      • 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 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.

        • Overview of replica creation

          You can use a three-phase procedure to create a new replica: export, transport, and import.

        • Replica-creation scenario for a VOB

          To define an example scenario, let's say that a company’s software development takes place in Boston, Massachusetts and in a new development office in San Francisco, California.

        • Replicating a VOB between Windows® and another platform

          When setting up replicas on Windows® and other platforms (specifically Linux® and the UNIX® system) at different sites, there are configuration issues that must be addressed.

      • 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.
