Oracle Enterprise Manager Getting Started with the Oracle Standard Management Pack Release 9.0.1 Part Number A88749-02 |
|
The Change Manager application is the change management central interface. Change Manager gives you direct or indirect access to all of the change management 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).
You can run Change Manager connected to an Oracle Management Server or not connected to an Oracle Management Server. When you run Change Manager without connecting to an Oracle Management Server, you are running Change Manager standalone.
When you run Change Manager connected to an Oracle Management Server:
When you run Change Manager standalone:
A standalone repository is required to store Change Management Packchange management objects created during a standalone change management session. Read and follow the steps to perform before creating a standalone repository in the Oracle Enterprise Manager Configuration Guide.
The next time you start Change Manager standalone, a repository login dialog box prompts you for the Username, Password, and Service credentials of the user that owns the schema to be used for your standalone repository. When you provide the credentials for that user, the standalone repository tables needed by the change management applications will be created for you in that user's schema.
At some point after creating a standalone repository for change management objects created during your change management sessions, you might decide that you want to use a different standalone repository.
To start using a different standalone repository, you must:
Removing these lines from ClientConfig.properties removes information about the current standalone repository that is being used for standalone change management objects.
Change Manager uses the information in the ClientConfig.properties file to determine the standalone repository in which to store information from your change management session.
You can start the Change Manager application in any of the following ways:
When Change Manager is started from the Console using any of these methods, the mode in which the Console is running (connected to the Oracle Management Server or standalone) determines the mode in which Change Manager will run.

When you start Change Manager using this method, you are prompted whether you want to run Change Manager connected to the Oracle Management Server or standalone.
When you start Change Manager using this method, you are prompted whether you want to run Change Manager connected to the Oracle Management Server or standalone.
See "Starting Change Management Applications from Change Manager" for more information on starting the other change management applications from Change Manager.
The Change Manager main window has a navigator tree on the left and a detail view on the right.
When Change Manager is running connected to an Oracle Management Server, the navigator tree displays the following change management objects, organized by owner:
The tree contains the Baselines and Comparisons folders, even if objects of these types have not been created yet.
If Change Manager is running standalone, the tree displays only the change management objects belonging to the owner of the standalone repository being used.
If the Change Manager navigator tree contains no objects, this means that no baselines or comparisons have been created in the repository. When you create these objects, they appear in the Change Manager tree.
When you select a change management 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, the detail view to the right of the Change Manager tree provides information about change management 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 change management applications and viewers from Change Manager, as follows:
Choose Object->Create Baseline.
Choose Object->Compare Database Objects.
Expand the Change Manager folder, user folder, and Baselines folder in the Change Manager tree, select a baseline, then choose Object->View Baseline.
Expand the Change Manager folder, user folder, and Comparisons folder in the Change Manager tree, select a comparison, then choose Object->View Comparison.
You can also start a change management application by clicking the Change Manager toolbar icon for that application.
When you start a change management application from Change Manager, the mode in which Change Manager is running (connected to the Oracle Management Server or standalone) determines the mode in which the other change management application will run.
Table 6-1 describes how to use Change Manager to perform different types of baseline operations.
For more information on working with baselines, see:
Table 6-2 describes how to use Change Manager to perform different types of comparison operations.
For more information on working with comparisons, see:
You can view history entries that show the status of the following change management tasks:
By viewing the history entries for completed tasks, you can determine when each change management task was performed and its completion status.
To view the history entries for tasks in the current change management 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 completed tasks.
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 change management tasks that have been completed. Each row on the History page is a history entry for one completed task. 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 6-3:
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.
By default, when you select a 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 change management window or click Remove to remove the selected version of the object from the Oracle Enterprise Manager repository.
Note: When you remove a version of a baseline or comparison, the version numbers for the remaining versions of that object remain the same. |
You can export and import 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.
To export baselines or comparisons:
To import baselines or comparisons:
