Stopping a WebSphere MQ link

This topic describes how you change the state of a WebSphere® MQ link from started or running to stopped.

Before you begin

You may wish to inform the administrator of the WebSphere MQ network that you are about to stop this WebSphere MQ link.

If you stop the WebSphere MQ link all communication with the target WebSphere MQ network will cease for both point-to-point and publication and subscription. Messages will be held at their transmission locations.

About this task

You can also stop either the sender or receiver channel on the WebSphere MQ link, while leaving the link itself running. See Stopping the sender channel on a WebSphere MQ link, and Stopping the receiver channel on a WebSphere MQ link.

To stop a WebSphere MQ link, use the administrative console to complete the following steps:

Procedure

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

Results

The resultant state of the WebSphere MQ link, its sender and receiver channels, and the WebSphere MQ sender channel which is connected to the WebSphere MQ link receiver channel, depends on the options you chose:

These are the final states that the sender, receiver and WebSphere MQ link will transition to. If you specify a mode of QUIESCE for either of the two final states, the channels and link may not transition into their final states immediately. Instead they temporarily transition through other states required to reach their final state.

For more details about stopped states of the WebSphere MQ link, see States of the WebSphere MQ link and its channels.

What to do next

Now you have stopped the WebSphere MQ link:
