Creating or updating MSC resources in the repository

You can create or update MSC resources in the IMSRSC repository for the IMSplex.

Before you create or update MSC resource definitions in the IMSRSC repository, ensure that the following prerequisites are met:
  • The IMSRSC repository is defined.
  • Dynamic resource definition for MSC resources is enabled.
  • The IMSRSC repository is enabled for MSC resources.
  • AUTOEXPORT=AUTO or REPO is specified in the DYNAMIC_RESOURCES section of the DFSDFxxx member of the IMS PROCLIB member.
  • MODBLKS=DYN is specified either in the COMMON_SERVICE_LAYER section of the DFSDFxxx PROCLIB member or in the DFSCGxxx member of the IMS PROCLIB data set.

To create or update MSC resources in the repository for the IMSplex:

Procedure

  1. Create or update MSC resources locally at the IMS system by using the appropriate CREATE or UPDATE command.
    At the next IMS checkpoint, the MSC resource definitions that you created or updated since the last automatic export are exported to the IMSRSC repository. The IMS checkpoint can be initiated either by issuing the /CHECKPOINT command or automatically by the IMS system.
  2. For remote transactions and transaction descriptors, you can issue the EXPORT DEFN TARGET(REPO) command, which defaults to the SET(IMSID()) keyword, to route the command to the IMS system whose resource definitions are to be exported.
  3. Repeat these steps at each IMS system where the MSC resource definitions are, or will be, defined. The repository will maintain the attributes of the MSC resources for each IMS.
