The information below applies to Terminalfour Version 8.4.0+ (unless otherwise stated) and is not relevant to older versions.

Minimum Recommended Memory (RAM)

The Terminalfour application requires a minimum allocation of 2GB RAM in order to run on your server. You'll need to ensure that your server has sufficient RAM to run other processes as well.

Server Operating System

System Version	Note
Linux (CentOS & RHEL)	We test on AL2023 which is RPM-based and includes components sourced from multiple versions of Fedora and other distributions, such as CentOS 9 Stream. We would therefore advise that similar distributions are used. Other modern Linux distributions, although not fully tested should operate correctly.
Windows Server 2025
Windows Server 2022

Database

Your database user should have full control of objects in the database/schema. It must be able to create, alter and drop all object types.

System Version	Note
MySQL 8.0^*	Check out the doc on configuring MySQL 8.0.
MS SQL 2022
MS SQL 2019
Oracle 19c	The Supported character set for Oracle is AL32UTF8

_{* Note:}_{The table engine for MySQL 8.0 databases should be: InnoDB.
In addition,}_{the collation for MySQL 8.0 should be utf8mb4}

Application

Java

The supported Java version is Oracle Java 11 OpenJDK.

We recommend and test with Temurin 11.0.23+9 from Adoptium

Application Server

The supported Application server is Tomcat 9.

The supported Proxy protocol is the Apache JServ Protocol (AJP).

Webserver

Instead of specifying specific web servers like Apache and IIS, we support the protocol/connecter to Tomcat 9. To allow for clients currently running Apache 2.2, we will support both the HTTP proxy and the AJP proxy for a number of releases to allow for an easier transition.

Support for the HTTP proxy was discontinued after Nov 1st, 2019.

We strongly advise that if you are running Linux that Apache 2.4 is configured with an AJP proxy to Tomcat 9.

If you are using Apache 2.2, then you will need to use an HTTP proxy with your Tomcat connector configured as follows:

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
               scheme="https" />

Please contact our Support team, who will be happy to advise on the best configuration to suit your technology base.
