Windows Single Session (-wss)

Use Windows Single Session (-wss) to limit a user to running only one OpenEdge client session at a time.

Operating system and syntax Windows -wss
Use with Maximum value Minimum value Single-user default Multi-user default
Client Session — — — —

This parameter applies only to a Windows GUI client. If an existing OpenEdge session is running on the machine when -wss is specified, the new session terminates and the windows of the existing session are brought forward to alert you. To avoid unnecessary processing of other parameters, use the -wss parameter first on the command line.

If more than one OpenEdge application is installed on a machine, do not use the -wss parameter because it prevents the execution of two or more applications at the same time. In addition, the -wss parameter does not recognize older versions of OpenEdge.
