PM44385: ABEND878-14 RUNNING ANALYZE ON LARGE AREA AND ABEND0C7 IN HFPA5T20

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ABEND878 RC14 running ANALYZE upon a very large Area.
  The ABENDS878 is caused by R9 having a negative value on the
  GETMAIN being attempted. It seems to fail after the ANALYZE for
  the area is complete, however no report comes out.
  Another symptom is an HPFP ABEND3006.
  
  Additional issue addressed: ABEND0C7 in HFPA5T20
  processing large AREA with ANALYZE command.
  
  Keywords: S878 S0C7 ABENDS0C7
  
  This is a forward fit of IMS High Performance Fast Path
  Utilities V320 APAR PM20699.

  First two items are Forward Fit APAR of HPFPU V3R2 FPA PM20699.
  1.FPA ANALYZE stacks CI RBA information in the internal table.
    When all entries of the table consumed, then the table will be
    expanded by GETMAINing extended table.
    The GETMAIN failed with S878 system code due to the negative
    value of storage size to be obtained.
  2.FPA ANALYZE(HFPA5T20) got the system exception when it
    calculates the standard deviation of the total number of IOVF
    used CI.
    This abend0C7 occurs when the total number of "IOVF used CI"
    and the total number of "DOVF used CI" are greater than
    100000.
  3.When Indexbld function builds a HISAM secondary index
    database, a delete byte field in a pointer segment in ESDS
    overflow dataset can be not cleared correctly.
    The pointer segment that has just been inserted by Indexbld
    function can be treated as the deleted pointer segment.
  4.When Analyze function verifies the secondary index databases,
    the pointer segment that is not deleted can be treated as the
    deleted pointer segment.
    Then Analyze function can show that the pointer segment is not
    found.
  5.ODE(Online Data Extract utility) ends the job step when an
    area-specific error is encountered though
    PROC_AFT_ERROR=NEXTAREA is specified in FPXIN after applying
    APAR PM17825.
  

Problem conclusion

• 1.The internal table will be extended every time when all
    entries of the table consumed.
    The total number of entries is saved in the half word field so
    that the number can be up to 32,767 represented by half word
    signed binary.
    When the increased number is greater than 32,767, then half
    word overflow condition happens and the obtained value form
    the half word field come to be negative value.
    Thus GETMAIN failure with S878 happened.
    HFPA5XT0 has been modified from LH/STH to L/ST to load/store
    from/to full word field.
  2.HFPA5T20 did not prepare the field to square the total number
    of "IOVF used CI"(PL5). It is modified to use the field
    defined with PL10 to square.
  3.The delete byte field in the pointer segment has been cleared
    correctly.
  4.The value to check whether a segment is deleted or not has
    been modified from X'80' to X'C0'.
  5.FPXDTER0 has been modified to refer the valid internal block.
