Stopping a channel initiator

We can stop a channel initiator using MQSC commands or using the operations and control panels.

To stop a channel initiator using the MQSC commands, use STOP CHINIT.

Use the operations and control panels, starting from the initial panel, complete these fields and press enter:

Field	Value
Action	7 (Stop)
Object type	SYSTEM
Name	Blank

The Stop a System Function panel is displayed. The text following the panel explains how you to use this panel:

Select function type 1 (channel initiator) and press enter.

The channel initiator waits for all running channels to stop in quiesce mode before it stops.

Note: If some of the channels are receiver or requester channels that are running but not active, a stop request issued to either the receiver or sender channel initiator causes it to stop immediately.

However, if messages are flowing, the channel initiator waits for the current batch of messages to complete before it stops.
