5. INTRODUCTION TO EM13C
WHAT IS ENTERPRISE MANAGER CLOUD CONTROL?
▸ Enterprise Manager Cloud
Control provides a centralized
monitoring and management
platform for IT infrastructure.
▸ Enterprise Manager can manage
and monitor various targets (host,
ASM, RAC, Database, Listener,
Weblogic, Tomcat, Apache and
more), and it’s possible to add
more target types using plugins.

6. INTRODUCTION TO EM13C
ENTERPRISE MANAGER CLOUD CONTROL ARCHITECTURE
▸ Agents: Collect monitoring
and configuration data from
the targets and executes
tasks
▸ Management Server (OMS):
Receives and processes
data from Agents, Provides
UI and Target Specific
Management
▸ Repository (OMR):
Persistent store for data
collected from the
managed TargetsNotifications
Connectors
Console (web/cli)

39. HOW TO BACKUP
BACKUPS
You need to back up following components:
▸ The Oracle Management Service: Filesystem backup of
installed software* and backup of OMS configuration:
$OMS_HOME/bin/emctl exportconfig oms
▸ The Management Repository: Backups can be taken using
RMAN
▸ The software library: Taking file system backups daily is
sufficient in most cases.
