MQ Connections

Note: MQ Connection resources and MQ transports require the version 6 WebSphere MQ client library, which is not bundled with the ALSB installer. You can obtain the WebSphere MQ 6.0 client library from the IBM Web site at http://www-306.ibm.com/software/integration/wmq/library/.
Note: To use MQ Connection resources and the native MQ transport in ALSB, you must add the MQ client library to the classpath. One option is to copy it to your DOMAIN_NAME/lib directory, where DOMAIN_NAME is the name of the directory in which you located the domain, typically BEA_HOME\user_projects\domains\DOMAIN_NAME.

MQ connections are sharable resources that can be reused across multiple MQ proxy and business services. MQ proxy and business services must connect to a MQ queue manager before accessing an MQ queue. MQ Connection resources provide the connection parameters required for connecting to a MQ queue manager.

Each MQ Connection resource has a connection pool. Every business or proxy service using a given MQ Connection resource to get a connection to a given queue manager uses the same connection pool that was created for that resource. Thus, multiple business services and proxy services using the same queue manager share a connection pool.

To learn more about ALSB MQ Connection resources and native MQ transports, see the Native MQ Transport User Guide.
