The Percona Toolkit team is happy to announce the release of Percona Toolkit versions 2.0.5 and 2.1.2. These are bug-fix releases in the 2.0 and 2.1 series, respectively. These releases fix many dozens of bugs, and we suggest that users upgrade to the latest versions of the tools.

The complete list of changes is on Launchpad for 2.0.5 and 2.1.2. Here are some highlights of the changes in version 2.1.2, which is the current development focus:

• We fixed several bugs in pt-table-sync that prevented it from working properly, and disabled the –lock-and-rename feature when using it with MySQL versions that don’t support it reliably.
• We enhanced pt-table-checksum and pt-online-schema-change to add even more safety checks, and to detect and deal with …

Percona will be at Southeast Linux Fest tomorrow and Saturday. We’re supporting the event, and we hope to meet you there. If you’ve never been, this is a great regional show that’s grown enormously in the last few years. Peter and I will both be speaking: Peter about optimizing MySQL configuration, and I will talk about inspecting MySQL’s performance and scalability via TCP packet headers.

In addition, the entire Percona Toolkit and Online Tools team (me, Daniel Nichter, Brian Fraser, and Miguel Trias) will be there. This is your perfect opportunity to meet the engineers writing the Percona Toolkit code. Direct access to the developers is a valuable chance to tell us your wishes, explain your gripes or troubles, and get help and advice on how you’re using the tools. We can also tell you what we’re currently working on and what you may expect in future releases. We …

Whenever I learn about a new technology, I typically want to know the major administrative touch points more than I want to know exhaustive detail about every configuration option.  Give me the gist, show me enough to get started, and give me a link to the manual.

XtraDB cluster (and Galera, the technology on which it is based) has been attracting a lot of interest in the community and we want to start presenting information about both what we know is essential, but also what we suspect will become essential as more and more production experience is logged with these important new technologies.

As such, I put together a baseline talk for getting you into a working knowledge of XtraDB …

I’m going to deliver MySQL Training next week (May 21-24) in London.
This is a rare opportunity as I do not personally deliver a lot of Training, especially outside of US. There are still some places left if you want to sign up.

You will also get a signed copy of High Performance MySQL 3rd edition as an attendee.

The recording and slides for my webinar on zero-downtime schema changes with MySQL are available now. Don’t miss Vadim’s webinar tomorrow!

You might have heard that Oracle made the decision not to support MySQL for IBM i any longer. This is certainly understandable. However, there are still users who want to continue running IBM i and MySQL.

That’s why we’re happy to announce that we have assisted Zend to introduce Zend DBi as a drop-in replacement for MySQL on the IBM i platform. Zend approached us to say that they want to ensure there’s a way forward for IBM i users, and asked if we’d help them. We’re delighted to do so.

The result is Zend DBi. It is basically a renamed build of MySQL for IBM i. It’s a 100% compatible drop-in replacement. Everything works on Zend DBi just as it works on MySQL, with no need to rewrite applications, management scripts, or anything else. There is no difference in query …
