Administering an existing IBM MQ link
The IBM MQ enables the exchange of point-to-point and publish/subscribe messages with a IBM MQ network. After you have created a WebSphere® MQ link you can undertake various administrative actions on the link.
About this task
The IBM MQ link connects a WebSphere Application Server and a IBM MQ network. Because these two systems are working together, their functions must be in step so that each is aware of the status of the other. Administrative actions on the IBM MQ link and its functions include the following:
Procedure
- Modify individual functions of the IBM MQ link.
You can modify the link itself, add or modify the sender channel and receiver channel, or define a broker profile and associated topic mappings.
- Modify security for a IBM MQ link.
- View the status of a IBM MQ link and its components. You can view the status of a IBM MQ link and its sender and receiver channels, and you can view the status of subscriptions for a IBM MQ link publish/subscribe broker profile.
- Start a IBM MQ link.
- Stop a IBM MQ link.
When you stop the link, all its functions are stopped too. For example, stopping a IBM MQ link with broker profiles on it might leave a message broker in the IBM MQ network with a backlog of messages. For more information, see Stopping a WebSphere MQ link, Stopping the sender channel on a WebSphere MQ link and Stopping the receiver channel on a WebSphere MQ link.
- Delete a IBM MQ link or one of its components. When you remove a foreign bus connection between a service integration bus and a IBM MQ network, you also delete the associated IBM MQ link along with any publish/subscribe broker profiles and topic mappings. You can also delete a IBM MQ link publish/subscribe broker profile or delete a topic mapping from a IBM MQ link.

You might want to view the status of a IBM MQ link or its components because you intend to stop the IBM MQ link and you want to see if there are any messages currently held on it, or you are about to delete the IBM MQ link and you have to verify there are no messages on it, or messages have not arrived at their expected destination and you want to check if they are being held, pending transmission over the IBM MQ link.Viewing the status of subscriptions for an IBM MQ link publish/subscribe broker profile
You can use the administrative console to view the status of subscriptions for a broker profile on a IBM MQ link.States of the WebSphere MQ link and its channels
For each possible state of a WebSphere MQ link, this table lists the associated states of the link's sender and receiver channels.Starting a IBM MQ link
Change the state of a IBM MQ link from stopped to started.Stopping a WebSphere MQ link
You can change the state of a WebSphere MQ link from "Started" or "Running" to "Stopped". When you stop a WebSphere MQ link, all communication with the target IBM MQ network is stopped for both point-to-point and publication and subscription. Messages waiting for transmission are held on the service integration bus, and the MQ sender channel cannot start. If there is a publish/subscribe bridge on the WebSphere MQ link, its operations are stopped.Deleting a IBM MQ link publish/subscribe broker profile
This describes how you delete a broker profile and all topic mappings on a IBM MQ link, which forms a publish/subscribe bridge between WebSphere Application Server and a IBM MQ network.Deleting a topic mapping on an IBM MQ link publish/subscribe broker profile
This describes how you delete a topic mapping on a broker profile on a IBM MQ link, which forms part of a publish/subscribe bridge between WebSphere Application Server and IBM MQ.
