How and when to modify the properties of a WebSphere® MQ link.
Decide which method to use to configure these resources. You can modify a WebSphere MQ link by using the administrative console as described in this task, or you can modify a WebSphere MQ link by using the wsadmin tool.
You have to know the name of the bus, and the messaging engine on the bus that contains the WebSphere MQ link you want to modify.
A WebSphere MQ link provides a server to server channel connection between a service integration bus and a WebSphere MQ queue manager or queue-sharing group, which acts as the gateway to the WebSphere MQ network. At any time after you create a new WebSphere MQ link, you can modify its properties.
When you use the foreign bus connection wizard to connect a bus and a WebSphere MQ queue manager or queue-sharing group (known as the "gateway queue manager") to use point-to-point messaging or publish-subscribe messaging, one or more WebSphere MQ links are created and configured as part of the task. However the wizard does not ask you to set all possible properties of a WebSphere MQ link, and some of the link properties are not set or are set to default values. You can fine tune these properties by modifying the link.
When you create a new WebSphere MQ link, you can also choose not to create sender or receiver channels. These channels can be added later by modifying the link.
When you use the foreign bus connection wizard to create a WebSphere MQ link for point-to-point messaging, you can later modify the link for publish-subscribe messaging by adding a publish/subscribe broker profile to the link.
