Configure Access Control Lists for an Existing Autonomous Database Instance

You can control and restrict access to your Autonomous Database by specifying network access control lists (ACLs). On an existing Autonomous Database instance with a public endpoint you can add, change, or remove ACLs.

Configure ACLs, or add, remove, or update existing ACLs for an Autonomous Database instance as follows:

  1. On the Details page, from the More Actions drop-down list, select Update Network Access.
  2. In the dialog, under Access Type, Allows secure access from everywhere, specify the access control rules by selecting an IP notation type and values:
    • IP Address:

      In Values field enter values for the IP Address. An IP address specified in a network ACL entry is the public IP address of the client that is visible on the public internet that you want to grant access. For example, for an Oracle Cloud Infrastructure VM, this is the IP address shown in the Public IP field on the Oracle Cloud Infrastructure console for that VM.

    • CIDR Block:

      In Values field enter values for the CIDR Block. The CIDR block specified is the public CIDR block of the clients that are visible on the public internet that you want to grant access.

    • Virtual Cloud Network:
      • In Virtual Cloud Network field select the VCN that you want to grant access from. If you do not have the privileges to see the VCNs in your tenancy this list is empty. In this case use the selection Virtual Cloud Network (OCID) to specify the OCID of the VCN.
      • Optionally, in the IP Addresses or CIDRs field enter private IP addresses or private CIDR blocks as a comma separated list to whitelist specific clients in the VCN.
    • Virtual Cloud Network (OCID):
      • In the Values field enter the OCID of the VCN you want to grant access from.
      • Optionally, in the IP Addresses or CIDRs field enter private IP addresses or private CIDR blocks as a comma separated list to whitelist specific clients in the VCN.
  3. Click + Another Entry to add a new value to the access control list.
  4. Click x to remove an entry.
    You can also clear the value in the IP Addresses or CIDR Blocks field to remove an entry.
  5. Click Update.

If the Lifecycle State is Available when you click Update 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.
