CSL RM administration

The tasks associated with administering the Resource Manager (RM) are typically performed by the system administrator or system operator.

Information managed by the CSL RM
You can use the Resource Manager (RM) to create, update, query, or delete resources in the resource structure.
Resource structure duplexing requirements for CSL RM
CQS does not log resource updates or support a checkpoint of the resource structure. However, CQS supports automatic duplexing of the resource structure for backup in case of structure failure.
How the CSL RM repopulates a resource structure
If the resource structure and its duplex (if applicable) fail, and CQS can allocate a new structure, CQS notifies RM to repopulate the structure. RM repopulates the structure from information in its local control blocks.
How z/OS rebuilds a resource structure
Resource structures are defined with system-managed rebuild, so z/OS® automatically rebuilds the structure when no CQS is up to build the structure. z/OS cannot rebuild the structure if the structure fails or if z/OS loses connectivity to the structure.
