Hi Muru >Has anyone used Oracle workspace on 9i r2? Any critical issues? There are some restrictions/requirements... - only full export/import is supported - only row level triggers are supported - you need a primary key for each table - you cannot drop versioned tables or a user containing versioned tables Since everything works with "complex" views and instead of triggers the = performance are not the best. Eventually this is no problem at all... it = really depends on what do you want to do... HTH Chris -- //www.freelists.org/webpage/oracle-l
