What is the default port number for Autonomous Transaction Processing?

The default port number for Autonomous Transaction Processing is 1522. In database connectivity, port numbers are used to identify specific services on a server. For Oracle, the default port for database services such as Autonomous Transaction Processing traditionally includes port 1521; however, with specific configurations like Autonomous Transaction Processing, port 1522 is designated.

This differentiation is crucial as port numbers enable different services to run simultaneously on the same machine without conflicting. Recognizing the correct port number is essential for establishing proper database connections and configurations in typical database management scenarios.

Other port numbers mentioned, such as 8080 and 443, are commonly used for web traffic (HTTP and HTTPS respectively) and are not applicable in the context of Oracle database services.
