Environment

Release : 16.0

Component : CA ACF2 for z/OS

Resolution

When stopping and starting ACF2, any resource or dataset validation or system access request will receive an ACF2 ACF9BCCC or ACF9CCCC message prompting(console prompt) for a response of 'U' to continue, 'C' to cancel or 'W' to wait while ACF2 is down.

If the operator replies with a U, the job continues without CA ACF2 access controls. Replying with a C flushes the job without further intervention. If the operator replies with a W, CA ACF2 security routines wait for CA ACF2 to become ready to process requests.

To reduce the number of ACF9BCCC and ACF9CCCC prompts the system should quiesced and steps to pause or reduce online region activities should be taken before stopping ACF2.
