The Rational® ClearCase® registry provides a central repository of information about VOB and view locations, default values for various host Rational ClearCase settings, and other information that a Rational ClearCase community shares. Every Rational ClearCase host is assigned to (is a client of) a single registry server host. The registry server host can be any computer on which Rational ClearCase is installed.
A Rational ClearCase community is defined in part by use of a common registry. If the registry server host becomes unavailable or registry data becomes corrupted, users cannot access artifacts under Rational ClearCase control. For the most part, registry data is created, modified, and removed automatically, but there are some cases where administrative intervention may be required.
See Administering the Rational ClearCase registry for more information about the Rational ClearCase registry.
