Importing resource and descriptor definitions from the IMSRSC repository by using the IMPORT command

You can import resource and descriptor definitions from the IMSRSC repository to IMS by issuing the IMPORT DEFN SOURCE(REPO) command.

1. Issue the IMPORT DEFN SOURCE(REPO) command.
   You can use the keyword SCOPE(ALL) or SCOPE(ACTIVE) to specify whether the command applies to all IMS systems in the IMSplex that have the resource defined (even if some of them are inactive) or only to the active systems.

   If SCOPE(ALL) is specified and an IMS system to which the resources and descriptors are defined is not active, the command master IMS calls RM to create or update an IMS change list in the repository with a list of the resource and descriptor names being imported. The resource definitions of all the resource names in the IMS change list are imported at warm or emergency restart so that the IMS is synchronized with all other IMS systems in the IMSplex. If a change list is created in the repository, a response line is returned on the IMPORT command for each resource name in the change list with the IMSID of the IMS for which the change list is created, along with the import type (IMPTYPE) of the change list.

   Use the OPTION(UPDATE) keyword for the command to indicate that if the definition being imported is for a resource or descriptor that exists in IMS, the imported definition replaces the existing runtime resource or descriptor definition. If the definition being imported is for a resource or descriptor that does not exist, the keyword indicates that the imported definition is used to create the runtime resource or descriptor definition. If the OPTION(UPDATE) keyword is not specified and a runtime definition exists for the resource or descriptor, the import of the resource or descriptor definition fails.

   The internal control blocks used to manage the resources are either created or updated during IMPORT DEFN SOURCE(REPO) command processing.

   You can verify the IMPORT DEFN SOURCE(REPO) command output.
2. If there was an error from running the IMPORT DEFN SOURCE(REPO) command, verify whether the changes have been imported by using one of the QUERY commands to ensure that resources are imported.
