between data upgrade files in accordance with an embodiment of the present invention. Using this technique, upgrade dependencies may be managed at a functional level, allowing for greater insight into, and control over, the building and testing of application upgrades. In various embodiments, the processing of flowchart 100 may be implemented in software, hardware, or combinations thereof. For example, as software, flowchart 100 may be implemented as part of an automated upgrade management application. Further, portions of flowchart 100 may be performed manually (i.e., through human intervention). One of ordinary skill in the art would recognize many variations, modifications, and alternatives.
At step 102, data upgrade files that are included as part of an application upgrade are grouped into functional upgrade groups. The functional upgrade groups correspond to functional areas or modules encompassed by the upgrade. In some embodiments, the functional upgrade groups may be fairly granular (e.g., corresponding to small points of functionality). In other embodiments, the functional upgrade groups may be fairly broad (e.g., corresponding to entire product families). In one embodiment, the functional upgrade groups are broad enough to avoid a one-to-one correspondence between data upgrade files and groups, but granular enough to avoid a very small number of groups.
FIG. 2 illustrates a plurality of exemplary data upgrade files (A.sql, B.sql, C.sql, D.sql, E.sql, F.sql, G.sql, H.sql, I.sql, J.sql) grouped into functional upgrade groups 202, 204, 206, 208 (GROUP_1, GROUP_2, GROUP_3, GROUP_4). In one set of embodiments, the data upgrade files correspond to database script files, such as SQL scripts. In other embodiments, the data upgrade files may be written in any scripting or programming language capable of upgrading data in a database or other type of data store.
As shown, each functional upgrade group 202, 204, 206, 208 is associated with a name (GROUP_1, GROUP_2, GROUP_3, and GROUP_4 respectively). In various embodiments, this name (referred to herein as an “upgrade token”) is used to uniquely identify the functional upgrade group. Although not depicted in FIG. 2, data upgrade files A.sql, B.sql, C.sql, D.sql, E.sql, F.sql, G.sql, H.sql, I.sql, and J.sql may have certain inter-file dependencies between them. For the purposes of illustration, assume H.sql is dependent on (i.e., must be executed after) E.sql, E.sql is dependent on B.sql, and G.sql is dependent on A.sql. In this exemplary embodiment, all of the data upgrade files in a given functional upgrade group are independent.
Returning to FIG. 1, after the data upgrade files are grouped, a dependency hierarchy for the functional upgrade groups is defined (104). In one aspect, this involves defining dependencies between the functional upgrade groups that preserve the dependencies between the data upgrade files. FIG. 3 illustrates an exemplary dependency hierarchy 300 for the data upgrade files and functional upgrade groups of FIG. 2. As shown, group 208 is dependent on group 204, and groups 204, 206 are dependent on group 202. This hierarchy preserves the dependencies between E.sql/H.sql, E.sql/B.sql, and G.sql/A sql described above.
Another aspect of defining dependency hierarchy 300 involves identifying execution phases for the functional upgrade groups. As used herein, an execution phase refers to an ordered phase or segment of an upgrade execution/run. Generally speaking, all of the data upgrade files within a particular execution phase may run simultaneously. However, files in a particular execution phase cannot run before files in prior execution phases. By creating mappings between functional upgrade groups and execution phases, a execution order or sequence for the groups (and thus, the data upgrade files within the groups) may be defined.
In one set of embodiments, functional upgrade groups are associated with execution phases according to a rule that allows a group G to be associated with any phase, as long as that phase occurs after the phases of other functional upgrade groups that group G is dependent upon in the dependency hierarchy. This mapping will result in an execution sequence that is consistent with the dependency hierarchy, but may not represent the most efficient ordering of data upgrade files.
In a preferred embodiment, functional upgrade groups are associated with execution phases in a manner that satisfies the rule above, but also seeks to minimize the total number of execution phases. For example, in FIG. 3, group 202 is associated with phase 1 (302), groups 204, 206 are associated with phase 2 (304), and group 208 is associated with phase 3 (306). This mapping represents the most efficient ordering of groups/files for this upgrade. In theory, group 206 could be associated with a phase 4 that occurs after phase 3 (306) because group 206 is only dependent on group 202 (which is in phase 1 (302)). However, by associating group 206 with phase 2 (304), the total number of phases is kept to three (the minimum possible number), thereby minimizing the total running time of the patch run.
Once a dependency hierarchy, such as hierarchy 300 of FIG. 3, has been defined, upgrade dependencies may be managed and organized at the functional level. As a result, changes or additions to the execution sequence of an application upgrade can be better understood and controlled, resulting in more robust and efficient upgrades.
In some embodiments, steps 102, 104 of FIG. 1 may be performed on all of the data upgrade files of an upgrade/patch at a single time. This would most likely occur immediately prior to the building and testing of the patch. In this scenario, dependency management is deferred to the end of the development lifecycle. In other embodiments, steps 102, 104 may be performed incrementally on a file-by-file basis. For example, a data upgrade file may be classified into a functional upgrade group at the time of its creation (102). As additional data upgrade files are created and/or modified, the functional upgrade groups and dependency hierarchy would be modified accordingly.
In one set of embodiments, the definition of functional upgrade groups and a dependency hierarchy (as shown in steps 102, 104 of FIG. 1) may enable automated validation of an execution of an upgrade. Specifically, an upgrade may be executed by executing the data upgrade files (106), and then validated by determining whether the data upgrade files were executed in an order consistent with the dependency hierarchy (108). In some embodiments, this validation makes use of an upgrade definition section that is included in each data upgrade file. The upgrade definition section contains a reference to an upgrade token (i.e., name of a functional upgrade group) corresponding to the file's functional upgrade group. When an upgrade run needs to be validated, the executed data upgrade files are collected, and each file is parsed to extract the upgrade token. This upgrade token is used to determine the correct execution phase for the file. Finally, this determined execution phase is compared to the actual execution phase in which the data upgrade file was run to determine whether it was executed in a order consistent with the dependency hierarchy.
It should be appreciated that the specific steps illustrated in FIG. 1 provide a particular method for managing upgrade dependencies according to an embodiment of the present invention. Other sequences of steps may also be performed according to alternative embodiments. For example, alternative embodiments of the present invention may perform the steps outlined above in a different order. Moreover, the individual steps illustrated in FIG. 1 may include multiple sub-steps that may be performed in various sequences as appropriate to the individual step. Furthermore, additional steps may be added or removed depending on the particular applications. One of ordinary skill in the art would recognize many variations, modifications, and alternatives.
FIG. 4 illustrates an exemplary upgrade definition section 400 for a data upgrade file. As described previously, this section is typically included in a data upgrade file to enable automated validation of a patch run. However, this section may also be used to enable other types of management functions related to an application upgrade. In the embodiment depicted, section 400 is structured in Extensible Markup Language (XML) according to a predefined XML schema. This allows section 400 to be parsed by any of a number of standard XML parsers. Alternatively, section 400 may be formatted in any other type of structured or unstructured format.
As shown, section 400 includes an attribute-value pair MODIFY NAME=“GROUP—1.” This corresponds to the upgrade token for the data upgrade file. Section 400 may also include other attributes, such as PRODUCT_FAMILY, TYPE, and the like. For example, PRODUCT_FAMILY may be used to identify a product family to which the data upgrade file belongs. TYPE may be used to distinguish metadata in section 400 that pertains to upgrade dependencies, and metadata that pertains to other types of dependencies. One of ordinary skill in the art will appreciate that many other types of attributes may be defined and included in section 400.
In addition to upgrade dependency management, embodiments of the present invention provide techniques and systems for tracking various aspects of an upgrade run. In some embodiments, these techniques and systems leverage the functional upgrade groups and dependency hierarchy described above to present various patch run metrics at a functional, rather than upgrade file, level. FIG. 5 is a simplified block diagram of an upgrade tracking system 500 in accordance with an embodiment of the present invention. Upgrade tracking system 500 may be implemented in software, hardware, or combinations thereof. For example, as software, system 500 may be implemented as part of an upgrade tracking application. Further, the software may be stored on a machine-readable medium. As hardware, portions of system 500 may be, for example, programmed into one or more field-programmable gate arrays (FPGAs) or fabricated as one or more application-specific integrated circuits (ASICs). One of ordinary skill in the art would recognize many variations, modifications, and alternatives.
As shown, system 500 includes a statistics collection component 504, execution timing component 506, status component 508, bug integration component 510, and file history component 512. In various embodiments, statistics collection component 504 is configured to collect statistics from an application database/environment after an execution of an application upgrade. These statistics may include, for example, execution timings of data upgrade files, the file version of each executed data upgrade file, and the like. Generally speaking, statistics collection component 504 is responsible for collecting the data used by other components 506, 508, 510, 512 to generate reports about an upgrade run. In one set of embodiments, this data is stored in an upgrade tracking database accessible to upgrade tracking system 500.
Execution timing component 506 is responsible for reporting execution timings related to an upgrade run. In one set of embodiments, execution timing component 506 is configured to report execution timings for individual data upgrade files. In additional embodiments, component 506 may be configured to report aggregate execution timings of data upgrade files per functional upgrade group, product family, or some other category. These aggregated timings provide insight into upgrade performance problems at a functional, rather than file, level. In various embodiments, execution timings may be reported as absolute values or as percentages of some total value (e.g., execution timing for a functional upgrade group, execution timing the entire upgrade, etc.).
Execution timing component 506 may also be configured to generate intelligent reports based on execution timing statistics. By way of example, FIG. 6 illustrates an exemplary screen display 600 generated by execution timing component 506 that shows the critical path for an upgrade run. In this context, the critical path refers to the sequence of longest-running data upgrade files from the first execution phase to the last execution phase of the upgrade. As shown, screen display 600 includes the filename of each executed data upgrade file, the phase in which it was run, the file version, and the execution timing. The longest running file for each phase is highlighted in red, thereby denoting a file in the critical path. Other types of intelligent reports and/or filters (such as the top five longest running data upgrade files, etc.) are contemplated within the scope of the present invention. One of ordinary skill in the art would recognize many variations, modifications, and alternatives.
Status component 508 is responsible for tracking one or more statuses related to an upgrade run. Generally speaking, these statuses provide information to various stakeholders as to the state of the upgrade run. As with the execution timings described above, the statuses may be tracked and reported per data upgrade file, or may be aggregated per functional upgrade group, product family, upgrade, or some other category.
In one set of embodiments, status component 508 may automatically determine status updates based on data collected by statistics collection component 504. In alternative embodiments, status component 508 may determine responsible parties that are designated to provide status updates about specific functional upgrade groups and/or data upgrade files. Status component 508 may then provide a user interface or some other mechanism to the responsible parties that enables them to enter status updates into the system.
FIG. 7 illustrates an exemplary screen display 700 generated by status component 508 that enables responsible parties to view and update various statuses for functional upgrade groups. As shown, the statuses include a success status 702, a performance status 704, and a coverage status 706. In various embodiments, success status 702 indicates whether a responsible party has manually verified successful execution of one or more data upgrade scripts in a functional upgrade group. This type of manual verification may be necessary in instances where a data upgrade file does not error-out during execution, but nevertheless fails to carry out the operations it is designed to perform. This may occur, for example, if the data upgrade file is designed to migrate data stored in a number of database tables, but fails to do anything because one of the tables is empty (perhaps due to an upstream failure).
Performance status 704 indicates whether the responsible party has performed a performance review of one or more data upgrade files in a functional upgrade group. This provides insight into the significance of the execution timings of the files. For example, if the files have already undergone a performance review, the execution timings likely represent the best possible performance for the files. However, if the files have not been reviewed for performance, their execution timings might be improved through tuning.
Coverage status 706 indicates the extent to which the application database being upgraded contains data relevant to a data upgrade file or functional upgrade group. Like performance status 704, this status provides insight into the significance of execution timings. For example, if the application database contains, little, or no, data related to a particular functional upgrade group, the execution timings of the files in that group are likely poor indicators of upgrade performance in a more typical environment that contains large amounts of data.
In various embodiments, other types of statuses related to a patch run are contemplated and within the scope of the present invention. Additionally, status component 508 may be configured to automatically log a bug against responsible parties after a patch run. This may be useful in reminding the responsible parties to provide status updates for the statuses described above.
Bug integration component 510 enables the tracking of bugs logged against a particular upgrade run. In many development organizations, bugs are logged and tracked through a dedicated bug server/database. Component 510 enables users interested in upgrade-related bugs to track the status of those bugs directly through upgrade tracking system 500.
In one set of embodiments, this integration is enabled by logging upgrade-related bugs using a predefined template identifiable by bug integration component 510. The predefined template may have various fields for bug information such as bug status, data upgrade file name, data upgrade file version, issue type, and the like. Once an upgrade has been executed, bug integration component 510 is configured to access the bug database and query bugs that include the predefined template. Component 510 may then parse each of the queried bugs to extract bug information from the predefined template. This bug information is summarized and presented to a user of upgrade tracking system 500.
In some embodiments, bug integration component 510 may store associations between bugs and data upgrade files in an upgrade tracking database of upgrade tracking system 500. Using these stored associations, bug integration component 510 may directly query a bug to receive bug updates for a specific data upgrade file.
FIG. 8 illustrates an exemplary screen display 800 showing a bug summary for an upgrade run in accordance with an embodiment of the present invention. As shown, screen display 800 includes a plurality of bug information fields including issue type, product family, file name, file version, bug status, reported date, and the like. Other types of bug information fields may also be included and are within the scope of the present invention.
File history component 512 is configured to track history information, such as execution timings, for a data upgrade file across file versions, upgrade runs, and upgrade environments. As a result, this feature can provide insight into why a file is performing poorly (or well) in a particular scenario. FIG. 9 illustrates an exemplary screen display 900 showing history information for a data upgrade file in accordance with an embodiment of the present invention. As shown, screen display 900 displays a data row for each prior execution of the file in an upgrade instance. Each data row may include history information such as the version of the file, the patch/upgrade name, the database of the upgraded environment, an execution timing, and the like. In various embodiments, this information is stored and maintained in an upgrade tracking database of upgrade tracking system 500.
In additional to the components described above, upgrade tracking system 500 may also include a database sizing component configured to track and report statistics regarding the growth of database objects as a result of the execution of an upgrade. In one set of embodiments, database sizing component is configured to report growth per individual database object (e.g., table, index, etc.). In additional embodiments, the database sizing component may be configured to report aggregate database object growth per functional group, product family, or some other category.
FIG. 10 illustrates a flowchart 1000 of the steps performed in determining database object growth in accordance with an embodiment of the present invention. In various embodiments, the processing of flowchart 1000 may be implemented in software, hardware, or combinations thereof. For example, as software, flowchart 1000 may be implemented as part of an upgrade tracking application. Further, portions of flowchart 1000 may be performed manually (i.e., through human intervention). One of ordinary skill in the art would recognize many variations, modifications, and alternatives.
At step 1002, baseline sizes for a plurality of database objects are recorded, where the baseline sizes are recorded prior to the execution of an application upgrade. In one set of embodiments, baseline sizes for all of the database objects in a database may be recorded. Alternatively, baselines sizes for only specific database objects (e.g., database objects affected by the upgrade) may be recorded.
At step 1004, upgraded sizes for the plurality of database objects are recorded, where the upgraded sizes are recorded subsequent to the execution of the application upgrade. The upgraded sizes represent the new sizes of the database objects resulting from the execution of the upgrade.
Once the baselines sizes and upgraded sizes are recorded, growth values (i.e., size deltas) for the plurality of database objects are determined (1006). If a database object has increased in size, its growth value will be positive. Conversely, if a database object has decreased in size, its growth value will be negative. In various embodiments, the growth values may be represented in absolute values (e.g., megabytes (MB), gigabytes (GB), etc.) or percentages of some total (e.g., total growth of a functional group, or of the database).
In an exemplary embodiment, the plurality of database objects are organized into one or more functional groups or product families (1008), and aggregate database object growth per functional group or product family is reported (1010). This enables users to easily see how specific functional areas and/or product families are impacted by an upgrade. This also allows software vendors to provide more informed recommendations to customers regarding the amount of extra storage space needed to consume an upgrade.
It should be appreciated that the specific steps illustrated in FIG. 10 provide a particular method for determining database object growth according to an embodiment of the present invention. Other sequences of steps may also be performed according to alternative embodiments. For example, alternative embodiments of the present invention may perform the steps outlined above in a different order. Moreover, the individual steps illustrated in FIG. 10 may include multiple sub-steps that may be performed in various sequences as appropriate to the individual step.
