PK26075: HPFP REORGANIZATION SOLVES THREE PROBLEMS.

APAR status

• Closed as program error.

Error description

• Three issues being resolved:
  1. HPFP Reorg shows an incorrect DSNAME of USR with HFPJ0011I
     and HFPJ0012I in UNLOAD.
     A known symptom: Although this abend could show up
     in various unpredictable locations due to the lack of
     the LOCEPAX=YES parameter in the IEFZB505 macro, one known
     location is an ABEND0C4 in IEFQBSVA near x'86'.
  2. ABEND0C4 when the internal table is allocated at the page
     boundary.
  3. ABEND0C4 when PTRCHKLVL and ICACHE=YES in RELOAD are
     specified.
  
  Keyword: ABENDS0C4

  This APAR solves the following 3 problems.
  
  1. HPFP Reorg shows an incorrect DSNAME of USR with HFPJ0011I
     and HFPJ0012I messages during UNLOAD processing.
     HFPUDSN0 abends S0C4(ABEND0C4) when it gets DSNAME.
  
  2. HPFP Reorg gets ABEND0C4 when the internal table is
     allocated at the page boundary during UNLOAD processing.
     It occurs when ODSNMASK keyword is specified
     in UNLOAD command or OAREA=ALL keyword is specified in
     FILECTL subcommand.
  
  3. HPFP Reorg gets ABEND0C4 when PTRCHKLVL and ICACHE=YES
     in RELOAD command are specified for the AREA whose segment
     level is 2 and dependent segment has PCF pointer.
  

Problem conclusion

• 1. Because HPFP Reorg does not uses LOCEPAX=YES option of
     IEFZB505 macro that defines EPA parameter area for issuing
     SWAREQ macro with Read Locate mode to UCB above 16M. As the
     result of that garbage is set in SWQMPA (SWA control blocks)
     and SWAREQ process fails.
  
     The module HFPUDSN0 has been modified to use the GETDSAB
     macro instead of the EXTRACT macro and to add a LOCEPAX=YES
     option in the IEFZB505 macro.
  
     The module HFPWMTU0 has been modified to introduce two new
     internal error messages. These error messages are issued
     when the GETDSAB macro error or the SWAREQ macro error
     occurs.
  
  2. The module HFPLRPT0 has been modified to handle the internal
     table for the unloaded area control correctly.
     The module HFPCOFT0 has been modified to handle the internal
     table for FILECTL subcommand correctly.
  
  3. The module HFPA1RP0 has been modified to correct the LOAD
     instruction to get a RBA of the pointer in the AREA whose
     segment level is 2 and dependent segment has PCF pointer.
