Stop a channel

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

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

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

Field	Value
Action	7 (Stop)
Object type	channel type (for example SENDER) or CHANNEL
Name	CHANNEL.TO.USE
Disposition	The disposition of the object.

The Stop a Channel panel is displayed. The text following the panel explains how to use the panel:

Select the disposition of the channel for which the stop is to be done and on which queue manager it is to be stopped.

Choose the stop mode that you require:

Quiesce

The channel stops when the current message is completed and the batch is then ended, even if the batch size value has not been reached and there are messages already waiting on the transmission queue. No new batches are started. This mode is the default.

Force

The channel stops immediately. If a batch of messages is in progress, an 'in-doubt' situation can result.

Choose the queue manager and connection name for the channel you want to stop.

Choose the status that you require:

Stopped

The channel is not restarted automatically, and must be restarted manually. This mode is the default if no queue manager or connection name is specified. If a name is specified, it is not allowed.

Inactive

The channel is restarted automatically when required. This mode is the default if a queue manager or connection name is specified.

Press enter to stop the channel.

See Stop and quiescing channels for more information. For information about restarting stopped channels, see Restarting stopped channels.

Note: If a shared channel is in a retry state and the channel initiator on which it was started is not running, a STOP request for the channel is issued on the queue manager where the command was entered.
