When you are running remote transactions over ISC and IRC links USRDELAY defines the time for which entries can remain signed onto the remote CICS region. For information on specifying USRDELAY, see the CICS® System Definition Guide. See the CICS Performance Guide for information on tuning.
If you alter the RACF profile of a signed-on remote user (for example, by revoking the user), CICS continues to use the authorization established at the first attach request until the entry is removed from the sign-on list.
