Creating MSC resource definitions in the IMSRSC repository

You can create MSC resource definitions in the IMSRSC repository for one or more new or existing IMS systems in your IMSplex by using the IMS type-2 CREATE commands.

1. Issue the CREATE command for the type of MSC resource that you want to create.
   You must create MSC resources in the following order for the MSC link to be usable:

   1. CREATE MSPLINK
   2. CREATE MSLINK
   3. CREATE MSNAME
   4. CREATE LTERM

   The CREATE command must be issued to each IMS in each IMSplex for which the resource definitions are to be exported to the repository. You can use the ROUTE keyword on the OM API to specify the IMS to which the command is routed.

2. Specify AUTOEXPORT=AUTO or REPO in the DYNAMIC_RESOURCES section of the DFSDFxxx member in the IMS PROCLIB data set.
   At the next IMS checkpoint, the MSC resource definitions that you created since the last automatic export are automatically exported to the IMSRSC repository. The IMS checkpoint can be initiated either by issuing the /CHECKPOINT command or automatically by the IMS system.

   If you use the /CHECKPOINT command to initiate an IMS checkpoint, the command must be routed to each IMS in each IMSplex in which the MSC resources are defined.
