Error description

  • Due to some product changes in DB2 V9.7 FP4, LONG column data
    can be corrupted on HP platform, when several agents do writes
    and reads on the same LONG column in parallel.
    db2dart and db2inspect will not detect such a kind of
    corruption.
    

Local fix

  • Use LOB column type instead of LONG on HP platform, when
    possible.
