Which are the three pre requisites to configure a private endpoint with autonomous databases?

Before you create a private endpoint in Data Catalog, you must have the following details:

• The name of the Virtual Cloud Network (VCN) used to access your data source.
• The name of the subnet in the VCN.
• The list of DNS zones used to resolve the FQDNs or private IPs of the data sources that you want to harvest.

  Important

  If the data sources in your private network are accessed with FQDNs and private IPs, you only need the list of all the FQDNs when you create the private endpoint.

  If all the data sources in your private network are accessed with private IPs, then while creating a private endpoint you must specify at least one resolvable FQDN or DNS.

  For private autonomous databases, use the FQDN of the database as the DNS zone. For custom data sources running on Oracle Cloud Infrastructure compute Virtual Machines (VMs), you can specify the FQDN of the VM, or the domain name of the subnet in which the VM is provisioned, or the domain name of the VCN.

Here's how you create a private endpoint:

1. Open the navigation menu and click Analytics & AI. Under Data Lake, click Data Catalog.
2. From the Data Catalog service page, click Private Endpoints.
3. Click Create Private Endpoint.
4. Select the compartment where you want to create the private endpoint. You can create the private endpoint in a different compartment than the compartment where your data catalog is created.
5. Enter a name to identify the private endpoint.
6. Select the VCN that is created to provide private access to your data source.
7. Select the Subnet that has the private endpoint to access your data source.
8. Enter the DNS zones to resolve. The DNS zone can be a DNS domain name or a FQDN. You can enter up to 30 DNS zones.

   Example: Consider a database with FQDN dcat.dbsubnet.dbvcn.oraclevcn.com installed on a machine. The permitted domain name entries can be: dbvcn.oraclevcn.com (VCN DNS), dbsubnet.dbvcn.oraclevcn.com (subnet DNS), or dcat.dbsubnet.dbvcn.com (FQDN). The private IP of the machine can not be specified.

   Important

   If the data sources in your private network are accessed with FQDNs and private IPs, you only need to enter the list of all the FQDNs.

   If all the data sources in your private network are accessed with private IPs, then enter at least one resolvable FQDN.

9. (Optional) Add tags to identify this private endpoint resource.
10. Click Create.

All private endpoints created in Data Catalog are listed in the Private Endpoints page. To view details for a specific private endpoint, click the private endpoint name. The private endpoint details page displays. Alternatively, click the Actions icon for the private endpoint and select View Details.

From the Private Endpoints list, you can also edit, move, or delete a private endpoint.

A private endpoint can be in one of the following statuses:

Here's how you attach a private endpoint to a data catalog.

1. From the Data Catalogs list in the Console, click the Actions menu (
   
   ) for the data catalog where you want to attach a private endpoint and then select Attach Private Endpoint.
2. From the Attach Private Endpoint dialog, select the private endpoint that you want to attach to the data catalog. If the private endpoint was created in a different compartment than the data catalog, then you have to change the compartment before selecting the private endpoint.
3. Click Attach.

A notification displays indicating that the private endpoint is being attached to the data catalog. A notification is also displayed after the private endpoint is attached successfully to the data catalog.

When you create a data asset in the data catalog service console, you can specify that you want to use the private endpoint you have created and attached to the data catalog.

Caution

Do not specify that you want to use a private endpoint without creating and attaching a private endpoint to the data catalog. If you do, you receive an error while creating the data asset.

Here's how you edit the private endpoint name and DNS zones:

1. From the Data Catalog page in the Console, click Private Endpoints.
2. From the Private Endpoints list, click the Actions menu (
   ) for the private endpoint you want to edit and select Edit. Alternatively, you can click the name of the private endpoint to open the private endpoint details page and then click Edit.
3. Modify the private endpoint name and DNS zones.
4. Click Save Changes.

Here's how you move a private endpoint to a different compartment:

1. From the Data Catalog page in the Console, click Private Endpoints.
2. From the Private Endpoints list, click the Actions menu (
   ) for the private endpoint you want to move and select Move Resource.
3. Select the new compartment for the private endpoint resource.
4. Click Move Resource.

Here's how you detach a private endpoint from a data catalog.

1. From the Data Catalogs page in the Console, click the Actions menu (
   ) for the data catalog where you want to detach a private endpoint and then select Detach Private Endpoint.
2. From the Detach Private Endpoint dialog, click Yes, Detach.

A notification displays indicating that the private endpoint is being detached from the data catalog. A notification is also displayed after the private endpoint is detached successfully from the data catalog.

Important

The data catalog data assets that use the private endpoint that you detached from the data catalog can no longer be harvested again.

Caution

If you attempt to delete a private endpoint that is still attached to a data catalog, you receive a warning that the private endpoint can't be deleted. You must first detach the private endpoint from that data catalog and then delete the private endpoint.

Here's how you delete a private endpoint:

1. From the Data Catalog page in the Console, click Private Endpoints.
2. From the Private Endpoints list, click the Actions menu (
   ) for the private endpoint you want to delete and select Delete.
3. In the Delete Private Endpoint dialog, type DELETE to confirm that you want to delete the private endpoint and then click Delete.

Important

The data catalog data assets that use the private endpoint that you deleted can no longer be harvested again.
