Common Access Repository Manager (CARMA)
Common Access Repository Manager (CARMA) is a server platform for Repository Access Managers (RAMs). A RAM is an Application Programming Interface (API) for a z/OS® based Software Configuration Manager (SCM). By wrapping the SCM functionality in a RAM, a single API is available for a client to access any supported SCM.
Developer for z/OS provides multiple pre-built RAMs and source code examples for creating your own RAM.
SCMs that are based on host systems need single-user address spaces to access their services, which requires CARMA to start a CARMA server for each user. It is not possible to create a single server supporting multiple users.
