Start and stop WebSphere MQ client links
Use this task to start or stop WebSphere MQ client links, to stop message flows between the default messaging provider and JMS applications developed for WAS v5.1, connected through the client links.
We can start a WebSphere MQ client link that is not running (has a runtime status of Stopped) or stop a client link that is running (has a runtime status of Started). This also starts or stops all client connections on the selected WebSphere MQ client links. Alternatively, you can start or stop individual client connections on the WebSphere MQ client link, as described in Start and stop WebSphere MQ client connections.
When stopping a client link, you can choose whether to force the client link to stop immediately or after any messages currently on its client connections have been processed. We can also choose the final state that you want the client link to be in when it has been stopped.
To start or stop one or more WebSphere MQ client links, use the admin console to complete the following steps.
Procedure
- Display the WebSphere MQ client links collection page. Click Service integration -> Buses -> bus_name -> [Topology] Messaging engines -> engine_name -> [Additional Properties] WebSphere MQ client links .
- Select the check box next to the name of each client link to start or stop.
- Click the appropriate button:
Start Start selected items. This enables JMS applications to use the client link to access JMS resources provided by the default messaging provider. Stop Stop a selected WebSphere MQ client link. We must first have selected the link to be stopped. We can choose the mode of stop action and the required state when the link has been stopped:
- Stop mode:
- Force
- Stop the link immediately.
- Quiesce
- Stop the link after any messages currently on its client connections have been processed.
- Target state:
- Inactive
- Stop the link to an inactive state. If an application tries to use the link, the link is started again.
- Stopped
- Stop the link to a stopped state. Applications cannot use the client link. The link can only be started again by administrator action.
Results
The status of the client link changes and a message stating that the link has started or stopped is displayed at the top the page.
