Have been meaning to post about the cluster setup I'm using for *functional* testing (not appropriate for performance testing or production environments).

The gist is that I'm using Parallels on OS X, running 4 nodes (1 management, 2 & 3 storage, 4 SQL) on 4 virtual machines. Each machine has between 128Mb and 256Mb of allocated RAM which isn't much for a cluster, but is as much as I can give from the 2Gb on the MacBook Pro. Each virtual machine has a version of MySQL 5.1.12 compiled from source. Actually, I built one VM with the compiled and installed source and then cloned that for the other 3 machines. The preferred flavor of Linux for these is Ubuntu server.

As I was setting up for a screenshot I walked through bringing …

I'll be at LCA 2007 in Sydney in January... Stewart and Colin are coming also, and quite possibly Brian. We're setting up a MySQL miniconf this time, and of course we would like to see some items from people who are not MySQL employees! See here:

This is a call for participation in the MySQL Miniconf which will be part of the linux.conf.au (LCA) 2007 conference in Sydney, Australia. The Miniconf will be run on Monday, January 15th, before the conference proper starts. This is the first conf of its type to be held in the Southern hemisphere and we are looking forward to participants from areas around Australia, New Zealand, South-East Asia, India and South America.

Any topic based around MySQL is allowed. Types of presentations that we're after, include:

MySQL MiniConf at linux.conf.au 2007
This implies I’m coming to linux.conf.au 2007 in Sydney next January. What’s more is that during the MiniConfs, we’ve got one for MySQL. Its on January 15th, and we’ve just put out the call for participation/papers. You have about eight (8) days left to submit a paper. So submit your tales of deployment, conference presentations, and I believe we’re even willing to accept “hand’s on” hacking sessions (ala what happened at MySQL Camp). Keep the wiki page handy, and submit goodies to mysql-miniconf[AT]mysql[dot]com.

The next version of CouchDbX comes with nice buttons and a cute interface. Enjoy the tease!

Some people who know I've used Gentoo asked me my thoughts on using it for MySQL servers. Here are my opinions and experiences using Gentoo, both for desktop systems and for servers.

Zmanda recovery manager for MySQL 1.1.2 is available from Zmanda downloads page. This release has been tested on Debian distribution and on MySQL server 4.0.24.

I want to acknowledge Thorsten Schifferdecker’s contribution to this release. He helped us by creating debian packages for earlier releases and provided good feedback on the product.

Lots of bugs have been fixed and this release has underwent more testing with different MySQL configurations.

Take a look at ZRM for MySQL wiki for changes, documentation, try it in your MySQL configuration and feel free to provide feedback on forums.

Today Pentaho released the first milestone of “Pentaho metadata” as a new core utility to make the life of BI professionals yet a little bit easier.

As you can see in the screenshot of the Pentaho metadata editor above, we offer a solution that bridges the gap between the worlds of the relational databases and business information. Here are a few of the key points that differentiate Pentaho metadata from the competition:

• Completely open
  • Released under an open source license (Mozilla Public License v1.0)
  • Persisting in the Common Warehouse Metamode, a recognised industry standard, potentially allowing for easier interoperability with 3rd party tools

I needed SSL connection feature for secure offsite replication. The prebuilt binaries do not include the SSL option, so I had to build MySQL from source with the SSL option....
