Oracle(R) Enterprise Manager Getting Started with Oracle(R) Change Management Pack Release 2.1 A76919-01 |
|
The Change Manager application is the Oracle Change Management Pack central interface. Change Manager gives you direct or indirect access to all of the Oracle Change Management Pack operations (in cases where Change Manager cannot directly perform an operation, such as capturing or comparing object definitions, Change Manager starts the application that performs that operation).
Change Manager provides access to all the Oracle Change Management Pack objects owned by all users, and allows appropriate operations on these objects depending on ownership.
Objects are ordered by owner in the Change Manager navigator tree. Each user has read and write access to the object definitions that he or she owns, and has read-only access to object definitions owned by other users.
You can start the Change Manager application in any of the following ways:
See "Starting Change Management Pack Applications from Change Manager" for more information on starting the other Change Management Pack applications from Change Manager and "Starting DBA Studio from Change Manager" for more information on starting DBA Studio from Change Manager.
The Change Manager main window (see Figure 2-1) has a navigator tree on the left and a detail view on the right.
The navigator tree displays the following Oracle Change Management Pack objects, organized by owner:
If the Change Manager navigator tree contains no objects, this means that no change plans, baselines, or comparisons have been created in the Oracle Enterprise Manager repository that Change Manager is connected to. When you create these objects, they appear in the Change Manager tree.
When you select a Change Management Pack object or object folder and click the right mouse button, a context menu is displayed that lists the operations that can be performed in the current context. If you select an object that you do not own, some of the operations on the context menu are unavailable (for example, you cannot remove or modify an object that you do not own, because you have read-only access to objects owned by other users). On the context menu, choose any available operation that you are interested in performing.
When the Change Manager Users folder (the root of the Change Manager tree) is selected (as in Figure 2-1), the detail view provides information about Oracle Change Management Pack applications and the operations that they can perform. Click on an application's icon in the detail view to learn more about the operations that the application can perform.
When other folders or objects are selected in the Change Manager tree, the detail view provides related information about the selected folder or object.
You start the other Oracle Change Management Pack applications from Change Manager, as follows:
Expand the Change Manager folder, user folder, and Baselines folder in the Change Manager tree, select a baseline, then on the Object menu, click View Baseline.
On the Change Manager Tools menu, click DB Alter.
On the Change Manager Object menu, click Create Baseline.
On the Change Manager Object menu, click Compare Database Objects.
On the Change Manager Tools menu, click DB Propagate.
On the Change Manager Tools menu, click Find Database Objects.
On the Change Manager Tools menu, click DB Quick Change.
On the Change Manager Object menu, click Create Change Plan, then in the Create Change Plan Options dialog box, click Create Change Plan Manually.
In some cases, you may want to start DBA Studio to quickly create or modify object definitions. To start DBA Studio from Change Manager, on the Tools menu, click DBA Studio.
Table 2-1 describes how to use Change Manager to perform different types of baseline operations.
For more information on working with baselines, see:
Table 2-2 describes how to use Change Manager to perform different types of comparison operations.
For more information on working with comparisons, see:
Table 2-3 describes how to use Change Manager to perform different types of change plan operations.
Operation | Steps for Performing the Operation |
---|---|
Create a new change plan |
On the Object menu, click Create Change Plan. Then in the Create Change Plan Options dialog box, select the name of the application that you want to use to create the change plan (the Create Manually option lets you use Plan Editor to create the plan). See Chapter 3, "Using Plan Editor" for more information on using Plan Editor to create a change plan. |
View and modify a change plan |
Select the change plan in the tree. On the Object menu, click Edit Change Plan. This lets you view and modify the change plan using Plan Editor. See Chapter 3, "Using Plan Editor" for more information on using Plan Editor to edit and modify a change plan. |
Delete a change plan |
Select the change plan in the tree. On the Object menu, click Remove. This deletes all versions of the change plan. |
Rename a change plan |
Select the change plan in the tree. On the Object menu, click Edit Change Plan. On the General page for the plan in Plan Editor, edit the name of the plan, then click one of the folders in the Plan Editor tree. When the new plan name appears in the Plan Editor tree, exit Plan Editor. On the Change Manager View menu, click Refresh to see the plan's new name displayed in the Change Manager tree. |
Export a change plan to a file |
On the Change Manager Tools menu, click Export Plans/Baselines/Comparisons, then specify the change plan to export and the name of the export file. |
Import a change plan from a file |
On the Change Manager Tools menu, click Import Plans/Baselines/Comparisons, then specify the name of the export file and the change plan to import. |
Create a new version of a change plan |
None. Oracle Change Management Pack automatically creates a new version of a change plan when necessary to ensure that the history features for the change plan work properly. |
View a previous version of a change plan |
Select the change plan in the tree. On the Change Manager Object menu, click Show Versions. In the Versions dialog box, click the version you want to view, then click View. |
Delete a previous version of a change plan |
Select the change plan in the tree. On the Change Manager Object menu, click Show Versions. In the Versions dialog box, click the version you want to delete, then click Remove. |
View history entries for change plan tasks |
On the View menu, click Show History. In the History dialog box, view history entries for pending plan tasks on the Pending page and view history entries for completed plan tasks on the History page. |
For more information on working with change plans, see:
You can view history entries that show the status of the following Oracle Change Management Pack tasks:
By viewing the history entries for pending tasks and completed tasks, you can determine when each Oracle Change Management Pack task was performed and its completion status.
To view the history entries for tasks in the current Oracle Change Management Pack repository, on the Change Manager View menu, choose the Show History option, which displays the History dialog box. The History dialog box allows you to view both pending tasks and completed tasks.
Click the Pending tab of the History dialog box to view pending tasks. Pending tasks are script executions that need to be kept or undone. See "Executing the Script with Plan Editor" for more information on keeping or undoing the changes made by a change plan script.
The history entries on the Pending page of the History dialog box enable you to keep track of the Oracle Change Management Pack pending tasks, which need further attention. Each row on the Pending page is a history entry for one pending task.
When you complete a pending task and refresh the History dialog box, the entry is moved to the History page. You also have the option of manually moving an entry for a pending task to the History page.
On the Pending page, you can perform the operations shown in Table 2-4:
You are notified of any pending tasks on the Pending page and are given the opportunity to complete them each time you exit Change Manager.
Click the History tab of the History dialog box to view completed tasks.
The history entries on the History page of the History dialog box enable you to track the Oracle Change Management Pack tasks that have been completed or that have been manually moved from the Pending page to the History page. Each row on the History page is a history entry for one completed task or a pending task that was manually moved from the Pending page. The status for a particular history entry tells you whether the task completed successfully or not.
On the History page, you can perform the operations shown in Table 2-5:
After you create a baseline specification, you can use the specification to generate multiple baselines over time. Similarly, after you create a comparison specification, you can use it to generate multiple comparisons over time. New versions of a change plan are created automatically when necessary to ensure that the history features for change plans work properly.
By default, when you select a change plan, baseline, or comparison in Change Manager, any operations you perform are carried out on the latest version of that object. In some cases, however, you may want to view or remove an earlier version of the object. To do so, after you select the object in Change Manager, on the Object menu, click Show Versions. This displays the Versions dialog box. In the Versions dialog box, select the version of the object that you are interested in, then click View to view the selected version of the object in the appropriate Oracle Change Management Pack window or click Remove to remove the selected version of the object from the Oracle Enterprise Manager repository.
You can export and import change plans, baselines, and comparisons using Change Manager. After you export one or more of these objects to a file, you can then import the objects into another repository, which copies the objects from one repository to another.
