Tuning MySQL 5.6 configuration – Webinar followup

We had a wonderful time during the Sept. 25 webinar, “MySQL 5.6 Configuration Optimization,” and I got a lot more questions than I could answer during the hour. So here is a followup with answers to the most interesting questions you guys asked. (You can also watch a recording of entire webinar here.) Q: What […]

MySQL 5.7 multi-source replication

Recently Oracle announced several new features for the latest available development version of MySQL that is 5.7.2 at the time of writing this article.

InnoDB performance optimization basics (redux)

I recently stumbled upon a post that Peter Zaitsev published back in 2007 titled “Innodb Performance Optimization Basics.” It’s a great post and reading it inspired me to examine what’s changed in the nearly six years that have followed in terms of MySQL, Percona Server – as well as in all of the other now-available […]

MySQL Security Webinar: Follow-up Q&A

Thanks to everyone who attended last week’s webinar on MySQL security; hopefully you’ve all gone out and set SELinux to enforcing mode if you weren’t already running that way.

MySQL 5.6 security vs ease of use

MySQL 5.6 surely changes the game when it comes to security vs ease of use. Before MySQL 5.6 we would get default MySQL installation being pretty insecure – the user “root” will be created with no password as well as anonymous user with limited access from local host (though still enough to cause DOS attack […]

Getting Percona PAM to work with Percona Server & its client apps

Percona Server is bundled with the PAM plugin which opens a plethora of ways to authenticate to MySQL such as restricting time when users can connect to MySQL, authenticate via a USB key, authenticate to an external authentication system such as LDAP and many, many more PAM compatible mechanisms. If you want to use PAM […]

Percona Server 5.6 Webinar follow-up and Q&A

Good news everyone! I recently presented a webinar: Percona Server 5.6: Enterprise Grade MySQL. It was also recorded so you can watch along or view the slide deck.

Replication in MySQL 5.6: GTIDs benefits and limitations – Part 2

The main benefit of using GTIDs is to have much easier failover than with file-based replication. We will see how to change the replication topology when using GTID-based replication. That will show where GTIDs shine and where improvements are expected. This is the second post of a series of articles focused on MySQL 5.6 GTIDs. […]
