Exalogic Exachk Diagnostic Information and Suggested Actions (Doc ID 1463157.1)

Last updated on MARCH 12, 2021

Applies to:

Oracle Exalogic Elastic Cloud Software - Version 1.0.0.2.0 and later
Exalogic Elastic Cloud X5-2 Hardware
Linux x86-64
Oracle Solaris on x86-64 (64-bit)

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.
