Oracle Exalogic is an engineered hardware and software system designed to provide the ideal platform for the Oracle Fusion Middleware and business applications. By deploying Exalogic Elastic Cloud, you can increase the performance and efficiency of existing Linux, Solaris and Java applications and improve application and infrastructure reliability, scalability and availability.The Oracle Exalogic Elastic Cloud is a system consisting of software, firmware and hardware, on which you can deploy Oracle business applications and Oracle Fusion Middleware or software. Exalogic dramatically improves performance of standard Linux, Solaris and Java applications and reduces costs across the application lifecycle.Oracle Exalogic Elastic Cloud is modeled as a system target rather than a group target within Enterprise Manager Cloud Control. The following targets can comprise the Oracle Exalogic Elastic Cloud:
Infiniband Network - An Infiniband Network has IB Switches as members. This is a one to many association.
SOA Infrastructure
WebLogic Domains
Coherence Clusters
OTD
Hardware Targets (such as PDU, CISCO Switch, ZFS, and ILOMs)
For more information about adding assets to Exalogic which can then be used for monitoring on Enterprise Manager Cloud Control, refer to the documentation at the link below:

There are several steps you must perform before you can discover Oracle Exalogic Elastic Cloud in Enterprise Manager Cloud Control. The following sections outline these steps in detail and provide you with the information you need to set up the Exalogic Elastic Cloud targets:
Importing Ops Center Certificate to the Oracle Management Agent Keystore
ZFS Plug-in and Oracle VM Manager Registration Preconfiguration Steps
This section provides step-by-step instructions about how to export the certificate from the Enterprise Manager Ops Center keystore and how to import the certificate into the Enterprise Manager agent keystore. These steps are a prerequisite for Exalogic Elastic Cloud discovery in Enterprise Manager Cloud Control.
Use these steps to export the Ops Center Enterprise Controller trust certificate and import it to the Enterprise Manager Cloud Control Management Agent:
Change directory to OPS_AGENT_HOME/oem-ec/security/jsse where OPS_AGENT_HOME is the path to the Oracle Enterprise Manager Ops Center home. For example, /etc/opt/sun/cacao2/instances/oem-ec/security/jsse:
[root@localhost~]# cd OPS_AGENT_HOME/oem-ec/security/jsse
This directory change is on the VM where the Ops Center Enterprise Controller is running.
Export the certificate using keytool that corresponds to the JDK configured to run Ops Center
[root@localhost jsse]# $JAVA_HOME/jre/bin/keytool -export -alias cacao_agent -file oc.crt -keystore truststore -storepass trustpass
This command exports the certificate file (oc.crt) in the local directory, for example, OPS_AGENT_HOME/oem-ec/security/jsse. In the above command, trustpass is the default password for the Ops Center keystore unless changed. The Ops Center Certificate is stored in file oc.crt. You can import the Ops Center certificate to the Oracle Management Agent TrustStore using the following steps. The Agent used for communication with Enterprise Manager Ops Center should be running on the same host instance. If it is not, transfer the certificate to the host instance where the agent that you want to configure is running.
Change directories to the agent home, where $OMS_AGENT_HOME is the Oracle Management Agent home:
cd $OMS_AGENT_HOME/core/12.1.0.2.0/stage/sysman/config/montrust
Enter the following command:
$OMS_AGENT_HOME/agent_inst/bin/emctl secure add_trust_cert_to_jks -trust_certs_loc $CERT_LOC/oc.crt -password welcome -alias wlscertgencab
Alternatively you can enter this command:
[root@localhost montrust]# $JAVA_HOME/jre/bin/keytool -import -keystore $OMS_AGENT_HOME/core/12.1.0.2.0/stage/sysman/config/montrust/AgentTrust.jks -alias wlscertgencab -file $CERT_LOC/oc.crt
When prompted, enter the password welcome unless changed from the default, and click Enter.
If you follow this step for exporting the certificate, the path to the certificate file will be OPS_AGENT_HOME/oem-ec/security/jsse/oc.crt
Alternatively, you can also do the following:
Export the certificate.
Copy the certificate to $OMS_AGENT_HOME/core/12.1.0.2.0/stage/sysman/config/montrust
Change the directory using the following command:
cd $OMS_AGENT_HOME/core/12.1.0.2.0/stage/sysman/config/montrust
Run the import command as mentioned. For example:
$JAVA_HOME/jre/bin/keytool -import -keystore $OMS_AGENT_HOME/core/12.1.0.2.0/stage/sysman/config/montrust/AgentTrust.jks -alias wlscertgencab -file oc.crt
To verify that the certificate has been imported correctly, run the following command:
[root@localhost montrust]# $JAVA_HOME/jre/bin/keytool -list -keystore $OMS_AGENT_HOME/core/12.1.0.2.0/stage/sysman/config/montrust/AgentTrust.jks
You should see the entry for wlscertgencab alias you created in the output.
After verifying that the certificate has been successfully imported, restart the agent by using the stop and start procedure in the following documentation:
http://docs.oracle.com/cd/E25054_01/doc.1111/e24473/emctl.htm#BABEFBDI
Warning:
Exalogic configurations supporting virtualization must each have Oracle Virtual Machine Manager (OVMM) properly configured for read-only access by Enterprise Manager Cloud Control as a mandatory requirement as described in the following procedure. Failure to configure each Oracle Virtual Machine Manager (OVMM) for read-only access by Enterprise Manager Cloud Control will result in an unsupported configuration. Operations performed in this unsupported configuration may result in software outages and necessitate the re-installation of the Exalogic Control software.If OVMM was registered with Enterprise Manager Cloud Control prior to performing the OVMM-Enterprise Manager read-only configuration procedure above, then you must choose Synchronize Operation from the OVM Manager Target menu in Enterprise Manager.
You must perform the following steps as a prerequisite to OVMM discovery:
Login to OVMM vServer as oracle user, and then perform the commands in the sequence below.
cd /u01/app/oracle/ovm-manager-3/ovm_shell
sh ovm_shell.sh --url=tcp://localhost:54321 --username=admin --password=<ovmm admin user password>
ovm = OvmClient.getOvmManager ()
f = ovm.getFoundryContext ()
j = ovm.createJob ( 'Setting EXALOGIC_ID' );
The EXALOGIC_ID can be found in the em-context.info on dom0 located in the following file path location:
/var/exalogic/info/em-context.info
You must log in to dom0 as a root user to obtain this file. For example, if the em-context.info file content is ExalogicID=Oracle Exalogic X2-2 AK00018758, then the EXALOGIC_ID will be AK00018758.
j.begin ();
f.setAsset ( "EXALOGIC_ID", "<Exalogic ID for the Rack>");
j.commit ();
Ctrl/d
You can validate the configuration following these steps by observing that several menus for the manager/pool/server/guest vm target are disabled. Specifically, you can validate that OVM Manager is in read-only mode by right-clicking the registered OVM manager under Infrastructure Cloud.
All the active operation menu items in the second and third tier of the list, such as Create Zone, Create Virtual Server Pool, and Manage Network, are disabled (grayed out) and are not available for selection. Conversely, if you choose an item from the pull-down menus that are displayed when you click either the VM Manager or VM Guest menu option, the same menu items may not be grayed out. However, if you select one of the active management options, Enterprise Manager displays an error message stating that the action cannot be performed, thus indicating that the OVM Manager is in read-only mode.
For virtualized Exalogic configurations, there are several preconfiguration steps you must complete. The first configures the Enterprise Manager Cloud Control ZFS plug-in (optional), the second registers the Oracle VM Manager with Enterprise Manager Cloud Control (mandatory), and the third configures the Exalogic Guest Base Template and the Exalogic network.
For non-virtualized Exalogic configurations, the ZFS plug-in can be configured in step one outlined below as part of a recommended but optional configuration:
Configure the ZFS Plug-in
It is recommended that the agent used for the ZFS configuration reside on the same host as the Exalogic Enterprise Controller. If an Enterprise Manager Cloud Control Agent is not present on the vServer, deploy one using the following documentation:
http://docs.oracle.com/cd/E24628_01/install.121/e22624/install_agent.htm#CACJEFJI
Install and Configure the Enterprise Manager Cloud Control ZFS plug-in using the following documentation:
http://download.oracle.com/otn/java/oem/Oracle_GC_Plugin_Installguide.html
Register the Oracle VM Manager with Enterprise Manager Cloud Control
Use the Enterprise Manager Cloud Control Agent deployed on the same vServer as the OVM Manager. If an Enterprise Manager Cloud Control Agent is not present on the vServer please deploy one using the following documentation:
http://docs.oracle.com/cd/E24628_01/install.121/e24089/part_installing_agent.htm
In order to see Exalogic vServers in the Enterprise Manager 12c Exalogic navigation tree you must register the Oracle VM Manager with Enterprise Manager Cloud Control. Please use the following documentation as a guide:
http://docs.oracle.com/cd/E24628_01/doc.121/e28814/cloud_setup.htm#CEGICIFE
As a prerequisite for Enterprise Manager management of a virtual Exalogic configuration the Exalogic Guest Base Template and Exalogic network must be configured according to the following documentation:
http://docs.oracle.com/cd/E24628_01/doc.121/e35776/emexl.htm
You can use the Exalogic Elastic Cloud Discovery wizard to discover and monitor an Exalogic target in Enterprise Manager.
The Exalogic Elastic Cloud Discovery process identifies the targets present in the Exalogic Elastic Cloud and maps them to Enterprise Manager targets, then adds Enterprise Manager targets as Exalogic Elastic Cloud system members.
To use the Exalogic Elastic Cloud Discover wizard, follow these steps:
In Enterprise Manager, navigate to the Systems page.
From the Add drop-down list, choose Exalogic Elastic Cloud and click Add.
Enterprise Manager displays the Discover Exalogic Elastic Cloud page which allows you to enter the parameters and values required to discover an Oracle Exalogic target.
Specify a unique Name for the Oracle Exalogic target you want to monitor in the Name field.
Select an Agent on one of the hosts in the Exalogic System to perform the discovery. For virtual Exalogic configurations, select the agent running on the same vServer as the Exalogic enterprise controller. If an Enterprise Manager Cloud Control Agent is not present on the vServer, deploy one using the following documentation:
http://docs.oracle.com/cd/E24628_01/install.121/e22624/install_agent.htm#CACJEFJI
For non-virtual Exalogic configurations, select an Agent on one of the hosts in the Exalogic System to perform the discovery.
If you choose an agent that is not part of the Exalogic System, an error message appears stating that no Exalogic Property File can be found and indicating that you must choose an Agent which is on an Exalogic System Host. For a virtual deployment the host may not have the ID.
Choose the Deployment Type from the drop-down. You can select either Physical or Virtual.
Provide details about the Ops Center Enterprise Controller monitoring the Exalogic Elastic Cloud you want to discover. You must enter information in the Ops Center Host Name field, the Ops Center Port field, and the credentials in the Username and Password fields.
Click Next. Enterprise Manager displays the Discover Oracle Exalogic Targets: Discovered Targets page. The page displays all member targets (such as PDU, Switches, ILOM) that are discovered as part of the system and displays other discovered hardware targets in virtual discovery.
Click Finish to complete discovery. You can also choose Back to return to the Discover Exalogic Elastic Cloud page or Cancel to terminate the discovery process.
Enterprise Manager displays a confirmation that the Exalogic Elastic Cloud instance has been added and begins to monitor the Exalogic Elastic Cloud target. The new target is displayed on the Systems page.
You can upgrade the Exalogic System targets discovered in Enterprise Manager version 11 of Grid Control and Enterprise Manager version 12 of Cloud Control to the 12.1.0.3 Fusion Middleware model. Before you upgrade the Exalogic System targets, however, the Management Agent monitoring the Exalogic System target must also be upgraded and the Management Agent should have the version 12.1.0.3 Fusion Middleware Plug-in.
The upgrade job is available as a library job by choosing Jobs from the Enterprise menu and then selecting Library. Select the job name, Upgrade Exalogic Systems To Fusion Middleware 12.1.0.3.0 Model. The job can be run more than once. Run this job after upgrading the OMS and the Management Agent monitoring the Exalogic System target. If the job is successful, Enterprise Manager displays a confirmation message indicating that all Exalogic systems have been upgraded and the job is complete. If one or more Management Agents monitoring Exalogic System targets are not upgraded, the job will fail. Under such circumstances, first upgrade those Management Agents and then try submitting this job to upgrade the Exalogic System targets.
