Hi,

I looking at implementing RMAN backup and recovery to disk (fast disk) on a high avail. system...so recovery time is crucial.. Anybody know how fast I might restore a full backup of a 600gig to a Terabyte database.

The machine probably will have 10+ cpus HP machine and EMC disk although the backups will probably sit on a fast SAN. There will be 12Gig of fast memory... 200,000 users...max 10,000 concurrent, 100MB io card.

IF anyone has done it...what speeds could you obtain with RMAN from Disk?

What were the best SPEED enhancing factors?? ( I know cpus, mult-channels, and memory, disk ban widths.... anymore?)

Thanks,
Brian Spears

OK, that's it. My mountain bike is coming out TODAY. I don't care if it's 10F out. There's no snow, so it won't be as fun, but that's alright.

And, Lisa, in '99 I pedalled 450 miles from Superior to Madison, WI in a week. I admit that I spent some time in Rehab afterwards for rough cartilage (I was BORN geeky, too!), but it was a blast nonetheless.

Hmmmmm...maybe I'd better set my arse on the stationary bike for a few weeks first before taking on the trails. Now I'm depressed. Thank God it's Beer Day!

Now back to your regularly schedule database problems...

Hey,
I'm calling it a day, and heading to the beach now for a 10K run since it is the high 70s where I work & likely around 70 on the beach. Point your browser at www.camzone.com and click the on the Del Mar Beach Cam link. I'll wave as I go buy in about 1 hour.

HAND!

I used to play Ping Pong with the sysadmins and the app architect... aahh, the glory dotcom days when I could bring my dog to work :)

Most of the dba's I have met are not into physical activity and exercise.
