  • Closed as program error.

Error description

  • In SQL access plans where a table is accessed at least twice,
    the DB2 server might not retain locks required to preserve read
    stability during the entire SQL execution.  Locks might be
    released for rows that satisfy matching criteria on the first
    access, and requested and held later only as the rows are
    retrieved by the application.
    
    Symptoms might include lost updates, duplicate row retrievals
    across applications, and inconsistent results within a
    transaction.
