Wild cards in topic mapping

Wild cards can be used in topic mapping on a WebSphere® MQ 鏈結 for publish/subscribe messaging, but there are differences between wild cards in WebSphere Application Server service integration, and wild cards in a IBM MQ network.

Publish/subscribe messaging in the IBM MQ network uses wild cards # and +. These wild cards are represented as /. and * respectively in the service integration bus. However, the publish/subscribe bridge on the IBM MQ link supports only the /. wild card, and only at the end of the topic. For example, stock//. in the service integration bus is equivalent to stock/# in the IBM MQ network, meaning all messages with "stock" at the beginning of the topic.

When you use wild cards in the topic mappings that you enter on the IBM MQ link administrative console panels, you must use the publish/subscribe bridge symbols, not the equivalent IBM MQ network symbols. The publish/subscribe bridge handles conversion automatically.
