Orderly shutdown

An orderly shutdown of the connection lets each CICS transaction terminate before thread subtasks are detached. When you use this method, there should be no in-doubt units of work when you reconnect CICS. An orderly termination occurs in each of the following situations:

• The CICS terminal operator issues a CKQC STOP command. CICS and the queue manager remain active. The command can be issued from the command line, from a terminal using the CKQC panels, or from a program, see topic Stopping a connection from a CICS application program.

• The CICS terminal operator issues the CICS command:

  CEMT PERFORM SHUTDOWN

  For information about the CEMT PERFORM SHUTDOWN command, see the CICS-Supplied Transactions manual.

• The queue manager is quiesced by the command:

  +CSQ1 STOP QMGR MODE(QUIESCE)

  This stops the queue manager, allows the currently identified tasks to continue normal processing, and does not allow new tasks to identify themselves to the queue manager. CICS remains active.
