Licensing and AVEVA Single Sign-On components

The MES installation software also includes the following components:

• The License Server and Manager. The licensing components must be installed so that MES product licenses can be added to the system.

• AVEVA Single Sign-On. The AVEVA Single Sign-On service provides secure access to MES when using MES Web Portal or the MES Web API in custom applications.

It is possible that these components have already been installed in the system. However, if they are not installed, then they can be selected during the MES installation using the custom installation feature.

In addition to these two licensing components, there is also a Licensing API that is automatically installed when the MES Middleware or Web Portal components are installed. The licensing API can also be installed during an MES command line (silent) installation by specifying LicAPI64 in the response file.
