We all want high performing applications and when you are in the cloud that is no different, if anything it is even more important. With this post I will discuss some areas where I have been “stung” by so you can learn from my mistakes when using Azure SQL Database. Then I will dedicate a section on what tools you can use to help with your performance tuning exercises.
A quick elementary post which is my entry to this months’ T-SQL Tuesday entry hosted by a good friend SQLDoubleG http://www.sqldoubleg.com/2017/07/03/tsql2sday-92-lessons-learned-the-hard-way/.
We are here to talk about mistakes we used to make. There is one mistake that I am going to discuss and is something that I used to do 10 years ago, obviously I do not do this anymore.
I have a SQL Server that is constantly producing “dump” files (with a MDMP File type), these are named SQLDumpxxxx (xxx = numerical value). They are located in the following directory: C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Log\ – sound familiar?
Have a look at this screen shot – it’s messy!
Thanks to Grant for hosting this month’s T-SQL Tuesday found (http://www.scarydba.com/2017/06/06/t-sql-tuesday-091-databases-devops/) where it is a chance to share our DevOps stories. I am not going into specifics of databases but I am going to write about it more generally.
