DAS provides the storage for DAS Enterprise Edition, which does not consume the storage of your database instance.
-
You can use the Audit, Security audit (old version), and SQL Explorer features only for data generated after you enable DAS Enterprise Edition and within the specified Data Storage Duration period.
-
Disabling DAS Enterprise Edition for a database instance also disables the SQL Explorer and Audit feature. This action does not affect your business operations, but it deletes all related data, including SQL Explorer data and analytical data. Before you disable DAS Enterprise Edition, export and save your data locally. For more information about data export, see Disable SQL Explorer and Audit.
-
After you enable or disable DAS Enterprise Edition for a database instance, you must wait about 3 minutes before performing the operation again.
