Without comprehensive testing, this has traditionally been a hard problem to identify and then resolve.
The Query Store feature maintains a history of query execution plans with their performance data, and quickly identifies queries that have gotten slower recently, allowing administrators or developers to force the use of an older, better plan if needed.
The Query Store is configured at the individual database level.
By: Allan Hirt on September 28, 2016 in SQL Server 2016, Windows Server 2012 R2, Windows Server 2016 If you’ve tried to install SQL Server 2016 on Windows Server 2012 R2, you may have run into an issue – KB2919355 may not be installed.
I did not look at the installation instructions (note: don’t ever do this …
updates are fussy and why I am writing this blog post) and plowed head installing the executable associated with KB2919355. Going back and looking at the instructions, buried in the last step is what I lovingly call an “oh by the way” – you have to install KB2919442 (also not shown as an optional update in WU) first. So to install SQL Server 2016 on Windows Server 2012 R2, here is the installation order for these fixes: If you are still having issues, you’ve got other problems going on that you will need to investigate. Note that if you are using Windows Server 2016, you will not encounter this issue. If you want to take advantage of Windows Server 2016 with SQL Server 2016, contact us – we can help get you up and running with features such as Storage Spaces Direct which I blogged about a few days ago and SQL Server just officially announced support for at Ignite.
In my case, I created a new VM with a fresh installation of Windows Server 2012 R2.
I also ran Windows Update to ensure it had everything Windows Server thought it required. I went to the KB article page for 2919355 (link is below) and clicked on the link for the Windows Server 2012 R2 files and downloaded all of them.
Microsoft offers a wide range of tools for Extract, Transform and Load (ETL), Analytics, and Reporting, from enterprise as well as self-service perspectives.
So effectively, Azure SQL DB gets the new toys first where they get tested out, and then the on-premises products benefit by getting features more quickly (in service packs or cumulative updates).
This rapid development cycle is great for development shops who are requesting the new features -- but where does it leave large enterprises who have to deal with testing cycles and regulation to upgrade versions?
Here we can see that it is possible to upgrade RC3 as its detected as an existing upgradable version of SQL Server for SQL 2016 GA.
