In recent past I’ve blogged few scripts which use specially crafted ordered nested loop for sampling contents of V$ and X$ views fast, with plain SQL.
If you haven’t read them yet, here are the links:
I wrote the above scripts having special purposes in mind (e.g. profile session waits or latching activity).

Modify partitions without invalidating dependant objects. October 2007 (updated August 2008)
A number of recent threads in the Oracle-L list have made it pretty clear that Automated Workload Repository (AWR) is a tool that you are expected to use when troubleshooting a database problem.
Never mind the fact that AWR is still a product that is licensed separately from the database, and that a large segment of the Oracle DBA population doesn't seem to realize that. Or that Active Session History (ASH) is part of AWR, and falls under the same license restrictions.
So I conducted a poll regarding the use of AWR. AWR Usage Poll. If you haven't in the AWR Poll, please do so.
While the web site does provide a chart of results, those results don't include the extra comments made by poll takers. You may are may not be able to download all the results, I'm not sure if that is restricted to the poll owner.
I got a question regarding Metalink note 296235.1 about a describe bug which causes objects to “disappear” when they are described when database is not open.
It was an interesting case involving a bug, so I wrote a quite long analysis with test cases today. However when posting the entry to wordpress, it managed to completely mess up the formatting. After wasting half an hour trying to get the formatting correct I gave up and saved the article into a PDF instead.
