John Powell from eMapSite stopped by at the Whisper Suite in MySQL Users Conference earlier today to talk about his GlassFish issue. The possible workaround was suggested and then the discussion became interesting on how GlassFish is used for offshore monitoring of windfarms and process weather forecasting data. Hear all about it and watch a flashy demo of their product in this video:

NetBeans, GlassFish, and MySQL is their development stack with a "very positive experience"!

The second most frequent question people have asked me since MySQLConf started is “Why 5.4? What happened to 5.2 and 5.3?  Why not 5.5?”  I got an answer to this at lunch today from someone who was involved in the decision making process on this.  So here is the story as I understand it.

Why not 5.2?  IF you recall your ancient history, 5.2 was the original plan for post-5.1 features, before it was renamed to 6.0 for marketing reasons.  Because of some internal issues at Sun/MySQL and also to reduce confusion they did not want to reuse that same version number for the next product.  This makes a lot of sense to me, reusing the same version number for two different products could definitely cause some confusion.

Why not 6.0?  Short answer is that because of the reduced featureset, the new version didn’t warrant a whole new major version number.  I think this is correct, because if they …

MySQL just increased its enterprise attractiveness, but Oracle may not let it keep it.

My talk on libmysqld was yesterday, but I am not off the hook yet, as I still have a talk on Thursday on High Availability with MySQL, this time together with Robert Krzykawski of bWin, who will provide a real-world view on High Availability with MySQL. This is going to be a fun, as I think Robert has some interesting experiences when it comes to High Availability with MySQL running on a large website.

I went to Anthony Curtis talk on an …

Yesterday was the surprise announcement of MySQL 5.4 at the 2009 MySQL Conference and Expo. It was unfortunate that the supporting information was not that forthcoming on the MySQL website. I tried for several hours to try and download, but no mirrors were initially available. Today I see some information on the mysql.com home page and finally able to get the binary.

What I found most significant with this new major version release is a change in the binary distribution, as seen on the Download page.

MySQL 5.4 is only available on 3 platforms:

• Linux (AMD64 / Intel EM64T)
• Solaris 10 (SPARC, 64-bit)
• Solaris 10 (AMD64 / Intel EM64T, …
