How to contribute in openSUSE Build Service

I promised that I’ll write a post about how you can contribute. There are several ways how to contribute to MySQL, but most of it means modifying packages. And as everything in openSUSE is built using openSUSE Build service, first post will be actually pretty general obs and osc howto. In the next posts, I’ll go deeper into specific details of MySQL packaging.

Find the package

If you want to play with any package in openSUSE Build Service, you need to have a Novell login and preferably the osc command line client for obs. You can do most of the stuff from web as well, but this way is more comfortable So let’s say that we want to play with MariaDB. First we have to find package we want to update. This can be easily done on the web. Just take a look at packages at server:database repository. mariadb is …

Benchmarking Galera replication overhead

When I mention Galera replication as in my previous post on this topic, the most popular question is how does it affect performance.

Of course you may expect performance overhead, as in case with Galera replication we add some network roundtrip and certification process. How big is it ? In this post I am trying to present some data from my benchmarks.

For tests I use tpcc-mysql, datasize 600W (~60GB) with buffer pool 52GB. Workload is run under 48 user connections.

Free webinar on preventing MySQL downtime

I’ll be presenting a free one-hour webinar on preventing downtime in production MySQL servers, in conjunction with the ODTUG. It is scheduled on Thursday, November 10, 2011 3:00 PM – 4:00 PM EST, and you can register for free.

Here’s an abstract of what you’ll learn:

Everyone wants to prevent database downtime by being proactive, but how effective are the common measures such as inspecting logs and analyzing SQL? To be truly proactive, one must prevent problems, which requires studying and understanding the reasons for downtime. We have analyzed a selection of emergency issues that we have solved, to better understand what types of problems really occur in production environments. The results are somewhat surprising, and will be detailed in this talk. Most incidents we found were not MySQL-specific and will be familiar to Oracle DBAs as well as …

Dennis Ritchie, the creator of C, dies at 70..

When I first got in touch with C it was in the early 1980's. I was a sysadmin at a Swedish telco operator (then THE Swedish Telco operator, Televerket, nowadays called Telia) for a system used for software development for a PABX system called A345 in Sweden, better known as Meridian in the rest of the world (co-developed by Televrket and Nortel). The Meridian system was the biggest of the non-custom built PABXes in those days. The language used to program it was called SL-1 (Switching Language 1) and the development system, like editors (vi / ined), compilers etc was running on a Unix system.

This sure was one of the earliest commercial uses for Unix, the Unix variant was version 6 and was not a BSD or anything like that, this was way before BSD really. Rather, the system was built by Interactive Systems which was the first commercial Unix vendor. This was version Interactive 2.5, based on Unix version 6, mind you. sh and csh only, no …

iPad Ready Dashboard & Wayback Machine

We are pleased to announce the release of MONyog 4.7 GA. Below is a brief on new features:

Dashboard

The world is moving towards tablets (I agree iPad in the title is a misnomer) and most of them don’t support Adobe Flash. As you know MONyog dashboard charts were on Flash and did not work on tablets. With this release we have switched to HTML5 charts. Not only do they work on all Smartphones and Tablets, they are faster than Flash charts. Hence, desktop users also gain from this release.

Flash charts used elsewhere in MONyog are also changed to slick HTML5 charts.

Embedded in this post are screen-shots with relevant section zoomed-in on an iPad.

Call for Papers for Collaborate ends tomorrow!

The call for papers for Collaborate ends tomorrow, Friday October 14th.  Collaborate is Sunday, April 22nd through Thursday April 26th at the Mandalay Bay Convention Center in Las Vegas.  This year the folks scheduling the MySQL Conference and Expo have smartly chosen not to conflict, and in fact they are 2 weeks apart.

Collaborate is the largest independent (not put on by Oracle) conference for users of Oracle software.  This year we are having a one-day MySQL track at Collaborate, so that speakers and attendees can focus and optimize their time spent at the conference.

This is a great chance to give a talk to operations folks about running MySQL.  The audience is mixed, with some beginners and some intermediate folks.  We expect over 100 attendees to attend …
