Dell and HP To Sell Oracle Operating Systems
angry tapir writes "Oracle has announced that rival hardware vendors Dell and Hewlett-Packard intend to certify and resell its Solaris and Enterprise Linux operating systems as well as Oracle VM on their x86 servers. The announcement 'demonstrates Oracle's commitment to openness,' company co-president Charles Phillips said in a statement."
If you need good MVCC (busy OLTP environment shared with reporting, long-running transactions, multi-table reports, etc.), I'd recommend Firebird (or Interbase) or PostgreSQL. Interbase essentially pioneered MVCC. My experience with both Oracle and MS-SQL has been that they didn't really grok MVCC very well, and their hacks to back-port it aren't nearly as good as a DBMS built with it in mind. Oracle requires that you preconfigure INITRANS "just right" and it's not pretty if you don't. MS-SQL doesn't really push that it even supports transactions, let alone MVCC, though it does (2005 was messy, 2008 does a little better;) by default, MS-SQL still uses the writers-block-readers model. When I talk about MVCC, Oracle and MS-SQL DBA's usually don't even know what I'm talking about.
