As OOW approaches. I want to re-share some of my trivia/coincidental facts about Oracle with you; some have heard this before.
It seems to be assumed that fixed-point values, DECIMAL and NUMERIC, in MySQL are not susceptible to rounding errors because they are exact numeric data types. It must be kept it mind, that there are limits in precision, and the maximum number of digits for DECIMAL is 65. What I am discussing here is rounding error.
This is my first Oracle OpenWorld in a few years. I have not changed (I don’t think), but the show must have grown significantly. With the huge number of acquisitions over the past few years, I am sure I will not recognize some of the solutions mentioned in many presentation billboards as I pass through all the conference venues.

Integrated and Turnkey solutions are the name of game these days. Solutions based on software, hardware, storage, and networking tightly knitted in one box with the option of customization are shaping the future.

Today was a busy day in the news for Pythian, as Oracle released Oracle Database Appliance. Pythian is now offering fixed-price services to migrate to ODA and support it on an ongoing basis. Small and midsized business can leverage Pythian’s Oracle expertise and take full advantage of the cost and performance advantages of ODA.
I’m an experienced Oracle DBA, I have lots of Linux experience and scores of RAC installations under my belt. I also work for one of the best and more experienced RAC teams in the world. So when a customer asked how long it will take to install 2-node RAC, we answered “2 hours”. It took over 30 hours…
Oracle Database Appliance (ODA) is in many ways similar to an Exadata quarter rack: they both use two similar compute servers in an engineered system configuration, with shared storage and flash storage. But in other ways, especially networking and storage, they differ significantly.
I’ve started putting together some information about the Oracle Database Appliance in question-and-answer form. If you have an unanswered question, ask away in the comment section in this post.
