If you get a kick out of learning Oracle internals, especially undocumented commands then check out Miladin’s blog:
His blog uses the same wordpress template as mine, but the content and authors are different!
He has also published detailed notes about Oracle diagnostic events and about some serious improvements in 11g event syntax (as the whole diagnostics infrastructure got a major upgrade in 11g).
Just beware to not run anything in your non-toy databases without seriously thinking & testing why should the feature help and whether it’s safe to use it at all. Most undocumented stuff (in anyone’s blogs, including mine) should be used only in those rare cases where conventional, documented or at least widely used methods dont help.
I got to know about undocumented commands from other sites but your site http://www.oraclue.com/ is more informative and simple to understand.
Note that oraclue.com is not my site, it’s Miladin’s (it just uses the same template as mine). My site is blog.tanelpoder.com
I have included a measure against hidden frame hijacking so now the URL bar should always show my blog.tanelpoder.com when viewing my pages. I’ve let Miladin know about the problem with his oraclue website and I hope he fixes this issue fast..
I was very fortunate to have the opportunity to work with Mr. Modrakovic for 6 months on a contract. I learned more in 1 week from Mr. Modrakovic than I did in an entire semester of grad school. I would highly recommend his blog for undocumented Oracle tips. Can not be beat for inside info. Also, always run on your test network first :o)
