Abnormal endings

ICSF has an abnormal ending in these cases only:
  • When an error occurs during ICSF initialization
  • When you specify FAIL(ICSF) in the callable service exit installation option
  • When the setting of a cryptographic domain index fails

If an abnormal end occurs in any other cases, your application or unit of work ends; however, ICSF is still available.

ICSF has an abnormal end code unique to ICSF. Errors specific to ICSF result in an abnormal end code of X'18F' and a unique reason code. In general, all abnormal ends occurring within ICSF result in an appropriate system dump, user dump, or LOGREC recording.

Review the reason code to see if the abnormal end was an installation or user error. For a list of the reason codes for abnormal end code X'18F', refer to z/OS MVS System Codes. If you cannot resolve the problem, save the dump and contact the IBM Support Center.
