I started this post with the intention to write about what I expect Oracle to announce at this OpenWorld and it seems like the most important announcements happen at tonight’s keynote. I hasn’t been at the Oracle ACE Directors briefing so unlike them, all I can say is pure speculation-based and my wishes of what should be covered.
I was looking at the Exadata page on OTN and noticed something interesting: instead of the “Sun Oracle Database Machine”, it’s now headlined as the “Oracle Exadata Database Machine”.
What do Exadata & Team Oracle have in common? Extreme performance! Join Pythian’s Marc Fielding and LinkShare’s Mike Aldrich for Implementing Exadata – A Case Study and you’ll find out how on Monday September 20th at 12:30pm PST. You could be the lucky attendee to win the experience of a lifetime, a 45-minute flight with Team Oracle in Oracle Challenger, featuring Sean D. Tucker, the world’s premier air show performer.
This is just a quick post to note that I’ve corrected my blog on Storage Indexes here, after a follow up blog from Kerry Osborne indicating an error on my part.
Welcome to the third installment of a series describing the Oracle Exadata platform. In part 1 we talked about hardware components, and in part 2 went on to discuss software. We now move on to how these components are packaged and licensed.
As part of my preparation for the Exadata OCP Exam, I was reading through the “Oracle® Exadata Storage Server Software User’s Guide”. I found the two famous events in the Exadata world, “db file scattered read” and “db file sequential read” that cause so much confusion, have been renamed to “cell multiblock physical read” and “cell single block physical read” accordingly. Hopefully Oracle will port those events’ names to the RDBMS world as well in version 12c.
As I work on putting together slides, I’d like to remind you all of my Oracle OpenWorld 2010 presentation, a customer case study migrating a complex data warehouse environment to Exadata. I’ll be presenting along with Michael Aldrich of LinkShare and Aiman al-Khammash of Oracle, and focusing on our own experience with Exadata, lessons learned, and advice for others choosing to implement Exadata.
As a follow up from my previous post on Exadata Design, where I question the use of dimensions for certain attributes in data warehouses, I figured I should test whether HCC works with tables that have more than 255 columns, It does. Here’s my test case.
As of this afternoon, version 22.214.171.124.1 of Oracle’s Exadata storage server software, is out in the wild. This is the first publicly available version of the 126.96.36.199 branch, a major release including a full OS image with an update to Oracle Enterprise Linux 5.5. A number of bugs causing cell server crashes and hangs have been fixed, including 9472035, 9870117, and 9722560.
