PK22604: ABEND878 RC14 RUNNING FABADA5

APAR status

• Closed as program error.

Error description

• ABENDS878 RC14 running FABADA5 due to a huge DEDB record in the
  user DEDB area. FABADA5 could not handle such a large record,
  therefore the routine will be adjusted to handle larger records.
  
  This is a forward fit of V2.1 APAR PK22094.

  Forward Fit APAR of HPFPU V2R1 PK22094.
  FABADA5 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.
  

Problem conclusion

• 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 from the
  half word field come to be negative value.
  Thus GETMAIN failure with S878 happened.
  
  Following total number of entries fields defined in DA5WRKG0
  has been changed from half word to full word to avoid overflow
  condition.
  
  * RTTBL:  No. ROOT I/O TABLE ENTRIES
  * IOTBL:  No. REC. I/O TABLE ENTRIES
  * SYTBL:  No. SYN. I/O TABLE ENTRIES
  
  Following field of DSECT in DA5WRK20 to map above field has been
  changed from half word to full word.
  
  * DDTBL:  NO. TABLE ENTRIES
  
  DA5XTBL0 has been modified from LH/STH to L/ST to load/store
  from/to full word field.
  
  FABADA5 and DA5MAIN0 have been modified just to reflect latest
  APAR number.
