PerconaLive Amsterdam 2016 - Talks and shows

With Oracle Open World behind us, we are now getting ready for the next big event, i.e. the European edition of PerconaLive. I am going to be a presenter three times:

  • MySQL operations in Docker is a three-hour tutorial, and it will be an expansion of the talk by the same title presented at OOW. Attendees who want to play along can do it, by coming prepared with Docker 1.11 or later and the following images already pulled (images with [+] are mandatory, while [-] are optional):

The fastest MySQL Sandbox setup ever!

MySQL-Sandbox 3.1.11 introduces a new utility, different from anything I have put before in the MySQL Sandbox toolkit.

make_sandbox_from_url downloads a tiny MySQL tarball from a repository and install it straight away.

As of today, the following packages are available

Major release versions package size
(what you download)
expanded size
(storage used)
original size
(not included)
5.0 5.0.96 20M 44M 371M

MySQL Sandboxes in Docker

Overview

When I got interested in Docker, I started playing idly with the idea of integrating containers and MySQL Sandbox. My first experiments were not encouraging. Using a container the same way I would use a regular server produced horrible results. I started by creating a Debian or CentOS container, installing MySQL Sandbox, and then importing an expanded tarball into the container. What happens is that tarballs of recent MySQL versions expand to roughly 2 GB of binaries. When you try to put that into a container you get a bloated file system. If you want to expand more than one tarball, you get an enormous unusable blob that is contrary to what containers should be used for. There is, of course, the possibility of using volumes, which would avoid the problem of making the container …

MySQL Sandbox at the OTN MySQL Developers day in Paris, March 21st

On March 21st I will be in Paris, to attend the OTN MySQL Developers Day. Oracle is organizing these events all over the world, and although the majority are in the US, some of them are touching the good old European continent. Previous events were an all-Oracle show. Recently, the MySQL Community team has been asking for cooperation from the community, and in such capacity I am also presenting at the event, on the topic of testing early releases of MySQL in a sandbox. Of course, this is one of my favorite topics, but it is quite appropriate in this period, when Oracle has released a whole lot of preview features in its MySQL Labs. Which is another favorite topic of mine, since I was the one who insisted for having the Labs when I was working in the …

MySQL 5.1.47 and 5.0.91 released - Two strong reasons to upgrade
MySQL has released security updates for MySQL 5.1.47 and 5.0.91. The most important changes in these releases are fixes of three security bugs. One of them is a problem that had been lurking in the code for many years, and it was found by chance when one of our developers, testing something unrelated, stumbled upon one of the vulnerabilities. Later on, when analyzing the bug, the developers found one more issue, and they fixed it as well.

MySQL 5.1.47

In addition to the security update, MySQL 5.1.47 is also very important for an additional reason. The InnoDB plugin that ships with this version has been updated to 1.0.8, which is …

Further Thoughts on MySQL Upgrades

I have been upgrading more MySQL database instances recently and have found a few more potential gotchas, which if you are not careful, can potentially be rather nasty. These are not documented explicitly by MySQL, so it may be handy for you to know if you have not come across this type of thing before.

Most of the issues are those related to upgrading MySQL instances which are replicated, either the master servers or the slaves. Some seem specific to the rpm packages I am using (MySQL enterprise or MySQL advanced rpms), though others are not.

Take care upgrading a 5.0 master when you have 5.1 slaves

It is not a good idea to run a mixed major version of mysql in a replicated environment so why would I be doing this? If you work in a replicated environment and have several slaves then it is recommended that you upgrade the slaves first. I work with quite a few slaves so the process of upgrading them all takes longer …

Thoughts on MySQL 5.1 and later

It’s been a while since I’ve posted anything new. In the meantime I’ve been pretty busy. Working on production systems often means that you are not running bleading edge. That’s fine but sometimes you need to look at doing the upgrade and to do that you have to do quite a few checks to see how well newer versions of the software you use will work.

I’ve been in that situation with MySQL. I have quite a few boxes most of which are 5.0 and have been working fine. MySQL-5.1 has been GA now for some time, and I have started to look at it as support for 5.0 is about to end.  I’ve already found quite a few 5.1 bugs, good enough to crash the server, but again that’s to be expected. Heavy loads and odd usage of the server means that MySQL can never be able to test all things.  Replication problems caused a few issues with the first versions of 5.1 but they all seem to have been ironed out now.  The other …
