This is the second article in a series about internals and performance of concurrent managers. In this post, we’ll take a look at three important settings that affect the performance of the concurrent managers: number of processes, “sleep seconds”, and “cache size”. This article might be a bit on the theoretical side, but it should provide a good understanding of how these settings actually affect the behavior and performance of concurrent managers.
This is the first article in a series about performance of concurrent processing. We’ll take a closer look at the internals of concurrent managers, the settings that affect their performance and the ways of diagnosing performance and configuration issues. Today we’ll start with an overview of the internal workflow of a concurrent manager process. Enjoy the reading!
If you’re like me and are a DBA in the UK with a penchant for MySQL or Oracle, you’ll know we have a smörgåsbord of conferences here next week. We’ve been waiting, and like buses two have come at once. We have the UK Oracle User Group Conference 2012, in Birmingham on 3rd – 5th December 2012, and the Percona Live London MySQL Conference running on 3rd – 4th December. Pythian will be speaking at both events.
A mere 5,018 minutes until the festivities start at the 2012 version of the UKOUG User Group Conference. The show is intense and hugely educational with some of the world’s finest in attendance and presenting. For us Pythian’ites the trek terminates on Wednesday evening with British football’s Manchester United. Keep a close eye out for RACAttack above the vendor forum. Pythian’s own Alex Gorbachev and others will help you attack the RAC. Not to be missed.
Andrew Moore and Ben Mildren return from Ottawa to Bristol to London all in the name of MySQL
For those of you attending UKOUG today, there is a healthy dose of Pythian presentations on tap this afternoon. Actually, you can do it wall to wall 2:30pm to 6:30pm if you like.
Welcome to Log Buffer, the weekly round up of news and happenings in the database world.
OpenSQLCamp 2009 is happening “in parallel to the Free and Open Source Conference 2009 (FrOSCon) on Saturday 22nd and Sunday 23rd August in St. Augustin, Germany …. close to Bonn and Cologne.” I plan on being at FrOSCon and OpenSQLCamp. Where I go before and after that is up to *you*. Yes, that is right, perhaps I will visit a user group, such as France’s MySQL User Group. Or perhaps your company needs the type of services Pythian can offer — we can do the “traditional consulting” model where we look over your systems for performance tuning and security gains, or fix problems in an emergency
OpenSQL Camp will take place Saturday 22nd and Sunday 23rd of August, in St. Augustin, Germany, so it could do for a nice August getaway to Germany. It’s not really the biggest of cities, but then again, that is part of the charm, going to some small city and learning more about databases.
In case you do happen to be curious, feel free to check out the list of proposed sessions, although it is not complete, it does give a overview of what to expect.
Paul Vallée, Pythian’s founder and Executive Chairman really opened our eyes. Paul talks about Oracle’s 11G features with the same enthusiasm he has for MySQL’s federated architecture, or for SQL Server’s peer-to-peer replication technology. You could hardly find anybody who presents his visionary views of the new technology trends like cloud computing, virtualization, or server consolidation with such a deep understanding of the topics. Here is your opportunity to confer with Paul Vallée on Thursday, June 4, 2009 12:00 PM–1:00 PM CEST (11AM–12:00 PM GMT) in a free webinar, Database Platform Migration.
