AGENDA
• Introduction to Enterprise Manager 13c
• Architecture of Enterprise Manager
• Components involved
• Overview of New & Enhanced Features in 13c
INTRODUCTION TO OEM13C
ORACLE ENTERPRISE MANAGER- WHY?
• Provides a centralized monitoring and management platform for IT
infrastructure.
• One tool to monitor and manage all Oracle databases.
• Can manage and monitor various targets (host, ASM, RAC, Listener,
Weblogic, Tomcat, Apache and many more).
• It’s possible to add more target types using plug-ins.
• Easy to maintain: Familiar components (Oracle products), My Oracle
Support.
KEY CAPABILITIES OF OEM13C
• Oracle Enterprise Manager 13c therefore introduces “always on”
monitoring
• Planned downtime windows - another exciting feature being
introduced is “notification blackouts”
• “Stack management” - unification of hardware and software
management
• “Infrastructure management” - target types: servers, storage, network,
VMs in Enterprise Manager.
• “Integration of Exacheck” - generate automated notifications and
reports for any violation in their Exadata configurations.

ORACLE MANAGEMENT AGENT
• Converts an un-managed host to a managed host in OEM.
• Working in conjunction with the plug-ins to monitor targets
running on a host.
• “Central Agent” {Default Agent – to monitor OMS host}
• Standalone management agent.

Information collected by agent gets stored
OMS upload data received from Agents
OMR organize data so that it can be retrieved by OMS and displays in
console
• At the time of installation, OEM installation wizard configure OMS in
your existing certified database
•

•
PLUG-INS
• Pluggable entities
• Offer special management capabilities
• Plug-ins works in conjunction with the OMS, the management agent
to monitor every target
• Deployed to both OMS and Agent as well
• Earlier release, plug-in enabled to monitor only 3rd Party targets,
now all types of targets
• Independent release cycles
ORACLE JVMD ENGINE
• Java Virtual Machine Diagnostics
• Enables to diagnose performance issues in java application.
• Eliminate need to reproduce problems
• Reduce time required to resolve these problems, improves
application availability & performance
• From 13c, one JVMD Engine is installed by default with
Fusion Middleware Plug-in
• JVMD agents have to be manually deployed on JVM’s
ORACLE BI PUBLISHER
•
•
•
•
•
Primary reporting tool.
Provide pixel-perfect reports & dashboard
Huge variety of report & dashboard layouts
From 13c, BI Publisher is installed and configured by default

EM CLI & EMCTL
 EM CLI enables users to access Enterprise Manager functionality
through a command-line interface or scripts.
 EM CLI is fully integrated with Enterprise Manager's security and user
administration functions.
 Examples of EM CLI tasks you can accomplish are as follows:
 Create a new Enterprise Manager administrator account.
 Monitor and manage targets, jobs, groups, and blackouts.
 EMCTL is a command line utility installed with EM to administer or
control the core components of Enterprise Manager Cloud Control,
particularly Oracle Management Service (OMS) and Oracle
Management Agent (Management Agent).

INCIDENT COMPRESSION
 Events related to same issue can be combined together.
 Criteria for grouping includes: By target
 By event category
 By metric
 Time window can also be used to group events
 Event grouping reduces over all volume of Incidents
created.

Always-On-Monitoring
• Provides continuous monitoring of target down or other critical
alert even while EM is under maintenance.
