IMS ID information in the IMSRSC repository

When resource definitions are added to the IMSRSC repository, along with the resource definitions and the IMS resource lists, the IMS ID information is also maintained in the IMSID member table. This table keeps track of all the IMS IDs that are defined to the IMSRSC repository.

When the resource definitions are deleted from the IMSRSC repository, the IMS ID information is still in the IMS ID member table. When a subsequent EXPORT DEFN TARGET(REPO) SET(IMSID(*)) is issued or autoexport is done when AUTOEXPORT_IMSID=ALL is issued, the resource definitions are written for all the IMS IDs in the member table.

When an IMS is leaving the IMSplex or when an IMS ID is added to the IMSRSC repository in error, the IMS ID information can be deleted from the IMSRSC repository using the DELETE DEFN TARGET(REPO) TYPE(IMSIDMBR) command.
