MySQL Sandbox at the OTN MySQL Developers day in Paris, March 21st
+4 Vote Up -0Vote Down
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  [Read more...]

MySQL 5.1.47 and 5.0.91 released - Two strong reasons to upgrade
Employee +7 Vote Up -0Vote Down
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,

Further Thoughts on MySQL Upgrades
+2 Vote Up -0Vote Down

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

Thoughts on MySQL 5.1 and later
+3 Vote Up -0Vote Down

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

FULLTEXT and Asian Languages with MySQL 5.0
Employee +1 Vote Up -0Vote Down

I have seen a few people now ask about using MySQL's FULLTEXT indexing with asian languages such as Chinese, Japanese and Korean (herein referred to as CJK.), however, there doesn't seem to be a good centralised article that covers it.

The information is out there, I just don't think it has been well presented yet.

As I have recently done a bunch of research on this topic for a customer, I figured it might be a good opportunity to make my debut in the MySQL blogosphere.

So here we go...

I'll open by saying that attempting to use FULLTEXT with CJK text in MySQL 5.0 will be unsuccessful.

From the CJK FAQ in the MySQL manual:

"For FULLTEXT searches, we need to know where words begin and end. With Western languages, this is rarely a problem because most (if not all) of these use an easy-to-identify word boundary

Quality of 5.1 GA release
+0 Vote Up -0Vote Down

With all due respect to Monty (and I mean that — much respect is due), I have some serious issues with his portrayal of the 5.1 release.  I hate to make my first entry on Planet MySQL about a controversy, but he encouraged people to blog about their experience with 5.1, so that’s what I’ll do here.

Overall Quality

As a long time user, I am very confident that the quality of 5.1 GA far exceeds that of the initial 5.0 GA release (5.0.15).  In fact, I would go further and suggest that the MySQL organization has if anything been too conservative about declaring 5.1 GA.

It’s obviously true that there are still many bugs open.  However no software is bug free, especially not those with codebase as large as MySQL.  So the question is not if they are bug free,
