CSL RM management of the IMSRSC repository

The Common Service Layer (CSL) Resource Manager (RM) interacts with the Repository Server (RS) address space to manage the stored resource definitions in the IMSRSC repository.

RM registers to the Repository Server and connects to the IMSRSC repository during RM initialization or during the UPDATE RM command processing. If RM is defined with the resource structure, RM uses the resource structure to save the repository information, such as repository name, repository type, audit access values, and the RS z/OS® cross-system coupling facility (XCF) group information. The resource structure ensures that all RMs in the IMSplex use the same repository.

You must perform system definition of the repository before RM can be started with the repository enabled. In particular, RM repository parameters are defined in the CSLRIxxx member of the IMS PROCLIB data set.

Use the UPDATE RM command to dynamically enable RM to use the repository.

Use the QUERY RM command to obtain information about the status of repositories that are being managed by the RM address space.
