Innotop: A real-time, advanced investigation tool for MySQL
+2 Vote Up -0Vote Down

GUI monitoring tools for MySQL are not always suitable for all our needs or situations. Most of them are designed to provide historical views into what happens to our database over time rather then real-time insight into current MySQL server status. Excellent free tools for this include Cacti, Zabbix, Ganglia, …

Why you should register for MySQL 5.6 certification exams now
Employee +3 Vote Up -0Vote Down

I’ve previously shared my excitement over the coming Oracle Certified Professional exams for MySQL 5.6 (both Developer and DBA), and I’m putting my (employer’s) money where my mouth is – I’ve registered to sit for the DBA exam in early November (some test sites have limited opportunities; interested candidates should consider booking now).  Here’s why I think others should do the same:

Low cost

During the beta period (through December 14), the cost of the exam is only $50 …

Creating custom rules in MySQL Enterprise Monitor
Employee +3 Vote Up -0Vote Down

Quite some time ago, I published scripts to implement password policies for MySQL, and promised to show how to expose violations of that policy via MySQL Enterprise Monitor (MEM).  That stalled somewhat with other objectives, but I want to revisit it now that MEM 3.0 is GA.  If you haven’t tried MEM 3.0 yet, consider doing so – it’s …

MySQL 5.6 Configuration Optimization Webinar, Sept. 25
+1 Vote Up -0Vote Down

This Wednesday in our next webinar I’ll share how to configure a better-performing MySQL 5.6 server. You’ll lean a practical approach to generating a sensible configuration file that sets what is needed and omits what is not.

Why dedicate an entire webinar to the new configuration settings within MySQL 5.6? Mainly because the default configuration files that come with MySQL 5.6 are not …

New MySQL 5.6 Developer Certification Exam
Employee +4 Vote Up -0Vote Down

You may have already seen the news: Oracle is launching an updated certification for MySQL Developers, based on MySQL Server 5.6.  This is exciting to me for several reasons that I want to share:

Only one exam

Earlier versions of the MySQL Developer certification required sitting for two separate exams.  One goal in redefining the certification process was to make it more accessible to candidates, and reducing the cost – in both time and money – developers need to invest in examinations.  This obviously presented a …

Enabling crash-safe slaves with MySQL 5.6
+2 Vote Up -0Vote Down

Being able to configure slaves to be crash-safe is one of the major improvements of MySQL 5.6 with regards to replication. However we noticed confusion on how to enable this feature correctly, so let’s clarify how it should be done.

In short

1. Stop MySQL on slave
2. Add relay_log_info_repository = TABLE and relay_log_recovery = ON in my.cnf
3. Restart MySQL and relax

The gory details

To fully understand why you should change the above settings if you want crash-safe slaves, let’s first look at the reasons why replication can break when a slave crashes.

Fun with Bugs #23 - more on Optimizer bugs in MySQL 5.6
+3 Vote Up -0Vote Down

When I've sent CV to MySQL AB back in 2004 (or early 2005) I had actually wanted to become a developer there. As a person who just started to use MySQL on a regular basis and, at the same time, had to explain dozens of engineers per month how optimizers works in Oracle and Informix RDBMSes, and optimize queries for them from time to time, I was naturally interested in adding missing (but well known to me) features to MySQL optimizer (from hash joins to stored outlines, histograms and tracing, all things I've noted as extremely useful for many real life cases)... So, I wanted to work on MySQL optimizer specifically, if something related to …
