Developers… Please love your DBA – (Connection Strings)

I’ve been working alot with Resource Governor for SQL Server 2008 lately and one thing that has turned into quite a challenge is coming up with a good “Classifier Function“.

After much debate I decided that the best route to go is to use the “Application Name” primarily as my deciding factor as to what workload group a user’s connection will get placed in.

Through this process I found that a good portion of application connection strings DID NOT have this variable populated so most apps had the nice generic “.NET sqlClient Data Provider” description for their Program Name.

Needless to say an email was drafted and sent out requesting that all connection strings include the:

ApplicationName = <<Your App Name>>;

Now this is not just helpful for building Resource Governor classifier functions but if you’ve ever done some performance monitoring/tuning and used SQL Profiler think of the benefit of being able to possibly filter/investigate on a particular application name.

I’ll post more updates as to how developers can show their DBAs some love as I think of them.

Have a great weekend!!

  1. It looks like T-Mobile is among the first carriers to offer the update. The network operator has just confirmed OS 10.3.2 update will be available for BlackBerry Classic beginning June 17.

  2. The speaker snaps effortlessly into the back of the bumper case and you can remove it with similar ease. That said, the speaker never accidentally detached from the case when we were carrying it around in a bag or our pockets
