SQL Computing Size

Posted February 1, 2020 770 views

Hello, I have resized my droplet to have 2gb of ram as opposed to 1gb. My site keeps going offline because the SQL server is limited with computing size. How do I increase how much memory the SQL database can use on the droplet or would it be best to migrate the sql database to a managed database.

Hi shehethey,

SQL Server will take up all the ram assigned to it,whether it use or not.If you have sufficient money,it’s better to buy managed database.

I have met resolve page allocation failures due to insufficient memory when sufficient memory is available.In this condition,If you get the error message,

Disallowing page allocations for database '*\<databaseName>*' due to insufficient memory in the resource pool '*\<resourcePoolName>*'. 

in the error log when the available physical memory is sufficient to allocate the page, it may be due to a disabled Resource Governor. When the Resource Governor is disabled MEMORYBROKER_FOR_RESERVEinduces artificial memory pressure.
To resolve this you need to enable the Resource Governor.To resolve this,maybe Microsoft’s docs can help you.Go to see this page

If this cannot help you,please commit a new work-ticket for DO team’s help.

Have a nice day.


Mysql memory usage is limited by the mysql config.

MySQLTuner: is a good tool which will help you to understand mysql resource usage and even limit as you need.

While you could limit mysql resource usage with mysql config changes, that may not guarantee that your application work well with mysql resource constrains you to implement.

So along with limiting mysql resource usage, you may have to use an additional support solution like a cache(Eg: Memcached) to reduce mysql queries which will help to reduce mysql resource usage as well.
