Rebasing a UCM stream using Default Rebase

Rebase a UCM stream to update a UCM view with the set of versions selected by the parent stream's recommended baselines, or with a set of versions in baselines that you choose.

1. In the ClearTeam Navigator, select the ClearCase® view (typically a UCM development view) in which you want to do the rebase operation. If you are working in the Eclipse environment, use any Eclipse view that supports the Team context menu and select a resource whose view is attached to the stream you want to rebase.
2. Right-click the view and select Rebase > Default Rebase from the context menu in the ClearTeam Navigatoror click the Rebase icon on the ClearCase UCM toolbar and select Default Rebase.
3. Specify rebase options in the dialog box and then click OK. Note that you can also set these options beforehand by selecting Window > Preferences in the Eclipse Workbench, then selecting Team > IBM® ClearTeam® Explorer > Integration > Rebase and Deliver in the Preferences dialog box. If you have set these options beforehand, the Default Rebase dialog does not appear when you select Rebase > Default Rebase; instead, the rebase operation begins.
4. Click OK to start the rebase.
   If the stream is currently up-to-date with respect to the recommended baseline, Rebase Stream displays an informational dialog box stating that no rebase is needed.
5. The versions in the selected baseline are merged to the development view. Any manual merges that are required are listed in the Rebase Results view with a Merge Status of Needs Merge.
   Click the icon on the Rebase Results view toolbar to start merging. This opens the first item in the list with the appropriate manual merge tool. When the first item is merged, the next item is opened in the appropriate merge tool. This process continues until all required merges are complete or you click the icon to stop merging.

   Note: To cancel the rebase and undo any merges that have completed, click the icon on the Rebase Results view toolbar.
6. After completing any required merges, build and test in the development view.
7. If the build and test are successful, click the icon on the Rebase Results view toolbar to complete the rebase operation.
