TMA-CICS-1.1.1
Ensure that RACF changes are accepted immediately
Description
RACF sends a type 71 ENF signal to listening CICS regions when a RACF CONNECT or REMOVE command changes a user's resource authorization level. It also sends a type 71 ENF signal when a user ID is revoked. This can occur when a RACF REVOKE command is issued or when a user ID is revoked automatically as a result of too many failed password attempts.
How it is checked
