CM Server deployment models

CM Server is a J2EE application that runs within a WebSphere® Application Server Java™ process. The ClearCase® and ClearQuest® RPC servers must be on the same machine as WebSphere Application Server. You can install the traditional ClearCase servers (VOB and registry servers) and the ClearQuest database servers on another host but Rational® ClearCase and Rational ClearQuest must be installed on all machines on which RPC servers are running. Some sites might need to access CM Server by proxy or redirection from another WAN server (for example, if CM Server is deployed in a distributed environment or in an environment that includes more than one server machine.)

There are differences between installing CM Server into an existing WebSphere Application Server instance and creating a new WebSphere Application Server instance during the installation.

Two or more WebSphere Application Server profiles can exist on a system (for example, one for a RequisitePro® integration and one for CM Server). On Windows®, CM Server and other WebSphere Application Server profiles may all use the same WebSphere Application Server installation, and each profile is deployed under its own profile location. For example:
  • cmprofile for CM Server is deployed under common/CM/profiles/cmprofile
  • profile1 for ProjectConsole™ is deployed under common/EmbeddedExpress/profiles/profile1
  • profile2 for RequisitePro Web is deployed under common/EmbeddedExpress/profiles/profile2
Each profile corresponds to its own JVM instance that runs on the machine (and for Windows systems, corresponds to a Windows service).
