Notes on Learning MySQL (as an Oracle DBA)

So how does an Oracle DBA go about learning MySQL?
Obviously you start by reading the docs. Specifically, I looked for the MySQL equivalent of the famous Oracle “Concepts Guide”.
Unfortunately, it doesn’t exist. I couldn’t find any similar overview of the architecture and the ideas behind the database. The first chapter of “High Performance MySQL” had a high level architecture review, which was useful but being just one chapter in a book, it lacked many of the details I wanted to learn. Peter Zaitsev’s “InnoDB Architecture” presentation had the kind of information I needed – but covered just InnoDB.

Wherever I May Roam

Laziness and a severe addiction to yak shaving conspire to constantly make me tweak configurations and hack scripts to make my everyday editing / shell / development experience as holistic as possible. Unfortunately the same laziness, combined with my constant hopping between home and work computers, severely gets in the way of effectively using those optimizations. Indeed, although I have those nifty toys installed here and there, because they are not uniformly installed everywhere I constantly find myself using the machines’ functional lowest common denominator. To fix that, I’ve began to dump all my environment’s custom configurations, plugins, tweaks and hacks on Github. That way, I can import my whole baseline toolbox on any given box with a simple line….

Silent Installation of Enteprise Manager Grid Control 11g

One of the first questions that I asked myself when EM GC 11g came out is how would a silent installation go especially taking into account the use of WebLogic server as the http server. But before any attempt of silent installation I started the GC 11g GUI installation to local VM machine
(Oracle Enterprise Linux 5.4 64-bit) with an allocated 2Gb of memory and got errors since WebLogic server was not installed there.

Cloning Oracle Home from RAC to Stand-Alone

I cloned Oracle software before and it is a simple process: tar $ORACLE_HOME, copy the tar file to the new server, untar, run the cloning script which will register the new home with the inventory, and you are done! In theory, at least. Here is what actually happened:

Shuck & Awe #4: Hunting for Perl

Curtis Jewell followed up on an old post by Adam Kennedy and checked out if shuffling things around really improve compression. From the results, there seems to be very little blood to be squeezed out of that stone. jjore came up with a very clever hack to stop the debugger when a test fails. Not only it is extremely useful, but the hack itself provides a lot of insight and food for thought for anyone attracted to the dark arts of under-the-Perl-interpreter-hood meddling.

BAAG, Best Practices and Multiple Choice Exams

Even though all of us DBAs come from a wide variety of cultures, I’m willing to bet that every one of us had to work his way through a multiple choice test. If you ever took an Oracle certification exam, you know what I mean.
