Choose Utilities > Editor for Parameter Files to view a complete list of startup parameters, fill in the desired values, and write out a .pf file (rather than typing in the parameter file with an ordinary text editor). When you choose this option, the Data Dictionary prompts you for the name of the .pf file to edit or create. After you specify the filename, the Edit Parameter File (param.pf) dialog box shown in the following figure appears.
