APAR status

• Closed as program error.

Error description

• An ABEND0C4 can occur in module DFSST500, after installation
  of APAR PM52121 / PTF UK78835, because the GETSTOR request
  fails. This request fails because the GETSTOR call was coded
  incorrectly.
  In addition to this problem, a small number of PM52121 related
  issues are being included in this service.

  1.The original problem reported is an ABEND0C4 in DFSST500
    attempting to use storage from an IMODULE GETSTOR that failed.
    It was also found that the FREESTOR for the same storage was
    attempted when no storage was acquired. These conditions are
    only encountered on RSR Tracking Systems.
  
  2.DFSRCP10 was using SP231 - CSA for large type47 records. SP0
    private storage is more appropriate.
  
  3.DFSRBLB0 attempts to free storage that was never acquired.
  
  4.ABEND0C4 in DFSRBOI0 running Dynamic Backout in a Batch IMS
    AUTHORIZED. The IMS GETSTOR request was using SP231, Key7
    and was allowed for the KEY8 caller due to authorization.
    When the Key7 storage was then being cleared, ABEND0C4
    occurred due to the caller running KEY8.
  
  5.R7 may lose addressability to the PSTLOGWA in DFSRBOI0.
  

Problem conclusion

• GEN:
  KEYWORDS:
   RSRImpact
  
  *** END IMS KEYWORDS ***
  1.DFSST500 now correctly acquires storage and only attempts to
    free it when it has been successfully acquired.
  
  2.DFSRCP10 now acquires and deletes storage in SP0 instead of
    SP231.
  
  3.DFSRBLB0 now checks for the presence of storage before
    attempting to free it.
  
  4.DFSRBOI0 now determines if the caller is authorised and makes
    the decision to handle GETSTOR requests in the key of the
    caller. SP231 is used for authorized callers while SP0 is now
    used for callers running non-authorized.
  
  5.R7 is reset to point to the PSTLOGWA to correct possible loss
    addressability under label RBOI510.
