Before using the User Manager, keep the following things in mind:
The imqusermgr command must be run on the host where the broker is installed.
If a broker-specific user repository does not yet exist, you must start up the corresponding broker instance to create it.
You must have appropriate permissions to write to the repository; in particular, on Solaris and Linux platforms, you must be logged in as the root user or the user who first created the broker instance.
