OCI Linux

This section describes the steps to set up the Oracle Cloud Agent and deploy the JMS plug-ins on an Oracle Linux Compute Instance using the installation script. For Oracle Linux instances in different region and/or tenancy, and other supported Linux platforms, follow the On-premises Linux instructions to set up Oracle Management Agent.

Note

The recommended approach for onboarding OCI Linux instances to the fleet is using the fleet's Add Managed Instance(s) action in the Managed Instances view. See instructions in the OCI Linux section in the Manual Method for Installing Management Agent and Deploying JMS Plug-in.
In the case of OCI instance pools, you need to individually set up the agent on each instance part of the OCI instance pool.

Prerequisites:

Run the installation script with sudo or administrative access.

Make sure the following policy is added before you run the installation script on OCI Linux instances.

 ALLOW dynamic-group JMS_DYNAMIC_GROUP TO MANAGE instances IN
    COMPARTMENT <instance_compartment_ocid>

See Set up OCI Linux instance for JMS for instructions.

Note

By default, the installation script will:

Generate usage tracker with additional functionality to collect the user.name property for better identification of applications running on Application Servers like WebLogic and Tomcat. If you do not want to enable this feature, update the parameter --enable-user-name=false in the installation script. You can modify the Java Usage Tracker properties file in the future to add or remove user.name from the additionalProperties section.
Disable Federal Information Processing Standards (FIPS) mode for plug-ins. To enable FIPS mode in USGov relams, update the parameter --enable-fips-mode=true in the installation script.
Install the agent with MACS default telemetry frequency.

Run the --help command to view the description of options such as enabling or disabling user name, proxy settings, FIPS, and so on.

The following are the optional parameters along with the description:


-u, --uninstall               Uninstall plug-ins, delete configuration files or restore originals from backups and exit.
-r, --reinstall               Uninstall plug-ins, delete configuration files or restore originals from backups and continue installation.
-h, --help                    Print usage message end exit.
--diagnostic                  Determine if prerequisite conditions are met on the host machine to allow successful 
                              agent installation and plug-in deployment.
--enable-user-name            Generate usage tracker with additional functionality to collect the 'user.name' property for better identification 
                              of applications running on Application Servers like WebLogic and Tomcat servers. 
                              Default value is 'true'. 
--enable-fips-mode            Enable FIPS mode for plug-ins in USGov realms.
                              Format is --enable-fips-mode=true|false (for example, --enable-fips-mode=false).
                              Modify /etc/environment and create a line with ENV_AGENT_PLUGIN_FIPS_APPROVED=true or false.
                              Default value is false.
--install-management-agent    Installation of OMA on the OCI compute instance.                               
--uninstall-management-agent  Uninstallation of OMA on the OCI compute instance.                                 
--reinstall-management-agent  Force OMA installation on the OCI compute instance and remove existing OMA.
--ignore-unsupported          The setup will proceed on an unsupported platform. 
                              Installation might be successful, but not all functionality might work as intended.                               
--proxy-host                  Add proxy host to curl commands, add or replace line 'ProxyHost = VALUE' in install key before Management Agent setup.
                              Format is --proxy-host="VALUE" (for example, --proxy-host="100.0.0.10").
                              Default is no proxy.
--proxy-port                  Add proxy port to curl commands, add or replace line 'ProxyPort = VALUE' in install key before Management Agent setup.
                              Format is --proxy-port="VALUE" (for example, --proxy-port="8050").
--proxy-user                  Add proxy user to curl commands, add or replace line 'ProxyUser = VALUE' in install key before Management Agent setup.
                              Format is --proxy-user="VALUE" (for example, --proxy-user="opc").
--proxy-password              Add proxy password to curl commands, add or replace line 'ProxyPassword = VALUE' in install key before Management Agent setup.
                              Format is --proxy-password="VALUE" (for example, --proxy-password="example").
--proxy-realm                 Add or replace line 'ProxyRealm = VALUE' in install key before Management  Agent setup.
                              Format is --proxy-realm="VALUE" (for example, --proxy-realm="OC1").
--use-agent-installer-path    Path to management agent installation file if it isn't in the same folder as the install script.
--use-java-path               Specify the Oracle Java 8 installation path for agent installation.  
                              If the path is not specified, the script will attempt to find a suitable Oracle Java 8 installation path from the file system. 
                              Format is --use-java-path={CUSTOM_PATH}(for example, --use-java-path=/usr/java/jdk1.8.0_361)).  
--use-agent-display-name      Specify the name to be displayed on the MACS console of your Management Agent.
                              If the name is not specified, the script will generate the name automatically.

Steps

(Optional diagnostic check) Navigate to the folder where you saved the installation script. Run the script using the following command:

$ sudo bash ./JMS_YourFleetName_linux.sh --diagnostic

Depending on the operating system and agent type, the results will be similar to:

Navigate to the folder where you saved the installation script. Run the script using the following command:

$ sudo bash ./JMS_YourFleetName_linux.sh

If installation is successful, you'll see a message similar to the following:

...
Management Agent installation has been completed.
Management Agent plugin 'Java Management Service' installation has been completed.
Management Agent plugin 'Java Usage Tracking' installation has been completed.
Management Agent was successfully registered using key YourFleetName (ocid1.managementagentinstallkey.oc1.iad.<ocid hash>).Assigned JMS Fleet is YourFleetName (ocid1.jmsfleet.oc1.iad.<ocid hash>).

(Optional) To verify if the JMS plug-in is running, run the following script on your Linux machine:
```
curl -H "Authorization: Bearer Oracle" http://169.254.169.254/opc/v2/instance/
```
where 169.254.169.254 is the IP address of the OCI Compute Instance Metadata Service.
You should see a message similar to the following:
```

 "desiredState": "ENABLED",
 "name": "Oracle Java Management Service"
}
```

The log files are located in the /var/log/oracle-cloud-agent/plugins/oci-jms/ directory.
