12c Database Datapump Enhancements

12c Database Datapump Enhancements


Below are some of enhancements for Datapump

 1)      In 12c You can use the DISABLE_ARCHIVE_LOGGING Parameter
               to specify that objects be loaded with nologging of redo.
            Example:

    Schema level

 2)      You can have timestamp printed for every object that is imported. Also during export you can use same.

Example:

     During export:
