I just saw on orablogs Tug's post to his Oracle blog titled http://www.grallandco.com/blog/archives/2005/01/do_not_remember.html - (broken link) Do not remember the default password... here a list... and went over to comment but couldn't find how to comment. I wanted to concur that the http://www.cirt.net/cgi-bin/passwd.pl - (broken link) cirt default password page is excellent for covering many types of software. The page says it has passwords for 271 vendors and 1386 default passwords.
I just want to also mention here that I have
probably the biggest list of Oracle default passwords on the net. There is also a simple tool for checking your databases for existence of any of these
Oracle default username / passwords.
