From the UI you can use TRTPROP (All > Development > Utilities > Verifications > Database > Properties on a standard menu). This function will derive either Oracle or SQL Server and show the correct screen for you. Then you will see the Machine and Instance name there. 

If you need it from within the 4GL code you can call ORDSYS.GET_SQL_SERVER_INSTANCE_NAME()
