I'd bet moderately large sums of money that Linux and Oracle on Linux don't know squat about FlashCopy, SnapShot, TimeSaver, or whatever Hitachi's version is called. Sync isn't, um, synchronous, so you don't know what it's done for you and whether stuff has happened *after* sync, so it doesn't really help that much unless you also quiesce the database (and not necesarily even then). That's my understanding, anyway. ...phsiii ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
