How License Server Details are Configured

The license server configuration for a workstation is set using the environment variable AVEVA_LICENSE_SERVER_LIST. An environment variable is used as it permits you to configure applications to use different license servers by overriding the default workstation setting in a batch file.

License server host details are configured in the following format:

<port>@<hostname>

Where <port> is the port number used by the license server and <hostname> is the hostname or IP address of the host on which the license server runs. A typical entry would look like this:

4545@licserver

Multiple AVEVA Licensing Systems can be configured by separating the details of each license server host with a semi-colon character (';'):

<port1>@<hostname1>;<port2>@<hostname2>;<port3>@<hostname3>

A typical multiple server entry would look like this:

4545@licserver1;4545@licserver2;4545@licserver3

The format is also used when configuring a workstation for use with a three-redundant-server licensing system. It is necessary to include details of all three license servers in the redundant-server array so that the workstation can locate a backup license server if the primary license server is not active. Although the license servers can be specified in any order, it is strongly recommended that for optimum performance the license servers are specified in order of primary server, secondary server, then finally tertiary server.
