In this section you will find the technical requirements for starting up the modules Portal and Tax Data Hub. You will find specific instructions for the installation in the Initial Installation.

System architecture

The system architecture is based on a three-tier architecture:

1. Client (web browser)
2. Business logic (Web Application Server)
3. Data (Database Server)

If fail-safe operation is desired, the business logic layer can be operated in a load balancer, the availability of individual server applications (health check) can be monitored and, if necessary, a database cluster can be used.

System requirements of the components

AMANA does not provide support for old software versions that are no longer maintained by the vendors. These include the operating system, the browsers, the database management system and the web application server.

Database

• Microsoft SQL Server 2017 / 2019

• Current multi-core server processor/system and at least 8 GB RAM.

• The database must be UTF-8 encoded

• Authorisation to "CREATE", "INSERT", "UPDATE", "DELETE", "ALTER" on the database, for Oracle: CONNECT + RESOURCE authorisation.

• We recommend at least 50 GB as hard disk size

• A regular backup of the database schemas is strongly recommended.Applikationsserver (Web Application Server)

It is recommended to install database server and web application server on different hardware / servers.

The following software should be available on the application server:

• Java version: JDK 17 (AMANA tests the application with Oracle's JDK 17 and Eclipse Temurin 17 from the Adoptium Working Group).
• JDBC driver for the database used
• Apache Tomcat 9.0.xx (Tomcat version 10.xx must not be used under any circumstances!)

• Current multi-core server processor/system and at least 8 GB RAM
• We recommend at least 50 GB as hard disk size

Web browser

• Current Google Chrome, Mozilla Firefox or Edge Chromium
• JavaScript must be allowed in the browser for the application
