Just another day while doing performance tuning engagement, Senior DBA of the organization and I both noticed that one of the SP sp_readrequest is continuously listed as long running SP. Well, the good part was that it was not taking too much of the resources. The page read and write were pretty low and the SP was not blocking anything at all. Initially we decided to ignore this SP as there were quite a lots of other things which we needed to take care to get maximum performance of the server.
SQL SERVER – Troubleshooting: When Database Creation Takes Long Time
This might not be an issue which would be faced by SQL DBAs regularly because databases are generally already created. There might be few DBAs out there who take care of deployment as well. So, if you are having an issue with slow database creation, then you have found the right blog to try some troubleshooting.
SQL Server Performance Tuning Practical Workshop – Notes and Thoughts
In the month of January, I offered exclusive training to my newsletter subscribers. The training was extremely unique and was available for a limited time. Quite a lot of newsletter subscribers took advantage of this limited time offer of “SQL Server Performance Tuning Practical Workshop”.
SQL SERVER – TDE Effects on TempDB’s Slow Performance
I am a big supporter of the fact that testing and playing with new features should not be done on production environments. It can prove to be harmful, even after you tried to clean up the system. Sometimes we are not sure what the impact of our acts can lead to. In a recent consulting engagement, I figured this out the hard way. I was brought in for slow performance suddenly and we were not sure what was happening in the system. I love tough challenges and this was no different.
SQL SERVER – CLONEDATABASE: Generate Statistics and Schema Only Copy of the Database
I have been writing about how some of the interesting enhancements made with SQL Server 2016 SP1 have caught my attention. This one is a killer feature that can be of great value when you are trying to do testing. Having said that, I also want to call out that this feature has been added with SQL Server 2014 SP2 too. When you get into performance problems related to the query optimizer, then this capability will be of great advantage. In this blog post we will learn about Generate Statistics and Schema Only Copy of the Database.
SQL SERVER – Performance Analysis of Backup to Azure
It is second to human nature to compare when given options. When I wrote about the blog, SQL SERVER – Playing with Backups and Compression, I did compare some of the space savings one will achieve when working with backups and compression. Though the space savings were significant, one of the blog readers wanted to understand how this would be on time? Is it faster or slower to do the same. I went about taking the same script and I collected the time taken. Let us learn about Performance Analysis of Backup to Azure.
SQL SERVER 2016 – Creating Clustered ColumnStore with InMemory OLTP Tables
I have been writing a lot of my findings with SQL Server 2016 in the recent past. This is also being something I have been investing big time keeping my session at SQLPASS coming in the October timeframe. I will be talking on a number of capabilities and enhancements around SQL Server 2016 from a performance standpoint that it is critical for me to explore some. I invest considerable time in preparation for any session and every single year going to SQLPASS has been the highlight and most of the time it is about hard work to make sure everyone attending my session gets the best of content. Also, it is a great way for me to do due diligence and homework as I prepare with real world problem statement with possible alternatives and solutions as part of my session. Let us learn about Creating Clustered ColumnStore with InMemory OLTP Tables.
