Published information is sent in an IBM MQ message, and the subject of the information is identified by its topic. The publisher specifies the topic when it publishes the information, and the subscriber specifies the topics about which it wants to receive publications.
What is a message topic?
A sibling to a message queue, a message topic provides a lightweight mechanism to broadcast asynchronous event notifications, and endpoints that allow software components to connect to the topic in order to send and receive those messages.
How do I create a topic in IBM MQ?
- Expand the queue manager that hosts the Publish/Subscribe Engine to display the object-folders in the Navigator view.
- Right-click Topics, then click New > Topic.
