DTM ODBC manager supports next command line switches:

-is<filename> - import DSN definitions from the file as a system data sources

-iu<filename> - import DSN definitions from the file as a user data sources

-es<filename> - export all system DSNs definitions to the file

-eu<filename> - export all user DSNs definitions to the file

-s<system> - remote system name

Examples:
-esd:\dsndef_S2.dsn -sSERVER2
runs export system DSNs from SERVER2 to local file d:\dsndef_S2.dsn

-eu"d:\dsn definitions\user.dsn"
runs export local user DSNs to "d:\dsn definitions\user.dsn" file

'e' or 'i' specified parameter switches the program to console mode. The console mode is a mode when the program doesn't open any dialogs and doesn't need any interference from the user. This mode enables you to integrate the product with the Windows task schedule system as well as to execute packages prepared beforehand according to the schedule.
