Oracle Achieves Record TPC-C Benchmark
It appears that one or two of my previous posts may have inadvertently annoyed some people at Oracle, so I would like to try and make amends today by posting something extremely positive about the company which, lest we forget, made the "world’s first commercial relational database", backed Linux before it was a commercially viable option and … Continue reading Oracle Achieves Record TPC-C Benchmark
Exadata X3 – Sound The Trumpets
It's crazy time in the world of Oracle, because Oracle OpenWorld 2012 is only a week away. Which means that between now and then the world of Oracle blogging and tweeting will gradually reach fever pitch speculating on the various announcements that will be issued, products that will be launched and outrageous claims that will … Continue reading Exadata X3 – Sound The Trumpets
Database Virtualisation: The End of Oracle RAC?
A long time ago (2003) in a galaxy far, far away (Denmark), a man wrote a white paper. However, this wasn't an ordinary man - it was Mogens Nørgaard, OakTable founder, CEO of Miracle A/S and previously the head of RDBMS Support and then Premium Services at Oracle Support in Denmark. It's fair to say that … Continue reading Database Virtualisation: The End of Oracle RAC?
Exadata Roadmap – More Speculation
It's silly season. In the run up to Oracle Open World there are always rumours and whispers about what products will be announced - and this year is no different.

Why is it so hard in Oracle to get a decent answer to the question of how many seconds elapsed between two timestamps? I'm looking at DBA_HIST_SNAPSHOT and wondering how many seconds each snapshot spans, because later on I want to use this to generate metrics like Redo Size per Second, etc. SQL> desc dba_hist_snapshot … Continue reading Querying DBA_HIST_SNAPSHOT and DBA_HIST_SYSSTAT
Exadata Roadmap Preview
Last week, Andrew Mendelsohn gave a talk at the Enkitec Extreme Exadata Expo ("E4") run in Texas by those excellent guys at Enkitec. Andrew is the SVP of Oracle's Database Server Technologies group, so it's fair to say he has his finger on the pulse of the Oracle roadmap for Exadata. Big thanks to Frits Hoogland … Continue reading Exadata Roadmap Preview
Database Virtualization Part 2 – Flash Makes The Difference
In part one of this article I talked about Database Virtualisation and how I believe that it is the next trend in our industry. Databases - particularly Oracle databases - have held out against the rise of virtualisation for a long time, but as virtualisation products have matured and the drive to consumerise and consolidate … Continue reading Database Virtualization Part 2 – Flash Makes The Difference
Database Virtualization Part 1 – It’s Happening Right Now
Forget Big Data. Stop talking about Analytics. There is a trend taking place in the marketplace right now, one that is really happening rather than just being spoken about. That trend is Database Virtualisation. Or, as my U.S. cousins would spell it, Database Virtualization. (And whilst I am loath to drop the Queen's English in … Continue reading Database Virtualization Part 1 – It’s Happening Right Now
