This section describes the technical requirements for launching the GlobalTaxCenter (GTC) software, including all of its modules. Full instructions on how to install it are provided in the installation instructions/wiki/spaces/GTCE22/pages/9797820.

System architecture

The GTC is a web-based application. It serves the group tax department as a tax portal and offers the possibility to automate process steps by connecting to other systems, thus reducing manual activities.

• Microsoft SQL server 2017 / 2018 / 2019 or Oracle 12c (12.2) and 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.
• 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.
