Use the Import utility of the new database to import the objects exported from the current database. Stops the current job either immediately or after an orderly shutdown, and exits Import. Both of the following situations would result in an error because the encryption attribute for the EMP column in the source table would not match the encryption attribute for the EMP column in the target table:.

This directory object is automatically created at database creation or when the database dictionary is upgraded. Enables you to specify the Import parameters directly on the command line. You are not given direct access to those files outside of the Oracle database unless you have the appropriate operating system privileges.

Exporting and Importing Between Different Database Releases

In such a case, the worker process becomes a parallel execution coordinator. This provides improved flexibility for transforming the metadata at import time. For export and import operations, the parallelism setting specified with the PARALLEL parameter should be less than or equal to the number of dump files in the dump file set.

The mapping may not be percent complete, because there are certain schema references that Import is not capable of finding.
