System Requirements
For smaller trial or evaluation environments, please see this.
Windows Server
Version
Jubilant Server supports all versions of Windows Server in Mainstream Support by Microsoft.
For a trial, or for some other business case, Flynet may accept support on Windows Server in Extended Support. Please contact your account manager to discuss.
Windows Components
Flynet only support Jubilant installs on dedicated virtual machines and physical hardware.
The installation process will:
- Install and configure IIS (Microsoft web server).
- Install Microsoft .Net 8 hosting bundle.
- Install the Jubilant software.
Hardware
This hardware may be physical or virtual.
| Minimum | Recommended | |
|---|---|---|
| CPU Cores | 2 | 4* |
| CPU Speed | 2.5 GHz | 2.8 GHz (or higher) |
| Available Disk Space | 40 GB | 60 GB |
| RAM | 4 GB | 8 GB |
CPU Cores*
The number of CPU cores is the single most important variable for tuning performance. If each individual Jubilant server is to support a large number of concurrent sessions, the number of CPU cores is by far the most important hardware variable to increase.
maxWorkerThreads
Another significant factor for systems running more than 100 users is the IIS Machine Config setting maxWorkerThreads.
The value for this setting is very specific to the target organisations unique usage pattern. If maxWorkerThreads is set it too low, it can reduce performance. If it is set too high, it can push the CPU to 100% and slow things down.
This is why it is all always recommended to try this in a test environment first, or on one server of a load balanced set.
The aim is not to exceed 75% CPU. If the server reaches 75% CPU and it is still slow, the VM needs more virtual CPUs.
Changing this settings requires a full reboot. This will give service interruption.
Flynet recommend starting between 120 and 150 when tuning maxWorkerThreads.
Load Testing Service
Flynet offer a Load Testing service. This loads up your environment with a custom usage pattern designed to emulate real life. Settings can then be modified to see how the impact performance. Please speak with your account manager for more information.
Set-up Configuration Requirements
Any firewalls, VPNs, cloud connections between the Windows Server and the host system must have the appropriate ports opened so that Flynet Jubilant can connect.
For each host connection, the software requires:
- IP address or DNS name of the target host.
- The port of the target host.
- The emulation protocol type.
- 3270 or 3270E for Mainframe.
- 5250 for IBM System i (iSeries / as400).
- The Terminal Device Type.
- Terminal type name, or capabilities such as 24 x 8 in color, 27 x 132 in monochrome, etc.
- The codepage used by the target host.
- Whether the host connection is Telnet or Telnet over TLS.
- If TLS is to be used, any client certificates that Flynet Jubilant must provide to the host.
- If TLS is to be used, if host / server certs must be verified, we will need the full certification chain from root to issuing CA used when creating the server cert. The full hostname used in the certificate must be known.
