- Introduction
DevOps Code ClearCase® MultiSite and Rational ClearQuest MultiSite add a powerful capability to DevOps Code ClearCase and Rational ClearQuest. With MultiSite, developers at different locations can use the same DevOps Code ClearCase versioned object base (VOB) or Rational ClearQuest database set (a schema repository and its associated user databases). For DevOps Code ClearCase, each location (site) has its own copy (replica) of the VOB. For Rational ClearQuest, each location has its own copies, or replicas, of the schema repository and user databases. At any time, changes made in one replica can be sent in update packets to other replicas. You can manage replicas by using the command-line tools. - Implementation planning
Before you install and use DevOps ClearQuest MultiSite, you need to plan your implementation. - Packet transportation methods and configuration
The method you choose for transporting packets between replicas depends on connectivity. If your replicas do not have IP connectivity, you must use a file-based transport method. If your replicas have connectivity, you can use the store-and-forward facility. - Database replica creation
Creating your database replicas requires careful planning and consideration part of which involves making decisions about mastership and methods of packet delivery. - Replica synchronization
Replica synchronization uses the same export-transport-import procedure that is used during replica creation. - Database replicas administration
Sustaining a smoothly functioning MultiSite environment requires dedicated administration. Many administrative processes can drastically change your environment and require careful consideration and planning. - Mastership management
The management of mastership affects how database objects are accessed and manipulated by users in your MultiSite environment. Mastership management is an ongoing process as new objects are entered into the database and users' requirements change. - Troubleshoot MultiSite operations
There are common situations in which running a Rational ClearQuest MultiSite command produces an unexpected result, sometimes accompanied by a warning or error message. - MultiSite command set
There are a series of MultiSite commands and API functions that display or modify MultiSite information.
