Hi expert,
I have to run export data pump on a production Oracle DB, I'd like to know what happen when I run this data pump export and if it produces negative effects on the DB performance.

Thanks in advance!

In general: yes. Depending on the your setup, the amount of data, the Data Pump config and so on, it might have a more or less "great" impact on the overall performance of your system.
With no other input/information, this question is quite vague to me...
