Rules of Precedence for Parameter Specification

You can specify the two named subsystem parameters, ConnectionSubsystem and DataHandlingSubsystem, as either business service user properties or as run-time arguments. If you specify the parameters in both locations, the business service user property takes precedence over the run-time arguments.

NOTE:  For additional information on named subsystems, see Siebel System Administration Guide.

You specify every other parameter in one of the two named subsystems or as run-time arguments. Siebel EAI looks for the parameter in the ConnectionSubsystem or the DataHandlingSubsystem, depending on which parameter it is. If you specified the appropriate named subsystem, Siebel EAI will always look for the parameter there.

If you do not specify the parameter in this named subsystem, even if you specified it as a run-time argument, the run-time specification will be ignored. Siebel EAI looks for the parameter in a run-time specification only if no appropriate named subsystem is specified.
