9. Who Uses OEM?
•OEM is intended for database administrators
and system administrators supporting
enterprise-level infrastructure.
•Organizations heavily invested in Oracle-
based infrastructure gain the most significant
benefits among potential users, since this is a
first-party enterprise management tool.
•However, other companies can find
significant value even if you have a limited
Oracle focus.

10. Why Do Organizations
Choose OEM?
•Oracle has a rock-solid reputation for offering
enterprise-grade solutions that are powerful and secure.
•Both your on-premises and Oracle Cloud-based
technologies are supported, along with a long list of
other assets.
•OEM has been in development for 20 years & Oracle
continually releases improvements that enhance this
platform.
•Automation, database optimizations, user experience
– a win for a DBA.
•Extensions combined with flexibility.

12. Intelligent Incident Compression
(Smart Alerting)
•“Flood of Alerts” experienced with 11g and/or 12c OEM
•With the release of Enterprise Manager 13c, Intelligent Incident Compression allows
multiple events to be automatically grouped into a single incident.
•Situations where it’s useful to deal with multiple related events as a single incident are:
•Consolidation of events from targets on same host.
•Merging of all Tablespace Used (%) alerts across all tablespaces for a particular database
into a single incident.
•You want to automatic union of all Metric Collection Errors for a target into a single incident.
•By compressing notifications, we can manage related events as one unit.
•This is now happening by default due to update 12!

15. Chef Job Support
•Chefis a declarative configuration
management and automation platform.
•Chef has become popular for its concept of
“infrastructure as code,” in which machine-
readable files called Chef recipes are used
to provision infrastructure including
computing hardware and networking.
•Chef recipes are now supported with a new
job type introduced in 13c Enterprise
Manager Cloud Control.

16. Chef Job Support
•You can now manage and access Chef cookbooks
and Chef recipes in the software library.
•The execution of chef recipes is now supported
by deployment procedures.
•You can store Chef cookbooks and Chef recipes
in the software library or even locally to a host
where it gets executed:
•Must have chef-solo setup
•Create a folder in Software library
•Chef cookbook should be uploaded
•Create an OEM job using the new Chef job type
and submit it

17. Chef Job Support

18. Always-ON Monitoring
•THE WAIT IS OVER for monitoring
targets in critical and down alerts
when OEM is down for a planned
maintenance or unavailable during
an outage with Always-ON
Monitoring.
•Always-ON Monitoring (AOM) is a
lightweight application that is
included in 13c Cloud Control.
•You can enable AOM monitoring by
following a few simple steps in OEM.
•The Administrator can enable notifications as and when
required, but it’s best practice to keep AOM running all
the time and notifications can be enabled as per
requirement.
•The monitoring configuration of targets and
notifications data including contacts and email gateway
configuration synchronized with Always-ON Monitoring
as it will be reusing existing configuration of Enterprise
Manager.
•Once AOM is properly setup and synchronized, the EM
notifications can be received even when Enterprise
Manager services are unavailable.

20. Notification Blackouts
•Notification Blackout disables
notifications during the blackout
period on the targets which are under
notification blackout.
•There are two types of Notification
Blackouts:
•Maintenance Notification Blackout
•Notification-only Notification Blackout

21. Notification Blackouts

22. Retroactive Blackout

23. System Broadcast
•Best practice is to notify users currently connected to Enterprise Manager about
outages before any planned maintenance.
•Oracle introduced a new feature in 13c Cloud Control known as System Broadcast.
•The super administrator can notify all users who are connected to Enterprise Manager
by sending a message before any planned maintenance work.
•The EMCLI provides new send_system_broadcast verb using which we can send
message including severity levels.
•Based on the requirement you should set necessary user preferences for System
Broadcasts

24. Example:
emcli send_system_broadcast -
messageType="INFO" -
toOption="ALL" -
message="Enterprise Manager will
be taken down in an hour for an
emergency patch"
System Broadcast

25. EMCLI Extra
emclilogin -username=dvdba
emclisync
emcliget_targets-noheader-script | awk '/listen/{print $4":"$3":Lifecycle
Status:Stage"}'>oem.txt
emcliset_target_property_value-property_records="REC_FILE" -
input_file="REC_FILE:oem.txt" -separator=property_records="\n"
awk '{if ($0 ~/PRD/) {print $0"Production"} else {if($0 ~/DEV/){print $0"Development"}
else {print $0"Test"}}}' oem.txt >oem2.txt

26. Export and Import of Incident Rule Sets
•Exporting incident rule sets from One Enterprise Manager site into another is now available in
13c Cloud Control.
•Mimic the rule set with multiple Enterprise Managers without redoing the configuration of
incident rule sets manually.
•Please Note: The rulesets along with incident rules, users, recipients’ email addresses, targets
on which ruleset are configured and notification methods can also be exported.
•If any of these entities are already available in the target Enterprise Manager cloud control then they will be
kept in the rule set, else they are removed during the import to target site.
•Standardizes the notification rule sets across multiple enterprise managers in the global
complex environment where multiple Enterprise managers are hosted in different data centers.

27. Export and Import of Incident Rule Sets

28. Metric Enhancements
•In previous releases of OEM, users extended
monitoring by creating user defined metric -
which had limited functionality and was
available only for a few known target types.
•In 13c Cloud Control, the metric extensions
allow you to create full-fledged metrics for a
multitude of target types:
•Hosts
•Databases
•Oracle Exadata databases and storage servers
•Siebel components
•Oracle Business Intelligence components
•Fusion Applications IBM WebSphere
•Advantages of Metric Extensions
•Metric Comparison operators can now be modified
for alerts.
•Compute expressions are now supported in metric
extensions.
•Metric extensions are can be setup for RAC and
NON-RAC (single instance) databases.
•These enhancements in Metric extensions
provide better monitoring and flexibility to
meet requirement of monitoring complex
environments.
