This site is run by some of the top technical people at Oracle Corporation, including Anjo Kolk. Oracle Internals magazine, edited by Don Burleson, is a heavily technical and extremely well-edited magazine. Formerly shareware, this tool was purchased by Quest Software and is now offered in a supported, purchased format as well as an unsupported, free, 90-day trial format. It is certainly the equal of any competing product and it's free.
Registration is free.
Although you'll get a small volume of junk-email, it's worth it.
