Administering the Rational ClearCase registry

Because it is a distributed application, Rational ClearCase provides a way for users to access shared resources without knowing host names, network paths, or the other information usually required to locate and access a network resource. In addition to information about VOB and view locations, the Rational ClearCase registry stores default values, established by an administrator, for typical client host settings.

Every Rational ClearCase host is assigned to (that is, is a client of) a single registry host. The registry server host is typically specified during the site preparation process and can be any computer on which Rational ClearCase is installed. Clients use remote procedure calls (RPCs) to communicate with the registry server. These RPCs request information from the registry as needed and modify registry data when VOBs or views are created or moved or when community defaults are changed.

• Registry data
  An understanding of the registry data model is important for many administrative procedures.
• The registry server host
  The Rational ClearCase registry is an integral part of most Rational ClearCase operations, so the registry server host must be stable, available, and accessible to all hosts in the network.
• Guidelines for using multiple Rational ClearCase registries
  You can configure multiple Rational ClearCase registries if you need to limit VOB and view access to specific clients.
• Assigning a Rational ClearCase host's registry and region
  Use this procedure to assign a Rational ClearCase host to a new registry server, a new registry region, or both.
• 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.
• Registry administration guidelines
  Ensuring the integrity of registry data is an essential task for any Rational ClearCase administrator.
• Rational ClearCase registry backup and switchover
  Rational ClearCase provides tools that enable you to configure one or more backup registry hosts. A backup registry host can take over when a registry server fails.
