Today's Oracle gem of the day comes not from one of my books, but from Perl for Oracle DBAs, borrowed from a coworker. I'll have to add it to my ever-growing library soon, though!
This book apparently describes a toolkit called PDBA which, among other things, creates a repository of your data dictionary and other structures. Version control for Oracle! Sweet! I haven't poked into it much, yet, but the book website has PDBA for download. (Is O'Reilly's Oracle section in a folder on your Phoenix bookmarks bar? It is on mine, along with all the Oracle sample chapters, the new books page, the main O'Reilly page, and even the out of print books page.)
In related news, I can't stand it when people denigrate the U.S. Postal Service. My mailman risked frozen streets last week to deliver my next package from Bookpool, even getting out of his truck in the cold and walking across my icy sidewalk to my door. Risked his neck, if you ask me. I got free shipping from Bookpool for going USPS, and I'll bet UPS and FedEx weren't even running that day. As a libertarian, I don't think it's appropriate for the government to handle this service
