Prerequisite configurations for Discover Replay Server

The Discover Replay Server contains a web application component named DOMDiffServer. The Discover Replay Server isntallation deploys DOMDiffServer web application and Apache Tomcat version 10.1.16 (the new Apache Tomcat version is applicable from version 12.1.9 and above).

Before you begin

Java 11 is a prerequisite for Apache Tomcat webserver runtime. Before installing Discover Replay Server, you must configure JAVA_HOME.

About this task

Note: If you had an earlier version of Apache Tomcat, it was using JRE_HOME environment variable. If you have already configured JRE_HOME, you must remove that variable. Having both JRE_HOME and JAVA_HOME will cause issues with Apache Tomcat's start.bat and shutdown.bat.

To configure JAVA_HOME, complete the following steps:

Procedure

Download JDK version 11.0.16.
Extract the contents of the ZIP file to the required location and folder.
For the JAVA_HOME environment variable, point it to the extracted location and folder.
