Table import and export.

Create Data Pump Directory.

The first step in Oracle Data Pump is to create an OS level directory which will be used by Oracle for performing exports and imports. Create directory at OS level

mkdir -p /u02/export_dir

Create directory inside the database

CREATE OR REPLACE DIRECTORY export_dir AS '/u02/ranesh';

Grant Permission

GRANT READ, WRITE ON DIRECTORY /u02/ranesh TO APPS;

View the directories.

Select * from dba_directories.
