Discontinuation Overview
A list of all discontinued features and announcements for future discontinuations can be found within the official WinCC OA portal. Click here!
Operating systems
The following specifications list configurations tested by ETM which are officially supported. Particularly for the new Linux distributions, this is the latest status; recommended updates to new kernel versions or patches as well as service packs for Windows are recommended.
In the following table the entries marked with "✓" indicate that the application may be used in a production environment.
"Client" refers to a remote computer which is designed for the system of a user interface (remote UI).

Operating System Specific Configurations
General
Installing patches
Consider the following notes when installing patches to your WinCC OA version:
- You have to stop WinCC OA (incl. console, project administration, PMON and log viewer) before installing a patch.
Name resolution
Working name resolution is required for WinCC OA . If the name
resolution does not work a process can be momentarily blocked. Assure that the
mapping of IP addresses to computer names and the mapping of computer names to IP
addresses works properly (this is also valid for computers in the network, where a
remote user interface is running). You can do this via an entry in the "hosts" file
(contains the mappings of IP addresses to host names) or via a DNS server that
allows forward (using a domain name to find an IP address) and reverse (using an IP
address to find a domain name) lookups. The "host" file is located in
<SystemRoot>\system32\drivers\etc
.
Firewall Settings
When using WinCC OA together with a firewall, consider that the use of a firewall restricts the communication. Check that all required ports are open.
Add the following WinCC OA programs to the firewall exceptions:
Manager Name | Executable Name | Default Port / Port Range | Notes |
---|---|---|---|
Process manager | WCCILpmon | 4999 | |
Data manager | WCCILdata | 4897 | |
Archive manager | WCCOAvalarch | 4899 - 4904 | WCCOAvalarch -num 0: 4899 WCCOAvalarch -num 1: 4900 WCCOAvalarch -num 2: 4901 WCCOAvalarch -num 3: 4902 WCCOAvalarch -num 4: 4903 WCCOAvalarch -num 5: 4904 |
Event manager | WCCILevent | 4998 | - |
Redu manager | WCCILredu | 4776 | Optional, only for redundant projects |
Dist manager | WCCILdist | 4777 | Optional, only for distributed projects |
Split manager | WCCILsplit | 4778 | Optional, only for redundant projects |
MxProxy manager | WCCILproxy | 5678 | - |
HTTP Web Server | WCCOACtrl | 80,443,8080,8079 | Windows: 80,443 Linux 8080,8079 |
VMWare
To ensure the integrity of WinCC OA systems running on VMWare, consider the following:
- WinCC OA must be properly shut down before a Virtual Machine is stopped.
- An "online backup" ("snapshot") of a Virtual Machine is not supported.
- A snapshot of a virtual machine can not be restored.
- The clock of the virtual machine must never make an unexpected jump (forward or backward) while WinCC OA is running.
- Redundant WinCC OA systems shall run on physically redundant hardware and network configurations.
- WinCC OA must not run on a virtual machine for safety critical systems.
Requirements for connecting peripheral devices
Communication with controllers or peripheral devices may require additional software components. When using OPC, compatibility of connected hardware/software with a specific operating system must be clarified with the manufacturer.
Network
Consider the following requirements for using WinCC OA network features (e.g, a distributed system):
- Specify the entry "127.0.0.1 localhost" in the hosts file for adding the localhost.
- All computers of a distributed/redundant system must have the same IPv6 state (active or inactive). A mixed mode is not supported!
Time synchronization
Configure time synchronization for the entire SCADA system. The following options are available:
- hardware-based (e.g. GPS or DCF77 radio-controlled clock)
- NTP (network time protocol)
The time adjustment must be slow enough to handle leaps. Therefore, either a third party software or a time service (e.g. W32Time under Microsoft Windows) can be used.
OpenGL Support
Set the following enviroment variable for machines with no active 3D acceleration support.
Errors will occur during the setup if the entry is not set properly and the installation process is not completed successfully.
The entry can either be specified globally for the system or before every start of the WinCC OA setup, documentation or WebView EWO.
set QT_OPENGL=angle
Windows Specific Settings
Microsoft Windows Security Updates
This product supports a Microsoft Windows operating system. Microsoft is responsible for operating system updates. Therefore, please stay informed about operating system updates directly on the following page:
https://docs.microsoft.com/en-us/security-updates/
Windows Scaling
We recommended a Windows scale factor of 100%. Any deviating settings, for example different settings on multiple monitors, can lead to significant presentation problems.
Linux Specific Settings
Restrictions - General
Consider the following restrictions when using WinCC OA under Linux:
Feature | Restrictions |

Desktop Environment
- Only the window manager GNOME is supported.
- Please note that when using the Linux desktop environment GNOME the error message "... is not responding" might appear. This happens if content is loaded that takes more than 5 seconds to finish. By pressing the "Wait" button the UI can be normally used after it has finished loading the content.
- On GNOME desktops, the 2 finger swipe gestures are not supported.
Display Server
Consider that the display server "Wayland" is currently not supported by WinCC OA .
If "Wayland" is the default display server of your distribution, select the "X11" display server manually when logging into your system or completely disable "Wayland" on your system.

- The following server versions are supported - see the table below.
- An excerpt of the server/client combinations supported by Oracle® can be found in the table below.
- Following combinations are officially tested with WinCC OA :
- Oracle® Server 19c with Oracle® Client 19c
- Only the Standard and Enterprise Editions are supported.
- Only 64bit versions of the Oracle® client are supported.
- As of the WinCC OA version 3.18 or higher, the Oracle® Client Installation is also supported under Linux. For a detailed installation manual, see the chapter Linux Client Installation with 19c.
- For the function "dbOpenRecordset" with the cursortypes 1 and 3 use the Oracle-Full Client Patch-Version 19.13 (p33155330_190000_MSWIN-x86-64).
- The VC14 support is automatically installed together with the Oracle® client software under Windows!
-
The directory of the Oracle® client oci\lib\msvc\vc14 must exist and the OS system path variable must also refer to the directory of the oraocci14.dll in the \oci\lib\msvc\vc14:
Therefore, the OS system path variable must be extended with the full path of the %ORACLE_HOME%\oci\lib\msvc\vc14 directory at the beginning of the system path.
- Consider that the usage of the Oracle® Client is only supported for operating systems officially supported by Oracle. If a different operating system is used and an Oracle Service-Request is required, the problem must be reproducible on an officially supported operating system.

Recommendations for ESXi Server and ULC UX User Interface Operation
Note the following recommendations for ESXi Server and ULC UX User Interface operation:
- Minimum memory for graphics: varies depending on graphics resolution and number of connections. Recommended for five ULC UX connections at least 512MB.
- Low latency is important
- ULC UX is rendered on the server
- There are parameters which have an influence on the performance of the ULC UX
in the web browser.
- Bandwidth
- Latency
- Dynamic panel content
- CPU performance of the web server
- Available memory on the web server
Because the performance and the possible ULC UX connections to one web server are highly dependent on the panels and the scripting inside the panels, we cannot guarantee any specific number of possible connections. This will be highly customer panel dependent and will need to be tested with the panels used in the customer project to determine the possible ULC UX connections.
