Controlling the functional level of WebSphere Message Broker
You can control the functional level of your broker to enable new functionality added in WebSphere® Message Broker fix packs.
The default functional level of the broker represents the level for WebSphere Message Broker Version 8.0.0.0. At this level, some functionality added by later fix packs is not supported by the broker.
Nodes and parsers that are added in later fix packs are available in the WebSphere Message Broker Toolkit, and you can include these nodes and parsers in a message flow. You can deploy the message flow to a broker only if you have set the functional level of that broker to the value that represents the fix pack in which the nodes and parsers were first delivered.
You can control the functional level of each broker, therefore 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 functions that you require, and work as you expect, you can set the functional level of other brokers in your domain when appropriate.
To change the function level of a broker, use the mqsichangebroker command and set the -f parameter to the appropriate value. For more information about the use of the mqsichangebroker command, see mqsichangebroker command.
You can check the functional level of a broker by using the mqsireportbroker command (see mqsireportbroker command) or through the WebSphere Message Broker Explorer.
If you enable a certain functional level, you also enable all the functions added at lower levels. For example, if you enable new fix pack 3 functions, you automatically enable new functions for fix packs 1 and 2.
You can enable all new functionality by setting the function level to all.
The list of functions that are enabled for each function level is described in the following sections.
Version 8.0.0.1
You can install Version 8.0.0.1 as a full, generally available version, or as a fix pack. Version 8.0.0.1 has the functions enabled for V8.0.0.1 regardless of the installation route chosen.
