Function and operation of the Automatic Update Service

The Automatic Update Service is used to configure the automatic update of Axxon PSIM and vertical solutions in a distributed network. The service is installed in addition to the main product and works independently of it.

Service components

There is the update server (installation type is Server (Administrator's workplace)) that distributes the version for the update, and the client (installation type is Client (Workstations)) that are dependent servers that receive the version from the update server and install it. In addition, the Update manager program is installed to manage the updates together with the update server. Thus, you need to select the distributor server and install the Server (Administrator's workplace) on it, and install the Client (Workstations) on the servers that need to be automatically updated. For details, see Installing the Update Service.

After installation, you need to configure the update server and the clients—see Configuring the update server (distributor) in the Update manager and Configuring the client (receiver).

Principle of operation

Once configured, it works as follows:

1. The clients connect to the update server.

2. The update server contains a list of available updates.

3. The automatic update parameters for the clients are configured on the update server using the Update manager program.

4. At some point in time (depending on the settings in the Update manager), the client receives an update task in the form of an installation package. This package updates Axxon PSIM on the client. For more details, see Configuring the client (receiver).

Requirements for user permissions in Windows OS

The update server is installed in Windows OS as a service, so you must install it with Administrator privileges in Windows OS.

Note that the automatic update on the client starts a software installation that can require Administrator privileges in Windows OS.

The behavior is as follows:

1. When updating as a standard user with UAC enabled: during installation there is a start request requiring an Administrator password.
2. When updating as an Administrator with UAC enabled: during installation there is an installation permission request.
3. When updating with UAC disabled: there aren't any additional requests.

Collecting information about the Automatic Update Service in the Support.exe utility

If necessary, you can collect information about the operation of the Automatic Update Service in The utility for collecting configuration data on servers and RWS for the Technical Support. The generated archive contains the UpdateService folder containing files of logs, settings, and possible failures in the operation of the client and update server.
