Set Access Control List for an Autonomous Database
An Access Control List (ACL) provides additional protection to your Autonomous Database by allowing only the client with specific IP addresses to connect to the database. You can add IP addresses individually, or in CIDR blocks. Enabling an ACL with an empty list of IP addresses makes the database inaccessible.
If the Lifecycle State is Available when you click Save the Lifecycle State changes to Updating until the ACL is set. The database is still up and accessible, there is no downtime. When the update is complete the Lifecycle State returns to Available and the network ACLs from the access control list are in effect.
