Shutting down an IMS network

You can shut down the IMS network while shutting down IMS or without shutting down IMS. Use the /CHECKPOINT command to terminate the network and shut down IMS. Use the /STOP DC command to terminate the network only.

You can also use the VTAM® HALT NET command to shut down the VTAM network.

If your network includes APPC, be aware of the following conditions:

Allocated LU 6.2 conversations might prolong the shutdown process.
Network shutdown does not prevent the application programs from establishing LU 6.2 conversations.
LU 6.2-originated transactions, not scheduled but on the IMS queue, terminate with message DFS1970.
