• Why use OEM 12c?
Single Interface for all Engineered Systems
Connectivity between OEM and EMOC for Exalogic for
alerts (management?)
Use of monitoring templates, administration groups and
roles already created
Notifications
Automation of tasks using Job system and corrective
actions
Motivation

• OEM 12c Architecture
• Oracle OMS, Repository and Agents
• OEM 12c plug-ins
• Plug-ins for Exadata, Exalogic and Exalytics
• Engineered Systems Architecture
• Exadata DB Machine
• Exalogic Elastic Cloud
• Exalytics In-Memory Machine
• Enabling Monitoring
• Install, discover and configure components
• Customize monitoring and automate tasks
• Tools
• Repvfy and Exachk

Enabling Monitoring

• Prerequisite steps before discovering Exadata
DB machine within Oracle Enterprise Manager
12c (Doc ID 1437434.1)
1. Create a Database Server ILOM Service Processor User
(nm2user)
2. Verify permissions. The account running the OEM agent
should have read/execute on $ORACLE_HOME/bin/kfod
binaries
3. Verify the versions. Exadatas before 2011 should have
unsupported versions of the schematic files
4. Verify the values of <ADMINNAME> and <ADMINIP> for
components
5. Others
Enabling Monitoring

• Install OEM 12c Agent on compute nodes

Enabling Monitoring

Install OEM 12c Agent
Prerequisites
Import Ops Center Certificate into Agent’s Keystore
Import OVM Manager Certificate into the Agent
Set OVMM to Read-Only mode
Discover Oracle VM Manager
Discover Oracle ZFS Storage Appliances
Discover the Exalogic Elastic Cloud Target
Enabling Monitoring

Import Ops Center Certificate into Agent’s Keystore
Login as root to the EMOC host
Change directory to
[root@localhost~]# cd $OPS_CENTER_HOME/oem-
ec/security/jsse
Export the Certificate
[root@localhost jsse]# $JAVA_HOME/jre/bin/keytool -
export -alias cacao_agent -file oc.crt -keystore
truststore -storepass trustpass
Import the Certificate into Agent’s Keystore

$AGENT_HOME/agent_inst/sysman/config/montrust/AgentTr
ust.jks -alias <alias_name> -file
<path_to_oc_certificate_file>/oc.crt
Bounce the Agent
Enabling Monitoring

Import the OVMM Certificate into the Agent
As root on the OVMM host
cd /u01/app/oracle/ovm-manager-3/
/opt/oracle/em12c/agent/core/12.1.0.3.0/jdk/bin/keyto
ol -keystore ./ovmmCoreTcps.ks -exportcert -alias
ovmm -file ovmm.cr
Password: <Enter>
As the OEM Agent user on the OVMM host
$AGENT_HOME/bin/emctl secure add_trust_cert_to_jks -
trust_certs_loc <Location of the Oracle VM Manager
Certificate> -alias ovmm
Password: <Enter>
Bounce the OEM Agent
