The Data Pump Import utility provides a mechanism for transferring data objects
between Oracle databases. The utility is invoked with the following command:
Example: impdp scott/tiger DIRECTORY=dmpdir DUMPFILE=scott.dmp
You can control how Import runs by entering the 'impdp' command followed
by various parameters. To specify parameters, you use keywords:
Format: impdp KEYWORD=value or KEYWORD=(value1,value2,...,valueN)
Example: impdp scott/tiger DIRECTORY=dmpdir DUMPFILE=scott.dmp
USERID must be the first parameter on the command line.
