RE: data block waits

Hi Jack,

That's good. It reflects the amount of time that you have spent using the CPU to do productive work, rather than waiting.

Hi Steve,

Thought I'd run it in my databas eas well.

What does "CPU used by this session" mean, it's very high compared to the other events?

Hi Ruth,

Try running the system_times.sql script from the Ixora web site. If 'buffer busy
waits' is near the top and represents a significant proportion of the total times, then you may have correctly identified the problem.

Dear Listers,

When I query v$waitstat I get a large number for the class data block and my database is running very slowly. Are these two things related and is there anything I can do?

As always, thank you for any light you can shed.
