Before you start:
On UNIX systems
and Linux, you must set up your command-line environment before creating a
broker, by running the product profile; refer to Environment variables after installation.
Modify a broker using the command line on the system where the broker component is installed.
The parameters you can change on the broker affect the physical broker, created using the command line.
You can also modify the broker reference in the workbench, where it is possible to change broker properties, such as multicast properties.
Follow the link for the appropriate platform.
