Managing registry data

Registry data for most common operations is managed automatically. Other operations can require an administrator to create, remove, or modify registry data.

An object and a tag are created by Rational® ClearCase® when you create a VOB or a view. The tag and the object are removed when you remove a VOB or a view. In many cases, no further administrative action is required. You might need to manipulate VOB and view objects and tags for any of the following reasons:

To make a tag available in another registry region
To change the name of a VOB or view
After you move a VOB or view to a different host
After you restore a VOB or view from backup media
To clean up the registry after a VOB or view is removed by a nonstandard procedure

To inspect, create, and repair VOB and view objects and tags, use the ClearCase Registry node of the Rational ClearCase Administration Console or any of the cleartool subcommands named in Figure 1, which shows how these commands affect registry data.

Figure 1. How cleartool commands affect registry data

Figure 3 shows how cleartool commands add and remove view tag and VOB tag data and view object and VOB object data from the registry.

Viewing objects and tags
Objects and tags include a variety of information that can be used to diagnose access problems to VOBs and views.
Registering a VOB or view
Registering a VOB or view creates a new object in the registry or replaces an existing one.
Creating, removing, or changing tags
Tags are typically created, removed, or modified when you rename a VOB or view or change its network access information.
Changing site defaults
Site defaults are typically established during site preparation but can be modified later if necessary.
Adding a Rational ClearCase registry region
Adding a Rational ClearCase registry region requires you to create the region, add hosts to it, and populate the region with tags.
Creating additional tags for VOBs and views in a Rational ClearCase registry that has regions
Any process that creates a VOB or view also creates the object and the initial tag. If additional tags are needed, use the mktag command to create them.
Removing a registry region
You can remove an unneeded registry region after reassigning its clients to a different one.
Renaming a registry server host
When you rename a registry server host, you must reconfigure all of its clients to use the new name.
