You have three databases, FINDB, PAYDB and ADMINDB, located in Sydney, Tokyo and Singapore respectively. You want to perform administrative tasks which include starting up and shutting down the databases, creating and managing tablespaces and database users, and taking regular backups, for all of the three databases from London.
Which component must be enabled and running on each host machine to achieve your objective?
A. Oracle Management Agent
B. Enterprise Manager with Grid Control
C. Enterprise Manager with Database Control
D. Operating System Socket for incoming requests
E. Real Application Cluster (RAC) with three instances
F. Enterprise Manager with Generic Database Management
Answer: A
If you are using Oracle Enterprise Manager Grid Control to manage multiple Oracle products from a central location, then you must have an Oracle Management Agent installed on each host system. Typically, the Oracle Management Agent is installed in its own Oracle home directory.
4 Enterprise Configuration Management
You can use Grid Control to view, save, track, compare, and search the configuration information stored in the Management Repository for individual hosts, databases, application servers, clients, and non-Oracle systems in the entire enterprise.
Enterprise Manager collects configuration information for all hosts and the managed targets on those hosts that have a running Management Agent. The agent periodically sends the configuration information to the Management Repository over HTTP or HTTPS, allowing you to view up-to-date configuration information for your entire enterprise through Grid Control.
