IMS 15.4 for z/OS

If possible, notify all users that IMS is to be terminated and when it will occur. This allows users to complete their work, or at least reach a convenient stopping point. Issue /BROADCAST ACTIVE as much in advance of termination as possible. If you have users on the system and you wish to notify that IMS is coming down use:

##,/BRO ACTIVE 'TERMINATING'. (the period is required)

**NOTE If your entering the commands from the SDSF log you will need to put a "/" in front of the commands. ## should be the number associated to the IMS outstanding reply.

There are several ways to stop IMS:

To terminate the control region without dumping the message queues.

##,/CHE SNAPQ

##,/CHE FREEZE

DFS994I IMS SHUTDOWN COMPLETED

To terminate the control region and dump the message queues , use either ONE of these commands.

##,/CHE DUMPQ or ##,/CHE PURGE

Please review all the above commands in the IMS Sample Operating Procedures

Once you have stopped IMS you need to stop IRLM:

P IMS15RL1

You should see the following messages:

DXR110I IRLM001 STOP COMMAND ACCEPTED
$HASP395 IMS15RL1 ENDED

The proc should match which ever version of IMS your stopping.
