Refreshing the OAM after changing a user's authorization

In WebSphere MQ, you can update the OAM's authorization group information immediately after changing a user's authorization group membership, reflecting changes made at the operating system level, without needing to stop and restart the queue manager.

Note:
When you change authorizations with the setmqaut command, the OAM implements such changes immediately.

Queue managers store authorization data on a local queue called SYSTEM.AUTH.DATA.QUEUE. This data is managed by amqzfuma.exe.
