Connection Parameters

All of the database connection techniques let you use connection parameters. For more information on these parameters, see the Progress Startup Command and Parameter Reference.

For multiple database programming, the most important connection parameter is the Physical Database Name (–db) startup parameter, which allows you to specify multiple databases.

The Number of Databases (–h) startup parameter lets you set the number of connected databases allowed during a Progress session, up to a maximum of 240 (the default is 5).

You can group connection parameters in a text file called a parameter file. The Parameter File (–pf) connection parameter invokes the parameter file when you connect to a database. Parameter files ordinarily have .pf file extensions. For more information on parameter files, see the Progress Startup Command and Parameter Reference.
