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.
I’ve just come across an old known issue again today. Was working in the greatest and latest 12.1.2 Oracle e-Business Suite environment. Surprisingly, I face the old issue when WF_LOCAL_ROLES and WF_LOCAL_USER_ROLES objects (among other objects) are set to NOLOGGING mode. The easiest solution is to switch the whole database to FORCE_LOGGING mode:
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.
It’s that time of the year again — Oracle OpenWorld time — and it’s my pleasure to announce our regular Oracle bloggers meetup again this year. We all know that Oracle community has grown this year so we expect to see folks from all the different technologies including MySQL, Java, Sun hardware folks in addition to the core Oracle database and apps crowd.
This week’s edition, Log Buffer #201 has been compiled and published by Craig Mullins on his Data and Technology Today blog.
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.
Michigan OakTable Symposium (MOTS) is a unique event taking place just before Oracle OpenWorld — 16-17 September. Why unique? This is the first conference (is it not?) where all presenters are members of OakTable Network, a group that gathers number of like-minded IT professionals with scientific approach to Oracle database technology and to the life in general.
