Simple MySQL Proxy Failover

I spent way too long figuring out code that would simply load balance based on, always go to one server, go to another server only when the first server is down., again running into the problem where the manual hasn’t been updated. I have made a Forge snippet of this code, but it does not hurt to post it here.

Minimal Logging Basics and SQL Server 2008 Enhancements

After spending a long time on a project for a client that does a huge amount of data movement using SELECT INTO, I posted a Connect item asking for an enhancement where a minimally-logged insert would be available from a SELECT doing an INSERT into an existing table. One day the item was updated with a comment: “This is targetted to be available in SQL Server 2008.” I wasn’t sure exactly what this meant until the last few days, when Sunil Agarwal posted a series of three posts describing the enhancements to minimal logging in SQL Server 2008 — including the ability to do a minimally logged insert via a SELECT, to an existing table!

3 Tips on Using dg4odbc on 64-bit Linux

I recently imported the contents of an Oracle 8i database into an 11g database. After following the instructions for a typical setupI set up a database link to a remote SQL Server database, and called it SQLSERVER.. It turned out that dg4odbc has “hard coded” the quotes and this will need to be changed in odbc.ini. I should have looked more closely at the installation instructions — yes, the example shows QuotedId=Yes.

Unintentional Googlewhack Leads to MySQL Bug Report

While doing a standard audit for a new client, I recommended a few changes to get better performance. Because I had several changes, I used the documentation and found that innodb_flush_log_at_trx_commit is a dynamic variable. I was surprised, because most operations dealing with file sizes and operations are not dynamic. So I searched for others who may have had the same error, and ended up getting an unintentional googlewhack.

Neighborhoods and Communities

Calling a group of people with common interests “community” is just as meaningless as saying I live in a “neighborhood”. There has to be a bond there. I am proud to be a part of the MySQL Community, which actually has forged bonds. If you are new to the MySQL community, feel free to come up and talk to me (or anyone, really) — during the conference, or otherwise. Even if you feel you have nothing to say, just say hello. And I must end with a disclaimer: I won last year’s “Community Advocate” award from MySQL, so I guess all in all, I’m still a community advocate.

New Oracle E-Business Suite Blogger

My name is Vasu Balla, and I’ve been with Pythian for about four months now. I have worked on Oracle E-Business Suite instances for over five years, and I’ve never had a moment where I felt bored. I am constantly challenged with new technologies and new issues, and my Pythian team’s clients continue to present interesting issues. Our team recently encountered an issue a client had had with Oracle Configurator for two years. They had followed up with Oracle Tech Support for over a year and had eventually learned just to live with the problem. When Pythian came in, we were shocked to learn the history of the problem. It turned out to be one of the most exciting problems we’ve resolved.

Distribution Cleanup job and xp_cmdshell

Recently I encountered a SQL Server 2005 Replication setup where an error message was appearing about every 5 minutes in the SQL Server error logs. The error message was coming from the failing distribution cleanup job. Examining the job history I was able to determine the real error message. The first step in debugging was to confirm if xp_cmdshell was enabled….

Is Summer Canceled in Ottawa This Year?

If you are a regular reader of this blog, you know that I was at the Hotsos Symposium 2008 this year. You might not know that I also had a chance to take few days off and spend 1+ week vacation in Texas after the symposium — enjoyed the sun and warm weather. My family liked that even more than I did. Unfortunately, when I was back home last weekend, I discovered pretty unpleasant view from my windows…
