You can use WebSphere® Application Server custom properties to configure connections to a multi-instance queue manager and to configure the automatic client reconnect feature introduced in WebSphere MQ Version 7.0.1.
You can use multi-instance queue managers to configure multiple instances of the same queue manager on two or more computers. The multi-instance queue manager facility enables you to configure highly available messaging systems based on WebSphere MQ without requiring a hardware cluster technology such as High Availability Cluster Multi-Processing (HACMP).
When multiple instances of a multi-instance queue manager are started, one instance of the queue manager becomes the active instance, and the remaining instances of the queue manager become standby instances. If the active instance fails, a standby instance running on a different computer automatically takes over.
The WebSphere MQ messaging provider in WebSphere Application Server Version 7.0 Fix Pack 13
and later can connect to a multi-instance queue manager. To make use
of this facility, you must specify WebSphere MQ messaging provider connection
factory or activation specification custom properties.
