- Introduction
and Rational® ClearQuest® MultiSite add a powerful capability to and Rational® ClearQuest®. With MultiSite, developers at different locations can use the same versioned object base (VOB) or Rational® ClearQuest® database set (a schema repository and its associated user databases). 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 Code ClearCase®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.
