We are getting a new 3rd-party system and the default init parameters specify recovery_parallelism=6 and log_parallelism=6.

I've never used these parameters, and am not sure if they are necessary. From the docs, it says to increase log_parallelism if you have more than 16 processors. It doesn't really have a recommendation for recovery_parallelism.

Our system is 9.2.0.5 on AIX 5.2. We only have 4 processors.

Has anyone used these? Any recommendations?

Thanks!
Jodie
