Implementing Exadata: The results are in

Following up on my earlier webinar Implementing Oracle Exadata – Strategies for Success, I’ll be giving another webinar to present the results of the Exadata implementation at LinKShare. I’ll be talking about actual performance results, our zero-downtime go-live, compression experiences, and performance tuning in an Exadata environment.

Lucky Winners of the Exadata Flight Giveaway

Congratulations to Chris Marlowe of Oppenheimer Funds and Bill Mitchell of Alliant Energy, attendees to my Exadata session yesterday. Both are lucky winners of the a flight with the inimitable Sean D Tucker and the Oracle Challenger. For those of you who missed the session, keep your eyes on this blog for a recording, coming soon.

Self-Contained Oracle Patchsets: Finally!

With the release of the 11.2.0.2 patchset, Oracle has stopped releasing sets of individual patches, but instead is packaging it as a self-contained, complete software install. I can see many benefits to this method, and quite frankly am wondering why it took so long to come about.

A Grand Tour of Oracle Exadata, Part 3

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.

Exadata Customer Case Study at Oracle OpenWorld

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.

Exadata storage server software 11.2.1.3.1 released

As of this afternoon, version 11.2.1.3.1 of Oracle’s Exadata storage server software, is out in the wild. This is the first publicly available version of the 11.2.1.3 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.

Oracle feature request #94739: CTAS optimizer statistics

en creating an index, Oracle versions 10g and above automatically compute optimizer statistics. And even before that, 9i had a COMPUTE STATISTICS clause to accomplish the same thing. Not only does it save the time and effort of running DBMS_STATS, but it also saves the disk I/O involved in such an operation, since all rows are available in the course of index creation.

Exadata TPC Benchmarks

I’m not aware of any TPC results for Exadata V2. However a TPC-C test was run in late 2009 using a Sun F5100 flash array on Sun T5540 servers, setting a record for the benchmark that still stands. The Oracle wiki has a great overview of the various benchmarks and what they actually measure.
