User ID reverification

If the RACF definition of a user who is using WebSphere MQ resources has been changed--for example, by connecting the user to a new group--we can tell the queue manager to sign this user on again the next time it tries to access a WebSphere MQ resource. We can do this by using the WebSphere MQ command RVERIFY SECURITY. For example:

Note:
If you turn off user ID timeout for long periods of time (days or even weeks), while the queue manager is running, remember to perform an RVERIFY SECURITY for any users that have been revoked or deleted in that time.
