6.3.6 Set '3625 (trace flag)' database flag for all Cloud SQL Server instances to 'on' (Automated)

Description

Best practices recommend setting 3625 (trace flag) database flag for Cloud SQL on SQL Server instance to on.

Remediation

From Console:

  1. Go to the Cloud SQL Instances page in the Google Cloud Console by visiting: https://console.cloud.google.com/sql/instances.
  2. Select the SQL Server instance for which you want to enable to database flag.
  3. Click Edit.
  4. Scroll down to the Flags section.
  5. To set a flag that is new to the instance, click Add item, choose the flag 3625 from the drop-down menu, and set its value to on.
  6. Click Save to save your changes.
  7. Confirm your changes under Flags on the Overview page.

From Command Line:

  1. Configure the 3625 database flag for every Cloud SQL on SQL Server database instance using the below command.
gcloud sql instances patch <instance_name> --database-flags="3625"=on
info

This command overwrites 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 uses the default value. For flags that do not take a value, specify the flag name followed by an equals sign ("=").
