The recommended method for setting environment variables is in the global appx.env file, which is in the APPXPATH directory (APPXPATH/appx.env).
Benefits
· Convenient if you have a mix of Telnet and APPX/Client users
· All variables are in a single file
Per-user appx.env is not available for APPX/Client users and it is only useful in “shared disk” configurations on Windows, and for Unix Telnet access to APPX. The variables should be placed in either the ~/appx.env or C:\appx.env files.
Benefits
· Allows you to set variables on a per-user basis
Disadvantages
· Overrides any operating system settings; also overrides any global appx.env settings
· Not applicable for APPX/Client
