I think using OEM to browse AWR data at all required diagnostics pack.

In fact, I think looking at AWR data through any tool (custom built or otherwise) requires diagnostics pack.

No dba_hist_* views for you! :)

As everything in DBA World, it depends. I do like GC (10.2.0.3) for the ability to easily browse through its AWR-like repository to show me what happened in the DB days, weeks, or months (if one manages to find how to configure GC to extend the repository from its default values) ago. And, more importantly, *who* was running that particular statement that caused whatever issue. I just used this to see that we've been having significant library cache latch issues on Saturdays going back to at least April.

The downside is of course that GC never notified me of those latch contentions in the first place. See one of my rants at http://www.freelists.org/post/oracle-l/Extent-allocation-time-process-check,4   As an aside, those notifications do seem to require the Diagnostics Pack...

Sure, I could code something similar to the repository browsing, but I have other fun functionality to rewrite/workaround. :)

Enjoy!

Rich
