Back when 14.4k baud modems were fast, mice were beige, IBM made PCs, and new software versions were relased annually instead of weekly, software came with useful, intiutive manuals that included tutorials for everything you needed to get up and working.
Other than the ability to take the manual in its binder to the couch to flip through, dog ear and highlight, I was happy to discover a full set of training buried in the doc folder of the Oracle Database install (and many other of their applications, though location may vary).
Even if you don’t have the full install, the 2 Day DBA and other really useful documents can be found online, too. The 10.2 version is located here: http://www.oracle.com/pls/db102/portal.all_books.
