A WebSphere MQ client link presents the messaging engine, and therefore the bus, as a WebSphere MQ queue manager to which WebSphere MQ clients can attach. This behavior enables WebSphere Application Server Version 5 JMS clients to use messaging resources on the bus.

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 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.

The name of the channel for the WebSphere MQ client link, used to flow messages between WebSphere MQ clients and the bus.
The name of the WebSphere MQ server connection channel that this client link will use to represent itself to clients. It must exactly match the value specified by the client for a connection to be established. For Version 5 embedded messaging clients a value of "WAS.JMS.SVRCONN" must be specified. You should not define two MQ client links that share both channel name and queue manager name. However , it is possible to have client links with identical channel names if they specify different queue manager names.
.Required | Yes |
Data type | String |
The name of the WebSphere MQ queue manager on which the WebSphere MQ sender channel, that is connected to this MQ link receiver channel connection instance, is running.
The WebSphere MQ client link for use by JMS applications on WebSphere Application Server Version 5.1 has the queue manager name WAS_nodeName_jmsserver. You should not use this name on any other WebSphere MQ client link that is assigned to a messaging engine on the same node.
Required | Yes |
Data type | String |
Whether or not this is the default queue manager for the WebSphere MQ clients.
If a client does not specify the name of the queue manager it is to connect to, it will be connected to an MQ client link with a matching channel name that has been marked as being the default, if one matching this criterion can be found.
Required | No |
Data type | Boolean |
The maximum message length, in bytes, that can be transmitted using the WebSphere MQ client link.
Required | No |

The time, in seconds, to wait before checking that a client requesting an operation is still active.
If the sending channel has had a communication from the receiving channel within the batch heartbeat interval, the receiving channel is assumed to be still active, otherwise a "heartbeat" signal is sent to the receiving channel to check.
Required | No |
Data type | Integer |
Range | 0 through 999999 A value of 0 (zero) indicates that the heartbeat mechanism is not used. |
Whether the WebSphere MQ client link is started or stopped when the associated messaging engine is first started. Until started, the WebSphere MQ client link is unavailable.
