Alrighty, my mistake. In the setup of the mirror infrastructure, I stuffed up the server alias logic so that some yum and apt-get requests will be failing at the moment (specifically on the us mirrors). The uk mirror should be ok. Either temporarily override your config for the uk mirror, or wait a few hours as things gets sorted on those systems. Sorry!

Update: all fixed now - and it seems the mirror people are smarter than I anyway

We’ll get some testing and monitoring in place for this kind of thing, it’s obviously very tricky to spot such problems otherwise.

Description

MySQL Replication is powerful technology, but many things can trip you up. Sometimes the slaves get out of sync with the master, or dump errors into their logfiles. Sometimes replication just can’t keep up. In this presentation will explain how to verify with checksums, avoid traps in your code, monitor, and even help you improve the performance of your replication setup.

Abstract

There are a few big gotchas with MySQL’s statement based replication. Non-deterministic functions can cause the slave to get out of sync, mixing innodb and MyISAM tables, to name just a few. What you need to do …

This past Tuesday I was doing more than just voting.  I was giving a live webinar on using MySQL with the Entity Framework.  We had a terrific time (demo machine crash included!) and had a great turnout.  I have been informed that we set records for most number of registrations and attendees.  I’m truly honored and hope that at least some of you got something out of it.

I’ve had a lot of people ask me for the materials from the session so I’ve made them available from my personal server.  You can get the slides, sample projects, and db script here.  The webinar was also recorded and will appear on this page eventually.

Thanks again to all who attended.  I’m hoping to give an expanded version of this session at our users conference …

When you write a blog post and tag it with something you know will allow it to be aggregated into PlanetMySQL (or any other technical aggregation service), ask yourself one thing:

If I was a technical person interested in MySQL, would I want to read what I just wrote?

Description

Drupal is an open-source CMS that has a huge user base and community. I recently managed the MySQL side of the equation for a Drupal-based website of a large television brand. There are some documents out there for high performance MySQL with Drupal, I found them lacking. So I did extensive benchmarking, and profiling of queries, to find the best overall setup.

Session type: 45 minute conference session

Topics: Business and Case Studies

Abstract

Drupal is the open-source CMS du-jour. It has become very popular very quickly, but performance isn’t …

Description

MySQL has a number of great features for managing archival data, and very large tables. We look at the MERGE storage engine first. Then we look at views which can hide many tables behind the scenes. And lastly we look at partitioned tables.

Session type: 45 minute conference session

Topics: Data Warehousing and Business Intelligence

Abstract

MySQL has some very powerful features for large databases now available in 5.1.

We’ll look at the MERGE storage engine first. Then we’ll take a look at views, and the strengths and weaknesses …

So, a while back, not sure when, I was listening to the P3 Podcast and Paul mentioned his dislike for Wordpress.  He said he wished there was a simple blogging application.  I am probably misquoting him horribly.  It was an idea that I had been tinkering with.  So, I started on Wordcraft in my spare time.  Like super spare time.  That time between the kids going to bed and me falling  asleep.  So, it took a while to get it to a usable state.

Up until now, I have used Wordpress.com for my blogging.  It works quite well.  You can get started quite quickly and it does what most people need.  My wife uses Blogger for our family blog.  It is, IMO, not as nice as Wordpress.com in some ways.  But, it does allow you to edit your styles (for free) and such which is nice.

So, why would I want to reinvent the …

A couple of weeks ago I was at the MySQL European Customer Conference in London, where I was presenting my talk on deploying MySQL on Solaris best practices. You can download a copy of the presentation here: MySQL on Solaris Best Practices.

I cover both choosing the best release version, using tricks like mtmalloc (the threaded malloc library) before moving on to UFS and ZFS tricks, using DTrace and MySQL Cluster and Sun Cluster.
