Oracle Management Agent (Management Agent) is deployed on each monitored host.
To managing and maintaining the hosts and its targets and communicating that information to the middle-tier Oracle Management Service.
Management Agent also monitor non-oracle components, such as third-party databases, through management plug-ins and connectors.
Backing Up Management Agents
There are no special considerations for backing up Management Agents. As a best practice, reference Management Agent installs should be maintained for different platforms and kept up-to-date in terms of customizations in the emd.properties file and patches applied. Use Deployment options from the Cloud Control console to install and maintain reference Agent installs.
If a Management Agent is lost, it should be reinstalled by cloning from a reference install.
