sp_configure: Limit SQL Server memory usage

Use the sp_configure system stored procedure with the max server memory option to limit the amount of memory in the buffer pool used by an instance of SQL Server or MSDE. This will prevent SQL Server from using more than the specified amount of memory, thus leaving remaining memory available to start other applications quickly. You cannot set max server memory to a value less than 4 MB. 16 MB or more is recommended especially if you are using replication. max server memory is an advanced option. You need to enable advanced options before you can use it.

Run the following SQL statements to limit the amount of server memory used to 64 MB:

 

Enable advanced options:

USE master
EXEC sp_configure 'show advanced options', 1
RECONFIGURE WITH OVERRIDE

 

Set the maximum amount of memory to 64 MB:

USE master
EXEC sp_configure 'max server memory (MB)', 64
RECONFIGURE WITH OVERRIDE

 

Display the newly set configuration:

USE master
EXEC sp_configure 'max server memory (MB)'

 

Set ‘show advanced options’ back to default:

USE master
EXEC sp_configure 'show advanced options', 0
RECONFIGURE WITH OVERRIDE
