The N-Squared JSLEE is officially supported on the following:
Red Hat based systems:
- Red Hat Enterprise 7.4 and later.
- Red Hat Enterprise 8 (Installation Details)
Debian based systems:
- Ubuntu 18.04 LTS
- Ubuntu 20.04 LTS
In practice, the JSLEE will run on any system that runs Java 11 or later, particularly any Debian or Red Hat based distribution (including CentOS and Oracle Enterprise Linux) with appropriate adjustments to these installation instructions.
Minimum Server Requirements
The JSLEE is a powerful horizontally and vertically scalable charging system yet can run on lightly resourced virtual machines.
A minimum server environment would consist of:
- Disk space of 5Gb above the minimum installation required for the Linux distribution being installed.
- At least 4Gb of RAM.
- At least two 2.4GHz vCPU, or equivalent.
- A Java 11 (or higher) JRE.
In practice, a virtual machine with 30Gb of disk, 4Gb of RAM and two 2.4GHz vCPU will provide the necessary resources to run a lightly loaded JSLEE service.
