Purpose
Exachk for Exalogic is a health-check tool that is designed to audit important configuration settings within an Oracle Exalogic machine. This reference document describes the benefit of the check, the risk, if a particular health-check fails, and the steps to resolve a failed health check, for each of the health checks that Exachk.
Scope
This document is intended for anyone planning to use and run Exachk on Oracle Exalogic Engineered Machine.
