PH39924: WHEN THE USEDBDS OPTION IS SPECIFIED OR AN SMS-FORMAT IC IS USED, SOME PROBLEMS OCCUR DURING KSDS OR ESDS RECOVERY.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• 1.If ADD IC or ADD PC is specified when recovering KSDS, the
  ICDS is not created correctly and the HPPC report is incorrect.
  2.If OUTPUT(BOTH) is specified, KSDS VSAM PUT error occurs in
  the copied DBDS dataset.
  3.When there are no more IC records to process but there are
  records to add from the log dataset and VSAM ESDS is blocked,
  the correct RBA of the next data set record could not be
  obtained.

  ****************************************************************
  When the USEDBDS option is specified or a SMS-format IC is
  used, the following problems exist during recovery.
  1. If ADD IC or ADD PC is specified when recovering KSDS, DRF do
  not pass the records to HPIC or HPPC. Therefore, the ICDS is not
  created correctly and the HPPC report is incorrect.
  2. If OUTPUT(BOTH) is specified, KSDS VSAM PUT error occurs
  because the copied DBDS is PUT with OPTCD(DIR).
  3. If DBDS is defined as blocked VSAM ESDS, IC has only the
  first CI and the update log exists in the CI after the IC,
  the correct RBA of the next data set record cannot be obtained
  because the calculation of current RBA is incorrect.
  As a result, the DBDS is recovered with shifting back by 1 CI.
  

Problem conclusion

• 1. If ADD IC or ADD PC is specified when recovering KSDS, DRF
  calls the API to pass the records to HPIC or HPPC.
  2. If OUTPUT(BOTH) is specified, PUT with OPTCD(SEQ) is used for
  the copied DBDS.
  3. If there are no more IC records to process but there are
  records to add from the log dataset, VSAM ESDS is blocked, and
  there are no only first CI record in the IC records, calculate
  the current RBA by CI size - Record length.
