Private Source Limitations - Canonical Host Names

You can't use canonical host names to connect to private data sources over a private access channel. This means that if you want to connect to private data sources such as Snowflake that use AWS PrivateLink, you must create a private DNS zone (in the same VCN as the private access channel) with A records to map the private data source host names to private IP addresses. Then, you must add this private DNS zone to the private access channel.

• DNS Zone: Specify domain names such as companyabc.com, example.com, myoacvcn.oraclevcn.com, and so on.
• SCAN Host and Port: Specify host names such as db01-scan.corp.example.com, prd-db01-scan.mycompany.com, and the port where the SCAN protocol connects, for example 1521.
