Hi,
I am trying to figure out performance issues on a SUN OS. I am currently running V8.1 with two instances.

I need to know what is the best way to find the CPU, IO and memory performance. I need to figure out where is the bottlenecks. How do I do this?

It's not really related to DB2, is it? You can use sar or dtrace to look at the performance from the OS perspective.

Thank you for your response.
The reason I posted it here was due to the fact that I am doing some performance tuning for DB2 on Sun.

I know there are commands like SAR and vmstat, iostat and all. But my problem is that I don't completely know how to interpret them. It will be helpful if some gives me some documentation on how to look for trouble with these commands.
