Creating runtime resource and descriptor definitions in an IMSplex with the CREATE command

If you have a mixture of DRD-enabled and DRD-disabled IMS systems in an IMSplex, you can create resource or descriptor definitions for this environment.

1. Perform an online change process for the IMS.MODBLKS data set on the IMS systems that have not migrated to DRD.
2. Issue CREATE commands for the resource or descriptor definitions you want to create on the IMS systems that have DRD enabled.
