How to install MySQL 10.0.6-MariaDB and to compile lib_mysqludf_preg on CentOS 6.4
+0 Vote Up -0Vote Down

In short, during an optimization or a MySQL query involving a lot of replace(replace(replace…))) I decided to compile PREG as lib_mysqludf_preg from UDF Repository for MySQL in a view to use PCRE functions directly in MySQL.

Too bad MySQL still cant not use functions for index creation, but this is not the theme of this post.

So, fist install MariaDB 10.0.6:
set the MariaDB 10.0.6 repo, I used the ftp mirror at ftp.ulak.net.tr

How to Enable MySQL Event Scheduler
+0 Vote Up -0Vote Down

You may think that you already know what's the opposite of "DISABLED", but with MySQL Event Scheduler you'll be wrong.

In fact MySQL Event Scheduler may have three different states[1][2]:

DISABLED -  The Event Scheduler thread does not run [1]. In addition, the Event Scheduler state cannot be changed at runtime.
OFF (default) - The Event Scheduler thread does not run [1]. When the Event Scheduler is OFF it can be started by setting the value of event_scheduler to ON.
ON - The Event Scheduler is started; the event scheduler thread runs and executes all scheduled events.

So if you're going to find it in the DISABLED state …

On operating system upgrades and a packager’s nightmare
+1 Vote Up -0Vote Down

A fairy tale

Once upon a time I did an operating system upgrade, a minor one that should do no harm, but just get me up to date by fixing any bugs in the version I had been using. It seemed like a good idea.

All seemed to be fine. I use a package provided by an external vendor and not the one produced by the operating system provider as this vendor provides a newer version of the package and I need that. The vendor has to make his package fit in the os environment his package is built for and normally does a pretty good job.

I use automation to build my systems and when I built a new one some issues …

How to fix the Percona repo failure when installing Percona Toolkit
+0 Vote Up -0Vote Down

Here’s a solution to the not-so-long-standing issue of the Percona yum repo being broken for the CentOS 6 x86_64 version of the Percona-toolkit package. The repo listing is reporting an older version of the RPM which is not available on the site, so to fix this you just have to download the newer file and tell yum to add it locally. The side benefit is that you can use Yum to manage the RPM without adding the Percona repo, since the default settings for their repo could/have/had caused conflicts with Base Repo versions of MySQL packages; the Percona repo instructions set ‘enabled=1′ — not a great idea if you’re …
