IBM MQ messaging provider modes
The IBM® MQ messaging provider has three modes of operation: normal mode, normal mode with restrictions, and migration mode.
- IBM MQ messaging provider normal mode
- IBM MQ messaging provider normal mode with restrictions
- IBM MQ messaging provider migration mode
The IBM MQ messaging provider normal mode with restrictions uses the JMS 2.0 API, but not the new IBM MQ 8.0 features such as shared subscriptions, delayed delivery, or asynchronous send.
- IBM WebSphere MQ 7.0 or later, queue manager in bindings or client mode, but this mode uses only those features that were available to a IBM WebSphere MQ 6.0 queue manager.
- IBM WebSphere MQ 6.0 or earlier queue manager in client mode.
If you want to connect to IBM Integration Bus by using IBM MQ Enterprise Transport, use the IBM MQ messaging provider migration mode. If you use IBM MQ Real-Time Transport, the IBM MQ messaging provider migration mode is automatically selected because you have explicitly selected properties in the connection factory object. Connection to IBM Integration Bus using the IBM MQ Enterprise Transport follows the general rules for mode selection that is described in Rules for selecting the IBM MQ messaging provider mode.
