About parameter files

A parameter file is an operating system file that contains one or more startup parameters. The primary reason to use a parameter file is to avoid typing commands each time you want to start OpenEdge. Instead of repeatedly typing a series of parameters and other arguments, type them once and place them in a parameter file. You can also use a parameter file to maintain the startup parameters for a particular database, group of users, or system configuration. A parameter file has a .pf extension.

Every OpenEdge executable invokes a parameter file named startup.pf by default. This file is located in the DLC directory. It must exist for OpenEdge to execute properly. You can modify startup.pf to add parameter definitions. You can also create one or more additional parameter files and direct OpenEdge to invoke them after it invokes startup.pf.
