PROPATH and other standard OpenEdge environment variables
When you install the WebSpeed Transaction Server, the installation process sets PROPATH for you in the ubroker.properties file. PROPATH initially includes a number of subdirectories in your installation directory. In addition, the PROPATH includes a dot ( . ) directory reference. When the agent sees the dot, the process substitutes the name of its current working directory. For example, the agents resolve the dot to their broker's default directory, which is the working directory.
You can modify this and other environment variable settings in the OpenEdge shell scripts installed on UNIX. You can override installed PROPATH settings using the PROPATH property in the properties file (ubroker.properties).
