A Web Application Server may be installed on a separate machine and configured for fault tolerance.
Supported web application servers include:
- Apache Tomcat version 8.5.5 or later.
- Oracle WebLogic version 12c R2 (12.2.1) or later.
You must know the port number on which your web application server receives incoming requests and the path to the directory where your web application server stores web application .war files. (This directory is sometimes called webapps.)
Additionally, you must allow the necessary system accounts permission to run the Web application Server. For more information, see Directory and Account Permissions.
