Un-maned Failover Operations

I have video of two MySQL servers (one master, on slave) failing over from Master to Slave.  The Master becomes the Slave and vise-verse with the slave becoming read-only.  Next some load testing and then I’ll post how I did it with FREE software.

Good news to all of you who are going or were thinking of going to the Percona Live MySQL Conference and Expo. Yesterday two great addon events were announced, both happening on Friday April 13th, right after the main conference:

Benjamin Wood talks at the Dallas MySQL Tech tour on the history of MySQL

The first MySQL Tech Tour in Dallas is over. A capacity crowd filled the room. Only a few had never had ‘hands on’ with the MySQL database and very few were comfortable source code readers. The majority came to hear about embedding MySQL, how to tun systems for better performance, and some new features in the product.

Benjamin Wood started with a presentation on the history of MySQL and the changes in the product over the last few releases. Craig Sylvester showed how to use embedded MySQL. Then Benjamin capped off the event with a presentation on database monitoring and performance tuning. The event did go slightly over scheduled time due to an extended question and answer period following the presentations.

Thanks to all who attended.

This is a cross-post from my personal blog. Are you involved with an open-source project that’s interesting to MySQL users, such as Nginx, PHPMyAdmin, Drupal, Jenkins, PHP, and so on? Percona just published the application form for dot-org groups to have a free expo hall booth in the Percona Live MySQL Conference in April. Please submit your applications now, and tell your friends about this, because a) the schedule for applying is very short, and b) space is limited.

For those of you who don’t know what this is, it’s another of the O’Reilly traditions we’re trying to continue. (We are trying very hard to make this event as close to a clone of O’Reilly’s as we can.) It’s a free …

In my set-ups I have different MySQL versions (MySQL 5.0, 5.1, 5.5 and 5.6, Percona Server 13.1 and 24.0, MariaDB 5.2.10, 5.3.3, Galera 1.0, 1.1 and 2.0) running in parallel at the same time.
Up to now I have not found a practical way yet to do this with RPM or DEB packages. If anybody knows how to do it I am happy to hear about it.

So I love and need only binary tar balls. Installation and removal is done within seconds and no remainings are left over after a removal. To operate the whole I use myenv.
Some software providers unfortunately do not provide binary tar balls at all or not in the form I …

In my day job at SkySQL I work with Drupal as our content management system.  One thing we often need to do is provide a way for people to sign up for events and the like.  One such event is the upcoming SkySQL and MariaDB: Solutions Day for the MySQL® Database and unlike other events we needed to take into account the dietary requirements of those wishing to attend.

For events registration we use the Signup module and use a theme template function to provide a set of standard fields.  The code looks something like this:

function ourtheme_signup_user_form($node) {
  $form = array();
  // If this function is providing any extra fields at all, the following
  // line is …

Henrik has already posted it over on the Drizzle Blog, but I thought I’d give a shout out here too.

We’re holding a Drizzle Day right after the Percona Live MySQL Conference and Expo in April. So, since you’re all like me and don’t book your travel this far in advance, it’ll be easy to stay for the extra day and come and learn awesome things about Drizzle.

I’m also pretty glad that my employer, Percona is sponsoring the event.

I’m scheduled to deliver several free MySQL webinars via Percona and ODTUG in the upcoming weeks. I hope you can join me:

• February 16 – Verifying Replication Integrity with Percona Toolkit via ODTUG.
• February 22 – EXPLAIN Demystified via Percona.
• March 14 – Optimizing MySQL Configuration via Percona.
