Explanation:

2.4.4.6Oracle Data Pump No Logging Option for Import

The newTRANSFORMOptionDISABLE_ARCHIVE_LOGGING, to theimpdpCommand line causes Oracle data Pump to disable redo logging when loading Data into tables and when creating indexes. It also adds the same option as part of the PL/SQLDBMS_DATAPUMPPackage. With redo logging disabled, the disk space required for redo logs during a Oracle Data Pump import is smaller. However, to ensure recovery from media failure, the DBA should does an RMAN backup after the import completes.

Even with this parameter specified, there are still redo logging for other operations of Oracle Data Pump.This includes allCREATE andALTERstatements, exceptCREATE INDEX, and all operations against the master table used by Oracle Data Pump during the import.
