What are the prerequisites before Import Data Pump using impdp?

Before performing an impdp operation (Import Data Pump), you should make sure that you have the following prerequisites:

1. Sufficient privileges: You should have the necessary privileges to perform the impdp operation. This typically includes the IMP_FULL_DATABASE system privilege, which allows you to perform a full database import.
2. Sufficient disk space: You should have enough disk space on the server to store the imported data.
3. Access to the dump file: You should have access to the dump file that you want to import. This file should be located in a directory that is accessible by the Oracle database server.
4. Compatibility: The dump file should be compatible with the version of the Oracle database that you are importing it into. You can check the compatibility by running the impdp utility with the SHOW=Y parameter.
5. Network connectivity: If you are importing data from a remote server, you should have network connectivity between the source and target servers.
6. Proper configuration: You should ensure that the database and the database server are properly configured and running before performing the impdp operation.
7. Storage configuration: You should ensure that the storage configuration on the target database is appropriate for the data that you are importing.
