The run-time configuration settings for an application are available from within the project's properties in the IDE. Additional settings, Deployment Characteristics, for configuring an application running under enterprise server are available from Service Interfaces Properties.
Restriction: The run-time configuration settings only apply to native COBOL applications.
Some run-time behavior can be configured only by using run-time tunables, which are stored in a configuration file.
When you run the application, the IDE creates a .gcf file which includes the run-time IDE settings.
