DevOps Code ClearCase® product family hosts

Every host in a DevOps Code ClearCase® network plays one or more of the following roles.
  • Client host. Each DevOps Code ClearCase® user works at a client host, running command-line programs and graphical user interfaces, and other software (for example, development tools and operating system utilities). A client installation can include the multiversion file system (MVFS), which provides file-system support for dynamic views.
  • Server host. Any host on which a DevOps Code ClearCase® data repository can be created is a server host. Some hosts might be dedicated servers on which client software rarely runs (and might not be installed). Other server hosts might also be clients.
  • License server host. Every DevOps Code ClearCase® community must have a license server host, which is normally designated during site preparation. The license server supplies licenses that allow DevOps Code ClearCase® commands to run. Each client or server host in the community is initially associated with a license server during installation. License servers and license administration contains more information about the license server and license administration.
  • Registry server host. Every DevOps Code ClearCase® community must have a registry server host, which is normally designated during site preparation. The DevOps Code ClearCase® registry provides a way for members of the community to locate shared resources, such as data repositories. Each client or server host in the community is associated with a registry server during installation. For more information about the DevOps Code ClearCase® registry and the registry server host, see Administering the DevOps Code ClearCase registry.
  • CCRC WAN server host. At least one host in the network acts as the CCRC WAN server host. The CCRC WAN server provides application support for the DevOps Code ClearCase® Remote Client.
  • Network-attached storage (NAS) devices. These devices can be used to store any DevOps Code ClearCase® programs or data. NAS devices do not run DevOps Code ClearCase®; they provide storage that DevOps Code ClearCase® hosts access over a local area network. For information about configuring access to a certified NAS device, see DevOps Code ClearCase and network-attached storage devices.
  • Non-ClearCase® hosts running Linux or the UNIX system. Hosts running Linux or the UNIX system that cannot run DevOps Code ClearCase® can access DevOps Code ClearCase® data, with limitations, through standard network file-system facilities. For more information, see Configuring non-ClearCase access on Linux or the UNIX system.
