This Thursday (February 19th, 14:00 UTC), MC Brown & Trond Norbye will give a MySQL University session on Developing MySQL on Solaris. MC works on the MySQL Documentation Team and has been involved with quite a few Solaris things, for example porting MySQL to openSolaris. Trond has been involved with many things, including openSolaris, as you can see from his blog.

Yesterday Sun introduced Glassfish Portfolio. Its a new stack of open source middleware products including Glassfish Enterprise Server, Glassfish ESB, Glassfish Web Space Server, and the new Glassfish Web Stack, which includes support for projects such as Tomcat, Memcached, Apache, PHP, Ruby and Python and a copy of MySQL Community.

It’s a pretty complete infrastructure stack. What it is not, however, is an integrated LAMP stack, despite Sun’s reference to it as such not once but twice on its press announcement.

Glassfish Portfolio runs on Linux of course, as well as Solaris, but it does not contain Linux (integrated or otherwise) or Linux services (although that is available …

I’m speaking at the User Conference this year, with a half-day tutorial and three further sessions. The running theme is performance, both in terms of the performance of your queries, and in terms of scaling up.

Scale Up, Scale Out, and High Availability: Solutions and Combinations

This is the big tutorial. It’s difficult to resolve what I’ll be talking about into a few sentences, but think about all of the different technologies available here - replication, partitions, sharding, DRBD, memcached - I’ll be talking about all of them, and more importantly combinations of the different solutions and where the potential performance gains and pitfalls are. I’ll also be using the opportunity to demonstrate some of the more obscure combinations that you can use to provide the environment you need.

DTrace has been something that I’ve been trying to get into the MySQL server for more than a year now.

After a combination of my own patches and working with Mikael Ronstrom and Alexey Kopytov we finally have a suite of probes in MySQL 6.0.8. Better still, after a short hiatus while I was busy working on a million-and-one other things, the documentation for those probes is now available: Tracing mysqld with DTrace.

The documentation is comparatively light and deep all at the same time. It’s lightweight from the perspective that I’ve added very little detail on the mechanics of DTrace itself, since there is no need to replicate the excellent guides that Sun already provide on the topic. At the same time, I’ve tried to provide at least one (and sometimes two) D script examples for each of the groups of probes in the 6.0.8 release.

One year after Sun acquired MySQL we see the positive results of this acquisition. Things are going very well in terms of collaboration, the teams are getting closer together and share the experience and the knowledge. If you want to know how the teamwork is seen from the Sun Cluster engineers, Thorsten Frueauf and myself, you should read this.

It was interesting for us to see that this interview was well observed by MySQL customers and community members. Although the interviews were not technical, they lead to technical questions. You can get more information here.

So if you are keen to see what the MySQL community wants to know about Sun Cluster, read the blog entry about MySQL and Sun Cluster.

A while ago we published an interview with Detlef Ulherr and Thorsten Früauf about Solaris Cluster / OpenHA Cluster on the MySQL Developer Zone.

We received a number of followup questions from our readers, requesting more technical background information. For example, Mark Callaghan was wondering about the following:

• How is failure detection done?
• How is promotion of a slave to the master done after failure detection?
• How are other slaves failed to the new master?

I asked Detlef to elaborate some more on the technical details of this solution. Here's his very exhaustive reply, thank you very much, Detlef!

I would also like to point out that he'll be …

Wikimedia Foundation is expanding Wikipedia to multimedia with Sun Open Storage Solution and MySQL Database:

Wikipedia receives between 25,000 and 60,000 page requests per second, depending on the time of day. Wikimedia needed to update its infrastructure to handle this huge volume of traffic and ensure that its systems were reliable, highly available, and easily scalable. It also wanted to expand its upload file limit from 20 MB to 100 MB to accommodate rich media (audio and video) content, but before it could do that it needed to expand its storage capacity.
