I love Wordpress.  Really there isn’t a better blogging platform on this platform.  It’s that good.  And I’ve been using it to self-host my blog for the past year or so.  For awhile, I hosted it using II6 on WHS v1.  That was a real pain as it took several days to find a URL rewriting solution that worked with IIS6.  The past few months I’ve been hosting it on my Windows 7-based media center.  Since that runs IIS7, URL rewriting was easier using the standard URL rewrite module.

A few days ago I decided to test out WHS “Vail”.  After installing it, I wanted to move my blog onto it so I downloaded the Microsoft Web Platform Installer.  It promptly let me know that it couldn’t find any products in my selected language.  Huh?  This is what drives people crazy about Windows software.

In our last installment we found our hero investigating the tracing changes found in Connector/Net 6.2.  This time we’ll take a closer look at the format of the trace data and how developers can use that information to write new and interesting trace listeners.

Understanding the plumbing

The first thing we need to understand is a little about how the trace messages are routed.  The main method we are interested in is TraceSource.TraceEvent.  Here is the signature.

public void TraceEvent(
    TraceEventType eventType,
    int id,
    string format,
    params Object[] args
)

All the other TraceSource methods like TraceInformation

For years, Connector/Net has been a key part of any MySQL & .NET developer’s toolbox.  Tracing is also a key part of a developer’s life and Connector/Net has always output trace messages. 

This first post is a review of .NET tracing systems and how we changed our trace output.  The second post will cover how developers can use the new tracing format to develop new applications.

Tracing in .NET 1.x

.NET shipped with a very simple tracing system.  You have a static class named Trace that has static methods such as Write and WriteLine.  An application can use code like the following to output a message to the trace log. 

Now that we have output our message, how do we direct it somewhere?  You do that with listeners.  There are a few standard listeners included in the framework

On the 24th of November I attended a talk given by one of of Sun's benchmark specialists , Dimitri Kravtchuk, at the Sun Solution Center of Paris.

The talk was simply called MySQL performance, and I was expecting, as many I suppose (the auditorium was packed !) tips and tricks on how to optimize a MySQL database. However I was quite positively surprised since the 3 hours session wasn't just a long list of tricks and “how to's” but was actually a journey through one and a half year of improvement of the InnoDB engine.

InnoDB could easily scale horizontally but not vertically. Horizontal scaling is the fact to put many small servers with each running a MySQL server (typically in a Master-Slave mode) where vertical scaling would be to put a unique MySQL server on a bigger server, expecting to get better performances. The latter is more and more needed given

We have an exciting webinar coming up tomorrow (12/15) on migrating from SQL Server to MySQL.  LiveTime Software is a leader in ITIL service management and help desk products.  They have started offering a free migration service and this webinar will go over everything from toolsets used to character sets. 

You can read more about it and register for this webinar here (http://mysql.com/news-and-events/web-seminars/display-466.html).  So I know you have an hour you can spare and when it comes time to renew that SQL Server license you’ll be glad you did.
