Saying What You Mean

Ah, the perils of working in a shared, client environment. One client has us using a login that is not exclusive to us. I prefer using bash; the client is set to use zsh. This is not a problem in and of itself. However, there is a section in the .profile that is causing me issues, let me show you.

Hating MySQL for the Wrong Reasons

In Spotting the Wolf in Sheep’s Clothing, Frank Mash writes about a specific person who is spreading fear, uncertainty and doubt about MySQL. Now, this always gets me, especially with MySQL. For how long will MySQL be the bastard stepchild of the database world? Because really, it’s been a full-fledged DBMS for at least 5 years.

Stabilize Oracle 10G’s Bind Peeking Behaviour

I wrote this post because I feel there is a great need for it. The number of people struggling with unstable query plans due to bind peeking in Oracle 10G is enormous, to say the least.

Using RDA 4.11 in a RAC Environment
