PI56633: ABENDS0C4 OCCURRED WITHOUT ISSUING CHANGE DB COMMANDS AFTER ABENDS806

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• MAINTAIN with ONLINE(Y) has been changed to issue CHANGE DB
  NOREORGI commands after any ABEND by the PTF UI32794.
  In the client's scenario; an ABENDS806 occurred and the CHANGE
  DB NOREORGI command was issued successfully. The client then
  experienced an ABENDS0C4 after the  ABENDS806 and the CHANGE DB
  NOREORGI command was not issued. So the complexity of this issue
  is to fix the 0C4 and ensure the CHANGE DB NOREORGI command will
  be issued in all conditions.

  * PROBLEM DESCRIPTION: MAINTAIN with ONLINE(Y) can cause       *
  *                      ABENDS0C4 without issuing CHANGE DB     *
  *                      NOREORGI commands after any ABEND.      *

  * RECOMMENDATION:                                              *
  ****************************************************************
  When each subtask of MAINTAIN is started, some data with the
  TCB address (hereafter referred to as Named object) is saved
  in a common pool. The Named object is retrieved from several
  programs by using TCB address of each subtask, and is deleted
  in the shutdown process of the subtask.
  However, if a subtask terminates with any ABEND before the
  shutdown process, the Named object for the subtask is remained
  as a garbage.
  After the ABEND, a new subtask is started to issue CHANGE DB
  commands. At this point, if the identical TCB address is
  assigned for the new subtask by coincidence, the ABENDS0C4
  can occur by retrieving the garbage.
  

Problem conclusion

• IHCXNAOB and IHCYSCHD have been changed to delete the garbage
  after any ABEND.
