Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• HD Pointer Checker issued MSGFABP2036E erroneously to correct
  a data base, when SYMIXCHK=YES or SYMLPCHK=YES is specified
  in the PROCCTL data set.
  .
  This error occurs when a database is referred by
  symbolic pointers and the database also has symbolic
  LP pointers that refers to the other database.

  *                       2. There is a root segment pointed     *
  *                         by a symbolic logical parent (LP)    *
  *                         pointer or a symbolic index pointer. *

  *                          the root segment has a logical      *
  *                          child segment. And, the logical     *
  *                          child segment has a symbolic LP     *
  *                          pointer to a root segment in        *
  *                          another database.                   *

  ****************************************************************
  When HD Pointer Checker creates pointer records for the symbolic
  pointer check, it does not clear the key area in the records.
  If it creates a record with a shorter key length after a record
  with a longer key length, the key value of the previous record
  remains in the I/O area. This causes an erroneous MSGFABP2035E
  or MSGFABP2036E.
  

Problem conclusion

• The modules FABPSDA0 and FABPSHI0 have been modified to set
  correct root key value on the pointer record.
