What Is The Data Pump Import Utility? |
|
Answer» Oracle Data Pump Import utility is a standalone programs that allows you to import data objects from an Oracle dump file set into Oracle database. Oracle dump file set is written in a proprietary binary format by the Data Pump Export utility. Import can also be used to load a target database directly from a source database with no INTERVENING dump files. This allows export and import operations to RUN concurrently, MINIMIZING total elapsed time. This is KNOWN as a network import. Data Pump Import enables you to specify whether a job should move a subset of the data and metadata from the dump file set or the source database (in the case of a network import), as determined by the import mode. This is done using data filters and metadata filters, which are implemented through Import commands.
