DBAs and Developers, Do you suffer from Performance Dysfunction (PD)? is a post from: Database Geek Blog

Posted by the Database-Geek.

DBAs and developers, do you suffer from PD? PD, performance dysfunction, is not a topic that many like to discuss. A few people do but they mostly hang out together at conferences and talk about the size of their tuples. For the rest of us, PD is an evil, evil thing.

Comment by LewisC on Netezza Performance Server vs Oracle Database Machine (Podcast) is a post from: Database Geek Blog

I think Phil would say that according to the Oracle page for the database machine:

Lewis,

Are we comparing apples with apples?

The Oracle database machine seems to me to be a generic machine trying to improve performance for normal, everyday usage of Oracle Database.

Oracle database includes some ROLAP functionality but is not, strictly speaking, a dedicated data warehouse database (cf HOLAP and MOLAP).

LewisC’s An Expert’s Guide To Oracle Technology

According to an article at Computerworld, Yahoo is running a 2 PB (not GB, not TB, PB – Petabyte) database that processes 24 billion events a day. Let’s put that in perspective. 24 billion events is 24,000 million events; 24,000,000,000 events. 1 petabyte is 1,000,000,000,000 bytes. Yahoo has two of those. Actually, I should be… Read the rest!

The Oracle Cost Based Optimizer: A Webinar is a post from: Database Geek Blog

Earlier today, I attended a webinar by Hotsos. The webinar, titled Cost Based Optimizer: 1 of 2, was a basic introduction to the Cost Based Optimizer (CBO) in Oracle and the 10053 trace file. The CBO optimizes SQL queries and that optimization can be seen in a 10053 trace. It was not, what I would call, an advanced webinar but was… Read the rest!
