Distributed queuing and queue-sharing groups
To complement the high availability of messages on shared queues, the distributed queuing component of WebSphere MQ has additional functions to provide the following:
- Higher availability to the network.
- Increased capacity for inbound network connections to the queue-sharing group.
Figure 6 illustrates distributed queuing and queue-sharing groups. It shows two queue managers within a sysplex, both of which belong to the same queue-sharing group. They can both access shared queue SQ1. Queue managers in the network (on AIX and Windows for example) can put messages onto this queue through the channel initiator of either queue manager. Cloned applications on both queue managers service the queue.
