If the two systems are the same architecture and OS, this can work, but in order to get a consistent copy, you need to either: a) Stop (completely shut down) the source database while the copy runs, or b) Use volume management and take a snapshot of the source database, them copy the snapshot over. This will lose open transactions but will be otherwise consistent. -Doug ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
