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 not setup to use the Yum priorities method of repo weighting.

So, if you see this after installing the repo via the instructions on their site:

The Percona Live MySQL Conference and Expo 2013 is almost 1 month away. It's time to start planning, set the expectations, and decide what to attend. This post will give a roundup of some of the sessions that I recommend attending and I look forward to.

First, the unexpected!

After much talk and disbelief, here they come! Oracle engineers will participate to the Percona Live conference. This is wonderful! Their participation was requested by the organizers, by the attendees, and by community advocates, who all told the Oracle management how important it is to be in this conference. Finally, they have …

On Thursday, I will travel to Boston, MA, to attend the Northeast LinuxFest, which includes also an edition of the Open Database Camp. The events will be at one of my favorite places on earth: The Massachusetts Institute of Technology, a.k.a. the MIT. Every time I speak at an event there, I feel at home, and I look forward to be there once more.

The Open Database Camp is organized, as usual, with the formula of an un-conference, where the schedule is finalized on the spot.

There are a few ideas for sessions. I have proposed two of the topics I am most familiar with:

Canonical has just announced that the Ubuntu Developer Summit will no longer be face to face and every six months. Instead it will be entirely online and virtual, using Google Hangouts. (Here is the announcement.)

On the surface, this seems like a good idea: It's cheaper monetarily, it appears to open things up to people who are unable to travel, and it makes it easier to make complete records.

However, I think it's a bad idea, for several interrelated reasons.

Some decision making needs face-time to happen. For whatever reasons, internet-only communication is not enough for a good enough "meeting of the minds" for sticky or subtle engineering and design decisionmaking.

The IETF, who probably have the longest history of any organization ever of online internet-enabled …

This month is a special month. It’s not because of President’s Day or even the exciting day where we revel in groundhogs. No, this month is special because the free book give-away is happening again. This is where you, the reader, gets to win something free for doing nothing more than posting a comment saying that you want a copy of my recently published book – The InnoDB Quick Reference Guide from Packt Publishing. The book is a great reference for DBAs, PHP, Python, or Perl programmers that integrate with MySQL and want to learn more about the InnoDB database engine.

So, all you have to do is post a comment here saying that you want a copy and write out a single (or more) sentence about how you use InnoDB in your development or production environment. At the end of the month two readers will be chosen via a random list sorting script that …

SkySQL and Monty Program are on the road with our joint Meetup in Amsterdam where Monty Widenius - the origninal creator of MySQL - will unveil his vision of the future of the MySQL database via MariaDB.

I’m pleased to announce that my first book, the InnoDB Quick Reference Guide, is now available from Packt Publishing and you can download it by clicking here. It covers the most common topics of InnoDB usage in the enterprise, including: general overview of its use and benefits, detailed explanation of seventeen static variables and seven dynamic variables, load testing methodology, maintenance and monitoring, as well as troubleshooting and useful analytics for the engine. The current version of MySQL ships with InnoDB as the default table engine, so whether you program your MySQL enabled applications with PHP, Python, Perl or otherwise, you’ll likely benefit from this concise but comprehensive reference guide for InnoDB databases.

Here are the chapter overviews …

“With MySQL 5.6, developers can now commingle the “best of both worlds” with fast key-value look up operations and complex SQL queries to meet user and application specific requirements” –Tomas Ulin. On February 5, 2013, Oracle announced the general availability of MySQL 5.6. I have interviewed Tomas Ulin, Vice President for the MySQL Engineering team [...]
