MODIFY STOP `irlmproc` (z/OS IRLM),ABEND command (z/OS IRLM)

The MODIFY irlmproc, ABEND command terminates IRLM abnormally. IRLM processes this command even if a Db2 subsystem is identified to it.

Abbreviation: F

Environment

This command can be issued only from a z/OS® console.

Data sharing scope: Member

Authorization

The command requires an appropriate level of operating system authority.

Syntax

Option descriptions

Parameters must be separated by commas with no spaces.

irlmproc: Specifies the procedure name of the IRLM that is to be terminated.
DUMP: Specifies that IRLM is to terminate abnormally with a U2020 abend. A system dump is taken to the SYS1.DUMPxx data set. IRLM does not deregister from ARM.
NODUMP: Specifies that IRLM is to FORCE the DBMS off and terminate normally without generating a dump. All DBMS work is quiesced and IRLM stops itself. NODUMP requires that IRLM be functioning normally. Do not use this option if IRLM appears to be hung.
A second invocation causes IRLM to terminate abnormally with a U2020 abend; no dump is taken.

Usage notes

Terminating IRLM: Use the STOP irlmproc (z/OS IRLM) command to terminate IRLM.

Deregistering IRLM: You can use the NODUMP option to deregister IRLM before stopping it. This action prevents the automatic restart manager from immediately trying to restart IRLM.

Example

Enter the following command on the system console:

F KRLM001,ABEND

Response on the z/OS system console is as follows:

 DXR124E IR21001 ABENDED VIA MODIFY COMMAND
*IEA911E COMPLETE DUMP ON SYS1.DUMP00
  FOR ASID(0004)
   ERROR ID = SEQ00001 CPU00 ASID0004 TIME08.34.59.9
 DXR121I IR21001 END-OF-TASK CLEANUP SUCCESSFUL
 IEF450I IR21001 IR21001 - ABEND=S000 U2020 REASON=00000000

The default is dump. If you do not want a dump, you must specify the following command:

F KRLM001,ABEND,NODUMP
