Todd is correct on using the input distribution to move and rename your file.
It may be better to create a schedule that operates once per day, then configure the retries to retry until the next iteration of the schedule, or you will end up with a number of failed processes, as the retries expire every 5 minutes.
In the next point release of Data Pump, there will be a "Retry Indefinitely" setting, so you can get much closer to a trigger type approach.
There is no exact equivalent of the file trigger settings as in MDP6, as this methodology brings many problems with it, especially when getting files over slow connections such as WANs and FTP. What can happen is that the trigger fires, but the file is not fully written.
