External Database-related Prerequisite Tasks

To enable and use Database Management for External Databases, you must review and complete the prerequisite tasks listed in the following table.

The External Database service is an Oracle Cloud Infrastructure service, which enables you to connect to an Oracle Database that is located outside of Oracle Cloud Infrastructure.

Task Description More Information
Install Management Agents The Oracle Cloud Infrastructure Management Agent service enables the communication and data collection between Database Management and an External Database.

You must install a Management Agent on a host that has a connection to the External Database. Database Management will use the Management Agent for operations such as collecting data and metrics from the External Database.

Note that for single instance databases, a Management Agent 201215.1850 or later is required and for RAC databases, a Management Agent 210403.1349 or later is required. A Management Agent 210403.1349 or later is required for External Databases to use AWR Explorer.

For information on how to install Management Agents, see Management Agent.

If you encounter issues when installing the Management Agent, see Issues Encountered When Enabling Database Management for External Databases for the likely cause and solution.

Register the Oracle Database with the External Database service You must ensure that you register the Oracle Database by creating a resource or handle in the External Database service. This handle functions as a representation of the Oracle Database located outside of Oracle Cloud Infrastructure. For information on how to create an External Database handle, see Creating External Database Handles.
Connect the Oracle Database to the External Database handle After creating an External Database handle, you must connect the Oracle Database that you want to monitor and manage using Database Management to the handle.

Note that you can use TCPS protocol to securely create a connection to the Oracle Database and monitor and manage it.

For information on how to connect an Oracle Database to an External Database handle, see Creating and Managing an External Database Connection.
