Using automatic client reconnection in Java SE and Java EE environments

You can make use of IBM® MQ automatic client reconnection to facilitate various high availability (HA) and disaster recovery (DR) solutions within a Java SE and Java EE environment.

Multi-instance queue managers are instances of the same queue manager configured on different servers. One instance of the queue manager is defined as the active instance and another instance is defined as the standby instance. If the active instance fails, the multi-instance queue manager restarts automatically on the standby server.

Both the active and standby queue managers have the same queue manager identifier (QMID).IBM MQ client applications that connect to a multi-instance queue manager can be configured to automatically reconnect to a standby instance of a queue manager by using automatic client reconnection.
