A few weeks ago we announced the Oracle VM Template for MySQL Enterprise Edition, which helps eliminate manual configuration efforts and risks by providing a pre-installed, pre-configured and certified software stack including Oracle VM Server for x86, Oracle Linux with the Unbreakable Enterprise Kernel and MySQL Enterprise Edition.

On Tuesday August 23rd at 10.00 am PT, Oracle will be hosting an Oracle virtualization launch event.

If you’re based in the SF bay area, you’re …

Boston, Mass., August 15, 2011 – ScaleBase, Inc. today announced the general availability of ScaleBase 1.0 for unlimited scalability of MySQL databases. ScaleBase 1.0 delivers MySQL performance and high availability, without the need to change a single line of application code. Users of MySQL can download and easily deploy the software by visiting http://www.scalebase.com/solution/download/.

ScaleBase utilizes two techniques for scaling: read-write splitting and transparent sharding (a technique for massively scaling-out relational database). The software enables MySQL to scale transparently, without forcing developers to change a …

Codebits is an annual 3-day conference about software and, well, code. It's organized by SAPO and this year's edition is to be held on November 10 thru 12 at the Pavilhão Atlântico, Sala Tejo in Lisbon, Portugal.

I've never attended SAPO Codebits before, but I heard good things about it from Datacharmer Giuseppe Maxia. The interesting thing about the way this conference is organized is that all proposals are available to the public, which can also vote for the proposals. This year's proposals are looking very interesting already, with high quality proposals from …

For those of you in around Sao Paulo this week, Aiton Lastori send me the following:

Next week we will host a MySQL Happy Hour at Oracle's Sao Paulo office.
We are exited because there are room for 100 people and over 500
subscribed! Oracle marketin provided the money for the free beer and Ana, our lead dev in Brazil, and is doing an amazing job organizing
everything. I've created a group in meetup.com http://www.meetup.com/MySQL-BR/.

I am very glad that you are trying to maximize the developers inform me in particular is a very big help.

Thank you!

Installing Nginx With PHP5 (And PHP-FPM) And MySQL Support On CentOS 6.0

Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on a CentOS 6.0 server with PHP5 support (through PHP-FPM) and MySQL support.

Speaking of conferences, in general, and OpenSQLCamps in particular, there is one a week from now, and I will be speaking! It is organized as a single room track at Froscon, Germany, by Felix Schupp (Blackray/Softmethod) and Volker Oboda (Primebase). The content is mostly a collection of database related talks originally submitted via the main Froscon call for papers. (In other words, unlike many previous camps, the schedule is all set.)

I'm a little excited about this one, because for the first time in my career as speaker I will be giving the keynote. The title of my talk is

How I learned to use SQL and how I learned not to use it

I’ll be presenting at Oracle Open World on the causes of downtime in MySQL, and how to prevent it. This is a research-based session that presents an easy-to-digest post-mortem of hundreds of emergency issues filed by Percona customers. The real causes and types of downtime surprised me quite a bit, and the preventions run counter to a lot of conventional wisdom. I’ll just give a preview by saying that you should consider it a top priority to monitor how full your disks are! On the other hand, despite the fact that every monitoring tool in existence shows the binary log cache hit rate, not a single emergency in Percona history has ever been attributed to that.

The agenda at OOW is mind-bogglingly huge (see Dave Stokes’s blog post, so here are the full …

A previous article on this blog described Tungsten parallel replication using on-disk queues.  On-disk queues are now more or less finished, and I just closed the covering issue for the feature.  The work is bug fixing and performance testing from here on out.  Speaking of performance, that looks fairly good.   A recent on-site test using production workloads showed 3.3X improvement over native MySQL replication while holding resources like memory down to much more reasonable levels than in-memory queues.  We have further optimizations on the way, so this should improve.

Now that parallel replication is working a lot better, what is it good for?  Here is a good start:  assuming your …
