While I suspect that Oracle will continue to pledge an open Java community, I highly doubt that Oracle will give up their controlling interest in the Java community. That said, I expect that Oracle will make some changes to at least give the perception of improved openness and willingness to work as part of the whole Java ecosystem.

With MySQL, after all the grief that Oracle took from the EU, I suspect that Oracle will simply pledge to continue to support and develop the open source database. After all, MySQL is a $1 billion asset for Oracle that can and will yield present and future returns for Oracle and its shareholders.

Same goes for Solaris. As Oracle has long had a working relationship with the UNIX operating system and there are many global customers that will continue to remain customers. Solaris 11 will come out under Oracle's  leadership and it will be just another option next to Oracle's Enterprise Linux giving customers a choice.

The real challenge will come to Oracle's new combined salesforce. It will be interesting to see how compensation and incentives will be meshed to push one technology over the other and if in fact there will be a combined salesforce.  Other big companies like IBM and HP have a similar dilemma pushing  both open source and proprietary applications -- so Oracle's challenge is not a unique one.
