PH52365: REDUCE OVERHEAD FROM REVOKED USERIDS

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• A customer has remote devices that execute a programmatic script
  to issue a logon attempt via IMS Connect. Many times these IDs
  have been revoked or are obsolete. When the script receives a
  RACF failure, the signon attempt will be continually retried (at
  machine speeds) infinitely until someone is alerted and
  undertakes some manual efforts to kill the device's logon
  attempts.

  attempts.
  

Problem conclusion

• A new CEXCTLIN option on the SECURITY command is added to
  control the caching of verify failures. After the first failing
  request the overhead of the SAF verify for subsequent requests
  is avoided.
