Our daily DTS data pumps normally run without errors, but there are a lot of messages written to the log file. If errors do occur, the messages don't help much and we have to investigate the data file in any case. It seems that we can probably reduce those messages to indicate only success or failure by using a tailored multiphase data pump.
Please comment on the differences between the default and a multiphase data pump in terms of what the default actions are. What might be involved in creating a less verbose data pump?
