Note:
Functionality in the Administration Services application is not available in Oracle Database Cloud Service (Database Schema).Instance administrators are superusers that are responsible for managing an entire Oracle Application Express instance. Instance administrators manage workspace provisioning, configure features and instance settings, and manage security. To perform these tasks, an Instance administrator signs in to the Oracle Application Express Administration Services application.
Tip:
To learn more about creating an Instance Administrator account in a new installation, see the "Creating or Updating Your Instance Administration Account" section for your Web Listener in Oracle Application Express Installation Guide.
