Control: 6.3.3 Ensure 'user connections' database flag for Cloud SQL SQL Server instance is set as appropriate

Description

It is recommended to set user connections database flag for Cloud SQL SQL Server instance according organization-defined value.

The user connections option specifies the maximum number of simultaneous user connections that are allowed on an instance of SQL Server. The actual number of user connections allowed also depends on the version of SQL Server that you are using, and also the limits of your application or applications and hardware. SQL Server allows a maximum of 32,767 user connections.

Because user connections is a dynamic (self-configuring) option, SQL Server adjusts the maximum number of user connections automatically as needed, up to the maximum value allowable. For example, if only 10 users are logged in, 10 user connection objects are allocated. In most cases, you do not have to change the value for this option. The default is 0, which means that the maximum (32,767) user connections are allowed.

Remediation

This recommendation is applicable to SQL Server database instances.

From Console

  1. Login in to Cloud SQL Instances
  2. Select the SQL Server instance for which you want to enable to database flag.
  3. Under Configuration section
  4. Scroll down to the Database flags section. Click on Edit Configurations
  5. In the edit page, navigate to Flags and Parameters section
  6. To set a flag that has not been set on the instance before, click Add item, choose the flag user connections from the drop-down menu, and set its value to your organization recommended value
  7. Click Save to save your changes.
  8. Confirm your changes under Flags on the Overview page.

Note: Any changes to the database flag values, may require your instance to be restarted

From Command Line

  1. List all Cloud SQL database Instances
gcloud sql instances list
  1. Configure the required database flag for every Cloud SQL SQL Server database instance using the below command.
gcloud sql instances patch INSTANCE_NAME --database-flags "user connections=[0-32,767]"

Note: This command will overwrite all database flags previously set. To keep those and add new ones, include the values for all flags you want set on the instance; any flag not specifically included is set to its default value. For flags that do not take a value, specify the flag name followed by an equals sign ("=").
