Unless you can shut down the zLinux instance when you take your snapcopy, you will always be out of sync.

This is a little different than a straight backup. We are using a snapcopy (Flashcopy, TimeFinder, Shadowimage) to take the PIT and the Oracle control files and index are not in sync.

Works great. Several successful recoveries in a wind tunnel (DR site).

If you're using anything but an application running inside the virtual machine (eg RMAN to disk, or another app that uses the Oracle APIs to get the data), you're going to lose, and you get the problem you've observed. The virtual machine probably has loads of stuff in RAM which the disk controllers may not know about yet, so your PIT copy is missing stuff. You either have to take the virtual machine down, or do your backups from inside the virtual machine. I'd suggest the latter. --db On 8/8/10 9:38 PM, "Joseph Higgins" <[email protected]> wrote: > Hello, > > Is there any way to maintain consistency for point in time copies > without suspending the server IO? ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
