I always had the wish to do some investigation about Statspack and Phat on RAC. I have tried a few times to get RAC running on Vmware on my 2GB laptop, but I haven’t managed to get it working yet. But sometimes a interesting chance comes along. An important client is having some performance trouble on a RAC cluster, so this is a good moment to do some R&D, and be productive immediatly. I figured out how Statspack works on RAC, I have created 2 snapshot jobs, each with instance affinity. Now I’ll see if Phat can be of any use.
