PK39461: ABEND S0C4 ( ABEND0C4 ) IN FABJFCD7, FABJFCDN8, FANFCDN9 OR FABFJCDA WHEN USING FASTIC=(,DUMP)

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When DFSMSdss reads data block after IMS logical EOF (but
  not physical EOF) and passes it to HPIC via UIM, HPIC tries to
  reblock unexpected data.  This can cause an S0C4 in
  FABJFCD7, FABJFCDN8, FANFCDN9, or FABFJCDA or some
  other unexpected result.
  

Local fix

• No work around

  This APAR fixes following problems of HPIC V4.
  
  1. After applying APAR PK37644 to HPIC V4, HPIC abends
     S0C1 ( ABEND0C1 ), when both DB record and DBDS record are
     not requester in DBRC at Image Copy function. Because HPIC
     mishandled RECON data set DCB that close it before fetching
     next RECON record. Both DBD record and DBDS record are not
     registered in DBRC with DBRC=Y is normal case. HPIC should
     not process diagnostic record and should not close DCB
     between fetching DBDS record and DB record.
  
  2. HPIC gets S0C4 in FABJFCD7, FABJFCD8, FABJFCD9, or FABJFCDA
     or creates IC data set which includes unused CI image that
     cause of pointer error for HPPC when FASTIC=(,DUMP).
     Because DFSMSdss passes logical record via UIM that beyonds
     EOF of DBDS. HPIC UIM exit handles EOF CI in a logical
     record, but has not been expected other logical block is
     scheduled by DFSMSdss after EOF, then tried to process
     unnecessary data as normal CI data then ABEND S0C4 or
     unexpected result. HPIC should ignore logical records in
     UIM after all valid CI is processed.
  

Problem conclusion

• FABJFCDN has been modified to detect the EOF of input data set
  with a new internal flag.
  
  FABJDSSB has been modified to add new internal flag which
  indicates the EOF of input data set.
  
  
  FABUARCN has been modified not to close DCB of RECON data set
  when both DB and DBDS record are not registered.
  
  FABJMAIN and FABJRCHK have been modified to distinguish whether
  HPIC should process diagnostic record or not with new internal
  flag.
  
  FABURRPD has been modified to add new internal flag which
  indicates whether HPIC should process diagnostic record or not.
  
  The following modules have been reassembled.
   FABJARC0 FABJDFC7 FABJDFC8 FABJDFC9 FABJDFCA FABJFCAI FABJFCC7
   FABJFCC8 FABJFCC9 FABJFCCA FABJFCCM FABJFCD7 FABJFCD8 FABJFCD9
