The WebSphere® MQ link connects the messaging engine as a queue manager to WebSphere MQ, providing a bridge between the bus and a WebSphere MQ network.

If WebSphere MQ functionality has been disabled at any scope, an informational message indicating that WebSphere MQ has been disabled is displayed. In a single server environment this informational message is only displayed when the server is restarted after WebSphere MQ functionality has been disabled. In a network deployment environment the informational message is displayed immediately. For more information see Disabling WebSphere MQ functionality in WebSphere Application Server.
The Configuration tab shows configuration properties for this object. These property values are preserved even if the runtime environment is stopped then restarted. See the information center task descriptions for information about how to apply configuration changes to the runtime environment.

The virtual queue manager name by which the local bus is to be known to a WebSphere MQ network. It is generally recommended that you set the virtual queue manager name to match the name of the local bus. As WebSphere MQ queue manager names can be no longer than 48 characters, you must ensure that the length of the local bus name does not exceed 48 characters.

The maximum number of messages that can be sent through a channel before taking a checkpoint.
For information about choosing the batch size, see the description of the Batch size (BATCHSZ) property in the Intercommunication section of the WebSphere MQ information center.
Dynamic updates to this property are effective when the channel restarts. Use the Runtime tab to check the current state.

Data type | Integer |
Range | 1 through 9999 |
The maximum message length, in bytes, that can be transmitted on any channel for the WebSphere MQ link. This is compared with the value for the corresponding partner WebSphere MQ channel and the actual maximum used is the lower of the two values.
For more information about choosing a value for the maximum message size, see the description of the Maximum message length (MAXMSGL) property in the Intercommunication section of the WebSphere MQ information center.
Dynamic updates to this property are effective when the channel restarts. Use the Runtime tab to check the current state.

The negotiated time, in seconds, between heartbeat flows passed from the WebSphere MQ link sender channel to the WebSphere MQ receiver channel when there are no messages on the transmission point being served by the WebSphere MQ link sender channel.
Heartbeats give the receiving channel the opportunity to quiesce the channel connection.

Whether or not a running instance of a WebSphere MQ link receiver channel (associated with this MQ link) should be adopted or not. In the event of a communications failure, it is possible for a running instance of a WebSphere MQ link receiver channel to be left waiting for messages. When communication is re-established, and the partner WebSphere MQ sender channel next attempts to establish a session with the WebSphere MQ link receiver channel, the request will fail as there is already a running instance of the WebSphere MQ link receiver channel that believes it is in session with the partner WebSphere MQ sender channel. You can overcome this problem by selecting this option, which causes the already running instance of the WebSphere MQ link receiver channel to be stopped and a new instance to be started.
Dynamic updates to this property are effective when the channel restarts. Use the Runtime tab to check the current state.

The Runtime tab shows runtime properties for this object. These properties directly affect the current runtime environment, but are not preserved when that environment is stopped. To preserve runtime property values, change the equivalent property values on the Configuration tab. See the information center task descriptions for information about how to apply configuration changes to the runtime environment.
