All, I'm going to start a new thread away from the Undo tablespace link because, well this is just dumb & I'm wondering how many others have heard similar things. BTW I've changed names to protect the guilty. Hello all, we had a meeting with Xxxx today about commit and rollback operation. Xxxx advices us to not use the default Oracle commit/rollback, but to use instead these two procedures : - FWD_LID.TRANSACTION_COMMIT - FWD_LIB.TRANSACION_ROLLBACK Goals of this procedure is to store in TRANSACTION_LOG table records about transaction performed. These records will be used when synchronisation will be performed between XXX online and XXX offline. It enables mechanism used to manage the synchronisation to prevent lost of data on long running synchronisation. So, now, each time a script that modified data must be executed, we must too use these two procedures to commit or rollback. Feel free to forward to other people that deals with transaction somewhere in development/database administration/...
