A license is the "right to use" (RTU) the software and
not the software itself. If you have a license, you can
obtain a copy of the software through whatever means -
order, download, use the CDs from your last project, etc.
Please note that Oracle doesn't use software keys. You can
just install the software and use it. It is up to you and
your consciences to license the software before using it.
No. Every EULA you'll click through will include some clause restricting usage to 30 days for evaluation purposes, except in a few cases (db client, beta versions, XE edition, Technology Network stuff, Linux etc). And they do enforce that clause as soon as they find you're using any of their stuff. Plus, you need an account on their site to download pretty much anything, so they'll know what you download, and from time to time you might get a call to see how that "reviewing" is going, especially if you are not a customer yet.
It makes it very easy for people to get access to software and to learn, however, especially if they're covered by a company who is already a customer.
How does that play with the fact these changes seem to be checked into the GPL'd code? Wouldn't GPL itself give you a separate license to use the features regardless of whatever EULA Oracle comes up with?
When reading blocked quotes like above, the iphone browser farts and cuts off the text at the right-most ending. I notice it only happens with the <code> construct, which is used regularly here.
You can download it for free on the web.
