Shutting down an IMS network (SLU P)

Shutting down an IMS network may or may not include IMS.

The IMS /CHECKPOINT command is used to invoke termination of the network and a shutdown of IMS. The format of /CHECKPOINT used determines whether the network termination occurs immediately or waits for workstation processing to complete:
/CHECKPOINT FREEZE|DUMPQ|PURGE QUIESCE
Allows all workstations to complete normal processing before shutting down IMS.
/CHECKPOINT FREEZE|DUMPQ|PURGE
Causes immediate session termination for all workstations.
