This just in. In a long interview on Linux Voices, Oracle's Linux architect Edward Screven comments on the MySQL/Sun acquisition.
...we just don’t care. I mean, we don’t see MySQL very often, again, in competitive deals. It’s out there, but it’s not very often that a database sales rep comes back and says, “I had to compete for the business against MySQL.”
To be fair the question is about how the MySQL acquisition affects Linux. But it seems really hard to believe Oracle does not care about MySQL. This is the same company that bought InnoDB. There is no doubt that Oracle is watching developments at Sun very carefully. The interesting problem for Oracle is not simply that Sun now has MySQL. It is that Sun owns or backs a portfolio of open source databases. And there are plenty of companies besides Sun that are working to make those databases full-featured, highly available, and very scalable. Like my company, Continuent, for example.
With a small number of additional acquisitions, Sun could control the open source end of the market fully. Now that has to be a little disquieting.
