Perform these tasks to install the Oracle Enterprise Manager Agent and deploy the plug-in.
Topics:
The following is an overview of the tasks that you need to perform to begin monitoring Oracle Database Appliance systems.
Install the Oracle Enterprise Manager Agent
Deploy the plug-in
Discover Oracle Database Appliance systems to add the targets for monitoring
(Optional) Configure the monitoring metrics and notifications
After Oracle Enterprise Manager Cloud Control discovers the targets, the software begins monitoring the supported hardware and software components.
Before deploying Oracle Database Appliance plug-in, ensure that you complete the prerequisites.
Complete the following prerequisites:
Create a special user for the Oracle ILOM service processor.
For the Oracle Enterprise Manager agent to communicate with an Oracle Integrated Lights Out Manager (Oracle ILOM) service processor, you must have a specific user ID configured for the Oracle ILOM service processor.
Note:
Adding the specific user ID requires administrator level privilege on the Oracle ILOM service processor.
The specific Oracle ILOM user ID can be added in the Oracle ILOM service processor web interface, Oracle ILOM CLI, or with the ipmitool command. This example uses the Oracle ILOM CLI.
For security reasons, the root user password to the Oracle ILOM service processor is not shown in the Oracle ILOM CLI commands in this example.
Log in to the Oracle ILOM Service Processor as root:
# ssh root@[Service Processor IP] Password:
Change to the users directory:
-> cd /SP/users
Create the oemuser user and password:
-> create oemuser Creating user... Enter new password: ******** Enter new password again: ******** Created /SP/users/oemuser
Change to the new user's directory and set the role:
-> cd oemuser /SP/users/oemuser -> set role='cro' -> Set 'role' to 'cro'
Test the Oracle ILOM user ID created in step 3 by listing the last 10 system events:
-> ipmitool -I lanplus -H -U oemuser -P welcome1 -L USER sel list last 10
Repeat steps 1 through 5 for the rest of the server node Oracle ILOM service processors in Oracle Database Appliance.
(Optional) Create a special user for monitoring instead of using the root user.
The root user can perform monitoring on Oracle Database Appliance agents. However, if the root user is not accessible for security reasons, an alternative method is to create a monitoring OS user as the monitoring user, and set the privilege delegation appropriately. If you run a virtualized ODA, please perform the following steps from ODA_BASE.
The following is an example that creates user for the purpose of monitoring Oracle Database Appliance.
Run the following commands:
#useradd username #passwd password
Add SUDO privilege for the user.
Modify the /etc/sudoers file on the host using the visudo command.
Add the following commands to the /etc/sudoers file.
Cmnd_Alias plugin_agent_script=$perl_home/bin/perl $agent_home/plugins/$plugin_opar_version /scripts/*.pl* , \ $agent_home/sbin/nmosudo default_plugin default_functionality default_subaction default_action perl -e exit 0 monitor_user ALL=(ALL) plugin_agent_script
Note that:
$agent_home is the absolute path to the installed agent home. The agent home directory is created during agent deployments to the hosts. For example, /u01/app/agent_home/
$perl_home is the absolute path to the installed executable Perl. For example, /u01/app/agent_home/core/12.1.0.5.0/perl/
$plugin_opar_version is the complete Oracle Database Appliance Plug-in OPAR file that is deployed to the Oracle Management System (OMS) and the agents. It is in the format:
oracle.dba.odba.agent.plugin_version
version is the Oracle Database Appliance plug-in version, for example, 13.2.2.1.0.
Set privilege delegation to the host targets.
Log in to Oracle Enterprise Manager.
In the Setup menu select Security, then Privilege Delegation.
Select Edit.
In the Type box, select Sudo.
Enter /usr/bin/sudo -u %RUNAS% %COMMAND% in the Sudo Command box.
Click Save.
Verify that you have a supported version of Oracle Appliance Manager software installed.
To verify the software version on Oracle Database Appliance X7-2S, X7-2M, X6-2S, X6-2M, and X6-2L, run the command:
# odacli describe-component
To verify the software version on Oracle Database Appliance X7-2-HA (bare metal platform) run the command:
# odacli describe-component
Verify the version on both nodes. The command provides details across all nodes.
To verify the software version on Oracle Database Appliance X7-2-HA (virtualized platform), run the command:
# oakcli show version
To verify the software version on Oracle Database Appliance X6-2-HA, X5-2, X4-2, X3-2, and V1 (bare metal or virtualized platform), run the command:
# oakcli show version
Verify the version on both nodes.
Validate the Oracle Database Appliance storage topology and external JBOD connectivity before deploying Oracle Database Appliance. You should also validate the connections after changing the cabling.
Verify that each server node is able to resolve the host names of the Oracle ILOM servers.
If the names of those components are not registered in DNS, then entries can be added to the /etc/hosts file of each server node.
Use one of two methods to install the Oracle Enterprise Manager Agent for Oracle Database Appliance.
Topics:
Deploy the Oracle Enterprise Manager agent on ODA_BASE for Oracle Database Appliance Virtualized Platform deployments, and in Linux Hosts for Oracle Database Appliance Bare Metal deployments.
Oracle Enterprise Manager target discovery supports the use of either the management network host name or the client network host name for the server nodes. When you install the Oracle Enterprise Manager agent on the server nodes, use the same host name you used in Oracle Clusterware.
You can identify the host name of the nodes in the cluster by running the olsnodes command on one of the server nodes. It is recommended that a fully qualified host name, including the domain name, be used when specifying an Oracle Enterprise Manager agent host name.
Note:
Before deploying the agent, review the following requirements:
The Oracle Enterprise Manager agent must be deployed to all server nodes of Oracle Database Appliance. The host target name of the server node must be the fully qualified host name, for example, dbm1db01.mydomain.com.
A non-fully qualified host name (for example, dbm1db01) or IP address must not be used for the host target name of the server node.
The same version of the Oracle Enterprise Manager agent and the same version of the plug-ins should be deployed on all server nodes within the same Oracle Database Appliance.
Use this procedure to install Oracle Enterprise Manager Agent using the Push method.
To install the Oracle Enterprise Manager agent using the push method, add the Oracle Database Appliance server nodes as host targets to Oracle Enterprise Manager Cloud Control 13c, and then start the agent deployment process.
Note:
If the root.sh was not executed during deployment, then make sure to execute it on all server nodes.
Use this procedure to install Oracle Enterprise Manager Agent using a response file.
You can install Oracle Management Agent in non-interactive (“silent”) mode, as an alternative to installing Oracle Management Agent by using the Add Host Target wizard. You configure a response file with the information required for the installation, and then run a deployment script to install the management agent using the information supplied in the response file.

*.opar).EMCLI on a different system than the system where you created the plug-in archive (*.opar file).The Oracle Enterprise Manager Plug-in for Oracle Database Appliance is delivered as an Oracle plug-in archive file (*.opar).
The plug-ins belong to a specific Oracle Enterprise Manager category called Add-on. If you are using Oracle Enterprise Manager 12c to monitor Oracle Database Appliance, download the latest 13c compatible version of the plug-in and follow the instructions to invoke the Enterprise Manager Cloud Control Installer in GUI Mode before starting the Enterprise Manager 13.2 upgrade process.
The Enterprise Manager for Oracle Database Appliance plug-in archive file (*.opar) is named oda_plugin_version_number_oracle.dba.odba_2000_0.opar. The oda_plug_in_version number is the Oracle Database Appliance plug-in version, the plug-in version is not the same as the Oracle Database Appliance version. The latest Oracle Database Appliance plug-in version for Enterprise Manager 13.2 is named 13.2.2.1.0_oracle.dba.odba_2000_0.opar.
Assuming you plan to use an existing Oracle Enterprise Manager installation, and that you have installed an Oracle Enterprise Manager agent, you are ready to deploy the Oracle Database Appliance plug-in.
Note:
Before deploying the plug-in, you must have already completed the Oracle Database Appliance deployment, and the Oracle Grid Infrastructure cluster should be up and running.The following is a high-level overview of the steps to deploy the plug-in:
Download the Enterprise Manager for Oracle Database Appliance plug-in archive file from http://www.oracle.com/technetwork/oem/enterprise-manager/downloads/oem-plugins-3237574.html.
Either import the Oracle Database Appliance plug-in archive locally, or import the Oracle Database Appliance plug-in archive file remotely.
Deploy the Oracle Database Appliance plug-in on Oracle Enterprise Manager Cloud Control (Oracle Management System Servers).
Deploy the Oracle Database Appliance plug-in to the management agents on both Oracle Database Appliance server nodes (hosts).
