You must create a private endpoint to connect Database Management to an Oracle Cloud Database.

The private endpoint is a representation of Database Management in the VCN in which the Oracle Cloud Database can be accessed, and acts as a VNIC with private IP addresses in a subnet of your choice. The private endpoint created in a VCN can be used to enable Database Management for the Oracle Cloud Databases available in the same VCN and it cannot be used across multiple VCNs. The private endpoint does not have to be on the same subnet as the Oracle Cloud Database, although it must be on a subnet that can communicate with the Oracle Cloud Database.

In Database Management, you can create the following types of private endpoints:

• Private endpoint for single instance Oracle Cloud Databases: You can create a maximum of five Database Management private endpoints in your tenancy (per region) to connect to single instance Oracle Cloud Databases in the Bare Metal and Virtual Machine DB systems. There's no restriction on the number of single instance databases for which you can enable Database Management using a single private endpoint. The private endpoint for single instance Oracle Cloud Databases has only one private IP address.
• Private endpoint for RAC Oracle Cloud Databases: You can create only one Database Management private endpoint in your tenancy (per region) to connect to RAC Oracle Cloud Databases in the Virtual Machine DB system and Exadata Cloud Infrastructure. One private endpoint for RAC Oracle Cloud Databases can support up to 15 Single Client Access Name (SCAN) listeners. In the case of Virtual Machine DB systems, a SCAN listener is equal to one RAC Virtual Machine DB system. In the case of Exadata Cloud Infrastructure, it's equal to one Exadata VM cluster, regardless of the number of individual RAC databases hosted on the Exadata VM cluster. The private endpoint for RAC Oracle Cloud Databases has two private IP addresses.

Note that you can create one private endpoint of each type in a VCN, which means that you can create one private endpoint for single instance databases and one for RAC databases. If you need more private endpoints than the default limit of five single instance private endpoints and one RAC private endpoint in a tenancy, you can request for an increase to the private endpoint limit. For information, see Could not provision Database Management private endpoint. Please retry operation or contact Oracle Support.

Here's a diagram that provides an overview of how a Database Management private endpoint communicates with the Oracle Cloud Database.

For information on private endpoints, see About Private Endpoints.

Before you create a Database Management private endpoint in the VCN, you must:

1. Sign in to the Oracle Cloud Infrastructure console.
2. Open the navigation menu, click Observability & Management. Under Database Management, click Administration.
3. On the left pane, click Private endpoints.
4. On the Private endpoints page, click Create private endpoint.
5. In the Create private endpoint panel:
   1. Name: Enter a name for the private endpoint.
   2. Description: Optionally, enter a description for the private endpoint.
   3. Choose compartment: Select the compartment in which you want the private endpoint to reside. By default, the compartment selected on the Private endpoints page is displayed, however, you can select another compartment in the drop-down list.
   4. Use this private endpoint for RAC databases: Select this check box if you want to create a Database Management private endpoint for RAC Oracle Cloud Databases in the Virtual Machine DB system or Exadata Cloud Infrastructure. The Database Management private endpoint for RAC Oracle Cloud Databases is a limited resource and you can create only one such private endpoint in your tenancy.
   5. Virtual cloud network: Select the VCN in which the Oracle Cloud Database can be accessed. By default, the compartment selected on the Private endpoints page is displayed, however, you can click Change compartment and select another compartment, if required.
   6. Subnet: Select a subnet within the selected VCN. Depending on whether the new Database Management private endpoint is for single instance or RAC Oracle Cloud Databases, it will take up two or three private IP addresses respectively, in the selected subnet. Note that the subnet can be in a different compartment than the VCN, however, it must have access to the database subnet in the VCN. By default, the compartment selected on the Private endpoints page is displayed, however, you can click Change compartment and select another compartment, if required.
   7. Network security group: Optionally, select an NSG added to the Bare Metal or Virtual Machine DB system or the Exadata VM cluster. You can also click + Another security group to select another NSG.
      Note
      
      The option to associate existing NSGs in the DB system or VM cluster with the Database Management private endpoint ensures that the private endpoint can access the database. Using the NSG you can add ingress and egress security rules to enable communication between the Database Management private endpoint and the Oracle Cloud Database. For information on NSGs, see Network Security Groups.
   8. Click Create private endpoint.
