Connection parameters
Connection parameters control how you connect to databases and are a subset of the OpenEdge startup parameters. All of the database connection techniques provide a way for you to specify connection parameters.
You can use a parameter file to specify connection parameters with any of the connection techniques. A parameter file is an operating system file that contains one or more startup parameters. A parameter file has a .pf extension. Use the Parameter File (-pf) startup parameter to invoke a parameter file.
Parameter files are an important factor in developing database connection strategies for multi-database applications. For example, you can use parameter files to maintain the startup parameters for a particular database, group of users, or system configuration.
For more information about startup parameters and parameter files, see OpenEdge Deployment: Startup Command and Parameter Reference.
