No publish-subscribe message distribution
The publish-subscribe method of distributing messages is not currently supported by the MQ binding though WMQ itself supports publish-subscribe. However, the MQ JMS binding does support this method of distribution.
Shared receive queues
Multiple WebSphere® MQ export and import bindings
expect that any messages present on their configured receive queue
are intended for that export or import. Import and export bindings
should be configured with the following considerations:
- Each MQ import must have a different receive queue because the MQ import binding assumes all messages on the receive queue are responses to requests that it sent. If the receive queue is shared by more than one import, responses could be received by the wrong import and will fail to be correlated with the original request message.
- Each MQ export should have a different receive queue, because otherwise you cannot predict which export will get any particular request message.
- MQ imports and exports can point to the same send queue.
