Because a Rational ClearCase community is defined in part by use of a common registry, the registry server host is usually the first computer in the community on which Rational ClearCase is installed. The Rational ClearCase installation program automates most of this process, and by installing or upgrading the registry server host first, you simplify the process of installing and configuring other hosts in your Rational ClearCase community.
A Rational ClearCase registry server does not have to be configured with support for local VOBs and views, although most communities can designate a VOB or view host as a registry server without degrading overall performance.
The procedure for converting an existing Rational ClearCase host to a registry server depends on the host platform type.
