Stopping the sender channel on a WebSphere MQ link

You can stop the sender channel on a WebSphere® MQ link while leaving the link itself running.

Before you begin

You might want to tell the WebSphere MQ network administrator that you are about to stop a channel.

About this task

When you stop the sender channel on a WebSphere MQ link, communication with the target WebSphere MQ network on that channel is stopped for both point-to-point messaging and publishing and subscribing. Messages are held at their transmission locations.

Procedure

  1. Start the administrative console.
  2. In the navigation pane, click Service integration > Buses > bus_name > [Topology] Messaging engines > engine_name > [Additional properties] WebSphere MQ links > link_name > [Additional Properties] Sender channel .
  3. Select the check box next to the channel you want to stop.
  4. In the Stop mode list, select Quiesce or Force.
  5. In the Target state list, select Inactive or Stopped.
  6. Click Stop.

Results

Only the sender channel is affected by this procedure. The resultant state of the sender channel depends on the options you chose:
Table 1. Stop modes
