I cleared the "enterprise" issue up with some Red Hat folk --
Essentially, you _could_ get every piece that made up the enterprise edition, free for the downloading.
But you'd have to go through a great deal of pain to download all the pieces and set it up properly. And even then, you wouldn't get their "enhanced" support level. Whatever that entailed...
I have no idea what happened between them & Oracle. But clearly the relationship is ice cold.
I'm not sure what they are doing with this new DB play. It looks like GreatBridge rebuffed their advance, which obviously put a kink in their strategy. Perhaps even _they_ haven't fully sorted out how this will work.
I cannot believe they'd do anything as silly as put out a "proprietary" package. But.... I've been wrong before.
