Deleting the IRLM lock structure

If an IMS™ or DB2® subsystem retains a lock, restart that IMS or DB2 subsystem to clean up the locks.
It can be determined if any IMS or DB2 subsystem in the data sharing group retains a lock with the MODIFY irlmproc,STATUS,ALLD system command (where irlmproc is the IRLM associated with IMS or DB2).
Initiate® a normal shutdown of all IMS or DB2 subsystems identified with IRLM to cause IRLM to disconnect from the data sharing group.
For DB2, the IRLM is normally auto-started and will stop automatically when DB2 terminates. For IMS and for DB2 IRLMs that do not auto-stop, issue the STOP irlmproc system command.
Make sure that it terminates successfully.
Deletion of the structure might need to be forced. See Deleting structures with SETXCF FORCE for more information on forcing deletion of persistent structures with the SETXCF FORCE,STRUCTURE,STRNAME=strname system command.
