Before you start
You must have a compiled user-defined extension, which has been supplied either by a third party vendor, or by a WebSphere® Message Broker Version 6.0 user.
For C user-defined extensions, it is recommended that the .pdb file, which corresponds to the .lil file, is also stored in the chosen directory. The .pdb file provides symbolic information that is used by WebSphere Event Broker when displaying stack diagnostic information in the event of access violations or other software malfunctions.
These two situations assume that you have already completed the previous step, and have therefore used either the mqsichangebroker command or the mqsicreatebroker command to notify the broker of the directory in which the user-defined extension files have been placed.
When you have installed a user-defined node, it is referred to by its schema and name, just like a message flow.
