It is possible that a user server address space terminated without first doing clean-up in the user administration control structures. This can happen if the address space was forced (MVS FORCE command) and no address space related clean-up ran. In this case the command:
F <scheduler>,TSO,DELETE,USER=userid
enables unconditional removal of the TSO user ID from the user administration control structures to free the entries and the port the user server address space was listening on. The CMDTASK DD statement of the scheduler address space shows:
SLR0039W 13:53:19.557 User USERID deleted.
If the specified user is not found in the user administration control structures, the following message is issued:
F <scheduler>,TSO,DELETE,USER=ALL SLR0038W 13:53:08.239 User ALL not found. Delete command ignored.
+SLR0092E 14:11:40.508 User servers with Timeout_Action=STOP must be started with POLICY=1 (Started Jobs). Timeout is ignored.
