ICSF writes messages to the job log, and to the security console and the operator console.
ICSF writes most of its messages to the job log. Messages that demand action from the master console operator will display on the operator console, and messages related to system security will display on the security console. Some of these console messages will appear only on the console, and some will also be written to the job log. Messages that are not displayed on either the operator or security console are written to the job log.
For a description of each ICSF message, see z/OS Cryptographic Services ICSF Messages.
