Refreshing the OAM after changing a user's authorization
In IBM MQ, we can refresh 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. In order to do this, issue the REFRESH SECURITY command.
Note: When we 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. Parent topic: Configure services and componentsRelated information
