There is no equivalent of a CICS® immediate shutdown in DBCTL. If you need to force termination of DBCTL, the MVS™ console operator has to issue an MVS MODIFY jobname STOP command. This causes an abnormal termination without a dump. If you want a dump to be taken, use an MVS MODIFY jobname DUMP command. For guidance on using MVS commands with IMS™, see the IMS Operator’s Reference manual.
