If a fail-safe operation is required, the business logic layer (business 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. The implementation of a Single-Sign-On mechanism (SSO) is also possible on the application server. More detailed configuration information is not included in this document and can be provided separately.
Connection to the other systems is provided via the client or must be triggered by the client.
A data import, e.g. import of IFRS values from the accounting or consolidation system, can be carried out either via the client by uploading an XLSX/CSV file or via the server, i.e. through a direct connection between the server and the accounting or consolidation system.
The electronic tax return is sent to the tax authority via a separate transfer client, which can be installed in a demilitarized zone of the computer centre (access to the Internet is required).

AMANA does not provide support for older software versions that are no longer maintained by the manufacturer. This may concern the operating system, web browser, DBMS and WAS, among other things.Examples for not supported software versions are Windows XP, Internet Explorer 8 and, since January 2016, Internet Explorer 10.
Database
- Microsoft SQL server 2017 / 2018 / 2019 and Oracle 19c (19.3) or 21c. AMANA recommends using Microsoft SQL servers. This is particularly useful if you also use, or are planning to use, other AMANA products, e.g. Tax Balance.2019. Since 2023 Oracle isn't supported for new installations of Income Taxes any more.
- Current multiple-core server processor/system (at least 2 GHz clock speed), for processor-intensive reports at least 2 cores, for larger installations (from approx. 100 companies) preferably 4 cores (also for VMs)
- At least 8 GB RAM for the server. For larger installations (from approx. 100 companies) preferably 16 GB RAM for the database server
- The database must be UTF-8 coded
- Authorization to "CREATE", "INSERT“, "UPDATE“, "DELETE“ and "ALTER“ on the database, for Oracle: CONNECT + RESSOURCE authorization
- The required database memory depends to a large degree on company size and user behaviour. In the latter case, it is particularly relevant how often file attachments or documents (Excel, csv, ...) are stored (sometimes these files are stored in an external folder). As a rough guide, we recommend approx. 500 MB memory per 10 companies and period.
- A regular backup of the database schemas is strongly recommended.
...
We recommend that the database server and web application server are installed on different hardware / servers. Virtual servers are supported (e.g. via VMWare, VirtualBox, etc.).
- Java version:
- since GTC version 22.09.00: JDK 17 JDK 17 (AMANA is testing the GTC with Oracle's JDK 17 and Eclipse Temurin 17 from the Adoptium Working Group).up to GTC version 22.00.xx: JDK 8 (Advice on supported JDKs)
- JDBC driver for the database used
- Apache Tomcat 9.0.xx (Tomcat 10.xx is not allowed to be used under any circumstances!)
