Configuring your brokers to conform to your license
Changing the function levels of your brokers
When a fix pack is delivered, it might include new nodes that you can add to your message flows to provide specific functions.
For Version 8.0.0.0, the function level of new brokers is set to a default value that is equivalent to the value 8.0.0.0. At this level, nodes that might be added by later fix packs are not supported by the broker.
Nodes that are added in later fix packs are available in the WebSphere Message Broker Toolkit, and you can include these nodes in a message flow. You can deploy the message flow to a broker only if you have set the function level of that broker to the value that represents the fix pack in which the nodes are first delivered.
Because you can control the function level of each broker, you can try out new nodes on test brokers without affecting the operation of your production brokers. When you are satisfied that the nodes provide the function that you require, and work as you expect, you can set the function level of other brokers in your domain, when appropriate.
To change the function level of a broker, use the mqsichangebroker command, specifying the -f flag with the appropriate value.
