  ****************************************************************
  The Installation Exit Parameter List
  was increased from 256 to 512 bytes
  in PK71816 for data encryption.
  
  User-exits for editproc, validproc,
  data compression, fieldproc, and data
  encryption use the Parameter List.
  
  For cases of editproc, validproc, data
  compression and fieldproc exits, the
  storage of the Parm list was 256 bytes.
  
  Some exits, such as DB2 Encryption tool
  expected 512 bytes from DB2 in all
  cases. Storage overlay occurred on
  encryption for editproc, fieldproc,
  validproc, or data compression with
  these exits.
  

Problem conclusion

• DB2 increased the parameter list size for editproc,
  validproc, fieldproc, and data compression routines
  to 512 bytes.
