Configure FMS multiuser support

Configure FMS multiuser support On Windows systems, the pipe connection to the FMS client cache (FCC) uses a single value by default, allowing only one user to connect to the FCC per Windows workstation. If you want to enable multiple users to start FCC client applications on the same machine at the same time, set the FMS_WINDOWS_MULTIUSER environment variable to true. A multiuser situation occurs, for example, when multiple users employ remote access applications such as Citrix or Remote Desktop to access Teamcenter applications on a common Windows machine. FCC separation is achieved because the environment variable setting causes the pipe names used for the client-to-FCC communication to include the user ID, ensuring that each user connects with a unique pipe to the appropriate FCC. If the FMS_WINDOWS_MULTIUSER variable is set to true, user names should not end in numerals. Names ending in numerals confuse the automated pipe name generation. For example, the pipe named {RootPipeName}_User121 could be the first data pipe belonging to User12, or the 21st pipe belonging to User1. Use the following steps to configure FMS running on a Windows system to accept multiple users: Procedure In the system environment (System Properties>Advanced>Environment Variables>System Variables), set the FMS_WINDOWS_MULTIUSER environment variable to true. To set a global environment variable, local administration privileges are required. To propagate this setting to all users and applications, reboot the system. Siemens Digital Industries Software customer support will assist in working through issues. Any issues that are Siemens Digital Industries Software code related can be addressed as problem reports. Issues arising from operating system or third party tools must be addressed with that vendor.
