The short answer is: don't even try if you have multiple disks. You *may* be able to get away with it now using the parent/child job functionality that got added in 6.0 but we haven't tested this, having given up on a long time ago after a multi-year battle.
Sure, you can get it work most of the time, and many people do. However, there are many, many edge cases where this will break down, and if you do go down this route, you'll find some them eventually. You'll find cases where the bpstart didn't run or the bpend didn't run, or they'll run twice. We definitely had a really, really bright guy working on the bpstart/bpend scripts and he could not solve the problem so that it was 100% reliable. We simply wanted to put Oracle into hotbackup mode, do the backups, and take it out of hotbackup mode. Like you said, you'll be writing some logic around it. However, you'll be writing and writing and writing, tweaking it regularly as you run into all of the edge conditions and you'll cuss and swear as you stumble over them. Bottom line: it can't be done reliably. Use a different method of coordinating this. .../Ed On Jan 31, 2008 8:57 AM, Dave Markham <[EMAIL PROTECTED]> wrote: > Guys im running Netbackup 6.0mp4 and a number of oracle SSO media > servers backing themselves up.
