The name and location of the connection configuration file is specified at the setting ITPDMINIFILE= in the ITP configuration file. You can set or change this setting with the ITP Administration Program. The value of this setting is the name of a file. The connection configuration file is called the DataManager ini file or Dm.ini file. You can change the contents of the Dm.ini file with the ITP Administration Program by selecting Connection configuration.
