Methods for Connecting Oracle Integration to an Oracle Autonomous Transaction Processing - Dedicated Database Instance with the Oracle Autonomous Transaction Processing Adapter

Connectivity from Oracle Integration to an Oracle Autonomous Transaction Processing- Dedicated database instance using the Oracle Autonomous Transaction Processing Adapter can be accomplished through the following methods.

• Connectivity agent: Use this approach when the Oracle Autonomous Transaction Processing - Dedicated database instance is not publicly accessible and resides within a private subnet in your Virtual Cloud Network (VCN). With this topology, the Oracle Autonomous Transaction Processing Adapter cannot directly access the Oracle Autonomous Transaction Processing- Dedicated database instance. The connectivity agent must be deployed in your network to allow the connectivity agent access to the Oracle Autonomous Transaction Processing- Dedicated database instance.
• Direct connectivity: Use this approach when the Oracle Autonomous Transaction Processing - Dedicated database instance is directly accessible from Oracle Integration. In this case, the connectivity agent is not necessary. However, Oracle strongly recommends using Transport Level Security (TLS ) for the communication between Oracle Integration and the Oracle Autonomous Transaction Processing- Dedicated database instance to ensure the data being transmitted is encrypted in motion.
