  ****************************************************************
  In the parsing processing, a storage was
  freed after the statement was processed, and
  then a new storage was obtained for the next
  statement. We use two identical storages,
  one for input and one for the output data.
  However, sometimes, we freed the wrong
  data storage, and BPE could not find the
  input storage and so an intermittent S0C4
  occurred.
  
  For the 0C4 in the index list area, the
  problem occurred when we have BLD_SECONDARY
  (select). If a primary index needs to be
  added, we need to have a larger storage to
  hold the data. And because every member in
  the recovery list shares same index list,
  we need to update every DBD with the
  pointer of the new storage, but somehow it
  was updated only for the DBD that has
  the primary index.
  
  For the IB error, the problem occurred when
  an invalid index was selected in BLD_SECONDARY.
  If the wrong index was the only one in the
  selected index list then we passed an empty
  statement to IB and so got rejected.
  

Problem conclusion

• The parsing module was modified to make
  sure that we re-use two storages that
  contain input/output data to BPE for
  processing. The storges are cleared after
  one statement is processed and get ready
  for the next.
  
  FRXVSTA2 and FRXTAU00 have been modified
  for index list issues.
