Administering Rational ClearQuest MultiSite
- Introduction
IBM® Rational® ClearCase MultiSite® and IBM Rational ClearQuest® MultiSite add a powerful capability
to IBM Rational ClearCase® and Rational ClearQuest.
With MultiSite,
developers at different locations can use the same Rational ClearCase
versioned object base (VOB)or Rational ClearQuest database set (a
schema repository and its associated user databases).
For Rational 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 using either the command-line tools
or the Global Monitor feature, which includes its own help system.
- Implementation planning
Before you install and use Rational 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.
