Mark the unnecessary baseline for deletion. Choose all baselines that you want deleted,
then right-click and select Delete.
The Delete dialog box displays
the selected baselines. Click Delete. The selected
baselines are now marked for deletion.
An update
operation does not select a baseline that is marked for deletion.
If your team uses project groupings, and any of the project groupings
are using marked baselines, they choose different baselines during
the update operation.
The CM administrator sets
up the Save Offline and Delete command. The command automatically
deletes baselines that are marked for deletion when they are no longer
used. For details, see the save_offline_and_delete
command.
Your site might decide to inactivate
the release you have finished. Use the Deleting cache files to clean out the process
rules and any old releases from the release.
Retaining
the extra releases and process rules does not cause problems. Clean
up is for convenience. Cleaning out the releases and the process rules
makes it easier to find relevant information in corresponding dialog
boxes.
Additionally, you cannot delete a baseline
while a project grouping uses that baseline, or while a process rule
uses the baseline. If you try to delete a baseline and its checked-in
projects and products, and one or more of its associated projects
or products is a member of a project that is not part of the baseline,
the delete baseline operation succeed. However, the projects or products
are not deleted. Furthermore, if projects in the baseline are members
of another baseline, or are baseline projects, the delete operation
is successful, but the projects are not deleted.
Remove
obsolete project hierarchies, and then resulting empty project groupings,
before you can delete old baselines. However, empty project groupings
might still carry important information about tasks the owner explicitly
added to or removed from that grouping.
To find
and remove empty project groupings that also have no explicitly added
or removed tasks, use the following commands:
ccm
set role ccm_admin
ccm query
–t project_grouping "is_no_project_grouping() and has_no_added_task_in_pg()
and has_no_removed_task_in_pg()"
