Question & Answer
Why did I get message CA Top Secret message TSS9406E followed by CICS message DFHUS0002 and a dump for error US0002?
These are the messages:
TSS9406E PROBABLE SITE INTERFACING ERROR (036)
DFHUS0002 A severe error (code X'0309') has occurred in module DFHUSAD.
CA Top Secret Fix # RO90784 will correct this error.
You can follow these steps to determine if you have the same problem that is :
Look at a dump was taken for the CICS US0002 error.
Find the exception trace entries (EXC) in the trace for the error.
Look to see if the problem happened during DELETE_EXPIRED_USERS ( Delete Expired Users) processing under the TI (Timer) task. You can verify this by going to the KE domain in the dump and finding the KE_NUM for the task. Find the @STACK entry for the DFHUSAD process for the task. See if DELETE_EXPIRED_USERS is the process that gets the SEVERE_ERROR.
If you would like to see what userid was involved in the error, go to the storage pointed to by the @STACK address. At about offset +x'6C0' will be the userid that CICS requested be deleted and was rejected by the external security manager (ESM).
