## 21.1.9 Enabling Network Services in Oracle Database

Database administrators must enable network services in Oracle Database to send outbound mail, invoke web services, or use template-based PDF report printing with external print servers in Oracle APEX.

Note:

Enabling network services does not apply to APEX instances running on Oracle Autonomous AI Database. APEX can communicate with external endpoints over the internet without additional configuration.
