Good day,
We're doing the PeopleSoft upgrade thing which includes an upgrade from Oracle 9i to 10G Rel2.

Our environment will be Windows 2003 with RAC 10G.

As part of the upgrade I see from the Oracle Docs that Oracle recommends using ASM. I've been reading researching and testing on a smaller machine getting read for the new hardware.

I'm to the conclusion that ASM would only help with the disk rebalancing feature. The environment is only 1 database on RAC so provisioning does not buy me much from my point of view. Yes I understand that ASM is RAW, like RAW or whatever. However if I wanted to get RAW like performance then I could just use RAW.

Yes, there is a question in this rant.

Are the rewards of ASM appreciable enough for me to implement it on the new system?

If I do ASM on RAC should I do ASM in the non clustered test environments just to be consistent.

Do you have any feedback on your production ASM experiences?

Thanks for any feedback.

Steve
