  - Introduction
    DevOps Code ClearCase® MultiSite and add a powerful capability to DevOps Code ClearCase and . With MultiSite, developers at different locations can use the same DevOps Code ClearCase versioned object base (VOB) or . For DevOps Code ClearCase, each location (site) has its own copy (replica) of the VOB. 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.
  - MultiSite operation
  - Implementation planning
    Before you install and use DevOps Code ClearCase® MultiSite, you need to plan your implementation.
    - MultiSite installation
      MultiSite is installed as an optional product component during the DevOps Code ClearCase® installation.
    - MultiSite licensing
      A MultiSite license is required to access an object in a replica by a MultiSite command or GUI, by a DevOps Code ClearCase® command or GUI, or by a standard operating system command.
    - Shipping server use with DevOps Code ClearCase® and Rational® ClearQuest®
      If you use both DevOps ClearCase® MultiSite and DevOps ClearQuest® MultiSite, you use the same shipping server for both products. The shipping server is installed when you install DevOps ClearCase MultiSite.
    - DevOps Code ClearCase® use model
      Before development work is started in any VOB, the project manager and administrator must define the DevOps Code ClearCase® use model. For example, the project manager must specify the branches, labels, and triggers that are used for development and integration work.
    - MultiSite use model
      There are different aspects of your MultiSite use model that affect the implementation and deployment of a MultiSite environment.
    - Responsibilities of MultiSite administrators
      The MultiSite administrator must perform the tasks described in this topic.
  - MultiSite command set
    This section summarizes the commands for DevOps ClearCase® MultiSite and DevOps ClearCase that display DevOps Code ClearCase MultiSite information.
  - 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.
  - Feature levels
    Feature levels allow different replica hosts in a VOB family to run different versions of DevOps Code ClearCase®. You can raise the feature level of either a single replica host or an entire VOB family.
  - Creating VOB replicas
    Before creating a replica, you must make decisions about branching, mastership, identities and permissions preservation, and method of packet delivery.
  - Replica synchronization
    Replica synchronization uses the same export-transport-import procedure that is used during replica creation.
  - Administering replicas
  - Using MultiSite for VOB backup and interoperability
    You can use DevOps Code ClearCase® MultiSite to back up a VOB and to provide access to VOBs in a heterogeneous network.
  - Troubleshooting MultiSite operations
    When you encounter a situation where running a DevOps Code ClearCase® MultiSite command produces an unexpected result, or produces a warning or error message, the information in this section can assist you in troubleshooting the problem.

Glossary

MultiSite licensing

A MultiSite license is required to access an object in a replica by a MultiSite command or GUI, by a DevOps Code ClearCase® command or GUI, or by a standard operating system command.

You calculate the number of MultiSite licenses that you need by determining how many developers will access replicated VOBs. If all developers will access these VOBs , then you need the same number of DevOps Code ClearCase® MultiSite licenses as DevOps Code ClearCase® licenses. If some developers will not access replicated VOBs, then you can purchase fewer MultiSite licenses.

For example, a company has two sites, with 20 developers at site A and five developers at site B. The company has three VOBs at site A; two are replicated to site B and one is not replicated. Five developers at site A access only the unreplicated VOB ; the other 15 work in all VOBs . The five developers at site B work in the replicated environment. Therefore, the company purchases the following number of licenses:


Site	Number of DevOps Code ClearCase® licenses	Number of MultiSite licenses
A	20	15
B	5	5

Attention: This example assumes that you purchase one DevOps Code ClearCase® license for each developer. If you have fewer DevOps Code ClearCase® licenses than developers, you can purchase a proportionate number of MultiSite licenses. For example, if the company purchased three DevOps Code ClearCase® licenses for site B, it would also purchase three MultiSite licenses for site B.
