PK84958: RSR TRACKING IMS GOT ABEND0C1 DUE TO WILD BRANCH FROM DFSLRIQS.

APAR status

• Closed as program error.

Error description

• DFSLRIQS got ABEND0C1 because it was posted from DBFDT400
  repeatedly without AWE.
  DBFDT400 is looping in DFSLRTHR macro due to TQE (Throttle Queue
  Element) is pointing to itself.
  Originally, ECB was suspended in ThrottleSelf routine in
  DFSLRRDU. DISP trace was filled with this repeated IPOST from
  DBFDT400.

    DFSLRIQS got ABEND0C1 because it was posted from DBFDT400
  repeatedly without AWE.
    DBFDT400 is looping in DFSLRTHR macro due to TQE (Throttle
  Queue Element) is pointing to itself.
    Originally, ECB was suspended in ThrottleSelf routine in
  DFSLRRDU. DISP trace was filled with this repeated IPOST from
  DBFDT400.
    This is the result of the ThrottleSelf routine getting called
  again after the ThrottleSelf TQE has been created.  A new TQE
  will be created that has a tqe_next pointer pointing to itself.
  

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
    DFSLROPR, DFSLRRDU, DFSLRRR0 and DFSRWRR0 all have
  ThrottleSelf routines and have been changed to recognize
  when there already exists a ThrottleSelf TQE and bypass
  creating another.
  

Temporary fix
