Agent Prerequisites

Note

Using the Prerequisite Wizard for Setting Up Oracle Cloud Infrastructure for Fleets and Using Oracle Management Agent Software Installer from the Download Oracle Management Agent Software Installer with Requisite Software section will address the prerequisites and recommendations listed in this topic.

The following are prerequisites for agent installation:

You have read Perform Prerequisites for Deploying Management Agents and ensured that your host meets the prerequisites, including the requirement for JDK 8.
You have completed the policy setup steps for the installation script to run successfully.
You have ensured that the clock on your host is synchronized with the OCI platform. You'll be unable to install a management agent if your host's clock is skewed more than five minutes from the OCI platform. For more information, see Maximum Allowed Client Clock Skew.

Recommendations:

Use JDK instead of JRE for setting up Management Agent Cloud Service (MACS). Advanced features don't work if the management agent is running on the JRE instead of the JDK. This is because advanced features use the tools.jar, which is available only on the JDK and not on the JRE.
Use the latest Oracle JDK 8 release for setting up MACS. Advanced Features won't work if Management Agents are running on JDK 8 releases earlier than JDK 8 update 361 (JDK 1.8.0_361).
Set up the management agent with a Java installation that is independent of system Java. For example, while installing the management agent, set JAVA_HOME to JDK 8 that is not managed by the operating system's package management system.
Update the Java runtime used by the management agents by following the instructions detailed in the Using Java with Management Agent section to ensure the management agents continue working.
