Naturally (by default) SQL will consume all the memory available within its environment. There are times some applications require a minimum of memory allocated to the SQL instance before you can proceed with the application install. Below is how you can configure the minimum and maximum memory allocation your SQL instance can consume.
For starters, I am going to assume you understand how much memory (RAM) is available to your SQL server, and you have done the math behind any other SQL instances that may be within your SQL server…
In my case, I am going to ensure my application will always have a minimum of 12GB of memory, and a maximum of 14GB. The server itself has 16GB, and I will leave 2GB for the OS.
Launch your SQL Server Manager > right-click on the named instance > select Properties > select the Memory tab > define your settings here.
That is it!
