DFS4448A RM RESOURCE STRUCTURE USAGE MISMATCH
Explanation
When IMS registers with a Resource Manager (RM) during IMS initialization or when an RM joins the IMSplex, IMS is informed whether RM is using a resource structure or not. Afterward, message DFS4448A is issued if RM changes the resource structure usage.
System action
Online processing continues. IMS does not change its use of the resource structure. If IMS was not using a resource structure, it ignores the new resource structure. If IMS was using a resource structure, limited terminal processing continues. However, no new terminals or users are allowed access to IMS, and certain processes (including IMS shutdown) hangs until a resource structure is enabled.
If a /NRESTART or /ERESTART command was processing (other than COLDCOMM or COLDSYS), and IMS issues message DFS4448A, IMS abends with 0233.
Operator response
Determine if RM was started properly; if not, terminate RM and restart it. Otherwise, terminate IMS and cold start TM so the resource structure change will be recognized by TM.
