Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• HD Pointer issues MSGFABP1520W when it detects unknown data
  (T2) errors or Pointer errors. But, the message does not tell
  whether the detected errors are T2 errors or Pointer errors.
  This APAR changes the message text to clarify differences T2
  errors or Pointer errors.

  ****************************************************************
  MSGFABP1520W is issued by HD Pointer Checker, when T2 errors or
  Pointer errors are detected.
  Before this APAR, the message text was
  "POINTER AND/OR T2 ERRORS WERE DETECTED DURING POINTER-CHECKER
   EXECUTION"
  The text did not tell only T2 errors were detected or
  Pointer errors were detected.
  
  The message text is changed by this APAR as follows:
  - When only T2 errors are detected, the text of MSGFABP1520W is
    "T2 ERRORS WERE DETECTED DURING POINTER-CHECKER EXECUTION".
  - When Pointer errors are detected, the text of MSGFABP1520W is
    "POINTER ERRORS WERE DETECTED DURING POINTER-CHECKER
    EXECUTION".

  The documentation is modified as follows:

  IMS High Performance Pointer Checker for z/OS, V2R1, User's
  Guide Volume 1
  (SC18725701)
  ==============================================================
  APPENDIX1.13.1.3.196 FABP1520W
  ----------------------------
  Change the description as follows:
     FABP1520W { T2 | POINTER } ERRORS WERE DETECTED DURING
         POINTER-CHECKER EXECUTION
  
  Explanation:
    If message text shows "T2 ERRORS", one or more of databases
    contain unknown data (T2) more than the threshold values
    which are specified by T2NUM and T2LEN. In this case, pointer
    error is not detected.
  
    If message text shows "POINTER ERRORS", one or more of
    databases have pointer errors. The databases are probably
    damaged. In some cases, T2 errors are also detected.
  
    Error messages are printed in some of the HD Pointer Checker
    reports.
  
  System Action:
    Processing continues with RC= 2 or 4.
    Return code 2 is returned when only T2 errors are detected.
    Return code 4 is returned when Pointer errors detected,
    or both Pointer and T2 errors are detected.
  
  Programmer Response:
    If database has "T2 ERRORS", consider reorganize the database
    for removing the unknown data.
    If database has "Pointer ERRORS", determine the causes
    of the error messages. Repair the database, if necessary.
  
    After the database reorganized or repaired, rerun the HD
    Pointer Checker job.
  
  Problem Determination: See Appendix B.
