Preparing to Install

Requirements

For detailed information about the requirements for running IG, see Requirements. The following software is required:

Oracle JDK 11 or later versions, or OpenJDK 11 or later versions.

Configuring the Network

Configure the network to route network traffic to IG and the sample application. The examples in the guide assume that:

IG is reachable on http://openig.example.com:8080.
The sample application is reachable on http://app.example.com:8081/home.
AM is reachable on http://openam.example.com:8088/openam.

Before you try out the examples, configure the network to include the hosts.

Configure the Network

Add the following additional entry to your /etc/hosts file on UNIX systems or %SystemRoot%\system32\drivers\etc\hosts on Windows:
```
127.0.0.1  localhost openig.example.com app.example.com openam.example.com
```
For more information about host files, see the Wikipedia entry, Hosts (file).
