Oracle Data Pump New Featurs

1.The ability to specify the maximum number of threads of active execution operating on behalf of the Data Pump job. This enables you to adjust resource consumption versus elapsed time. See PARALLEL for information about using this parameter in export. See PARALLEL for information about using this parameter in import. (This feature is available only in the Enterprise Edition of Oracle Database 10g.)

2.The ability to restart Data Pump jobs. See START_JOB for information about restarting export jobs. See START_JOB for information about restarting import jobs.

3.The ability to detach from and reattach to long-running jobs without affecting the job itself. This allows DBAs and other operations personnel to monitor jobs from multiple locations. The Data Pump Export and Import utilities can be attached to only one job at a time; however, you can have multiple clients or jobs running at one time. (If you are using the Data Pump API, the restriction on attaching to only one job at a time does not apply.) You can also have multiple clients attached to the same job. See ATTACH for information about using this parameter in export. See ATTACH for information about using this parameter in import.

4.Support for export and import operations over the network, in which the source of each operation is a remote instance. See NETWORK_LINK for information about using this parameter in export. See NETWORK_LINK for information about using this parameter in import.

5.The ability, in an import job, to change the name of the source datafile to a different name in all DDL statements where the source datafile is referenced. See REMAP_DATAFILE.

6.Enhanced support for remapping tablespaces during an import operation. See REMAP_TABLESPACE.

7.Support for filtering the metadata that is exported and imported, based upon objects and object types. For information about filtering metadata during an export operation, see INCLUDE and EXCLUDE. For information about filtering metadata during an import operation, see INCLUDE and EXCLUDE.

8. Support for an interactive-command mode that allows monitoring of and interaction with ongoing jobs. See Commands Available in Export's Interactive-Command Mode and Commands Available in Import's Interactive-Command Mode.

9.The ability to estimate how much space an export job would consume, without actually performing the export. See ESTIMATE_ONLY.

10. The ability to specify the version of database objects to be moved. In export jobs, VERSION applies to the version of the database objects to be exported. See VERSION for more information about using this parameter in export.

In import jobs, VERSION applies only to operations over the network. This means that VERSION applies to the version of database objects to be extracted from the source database. See VERSION for more information about using this parameter in import.

11.Most Data Pump export and import operations occur on the Oracle database server. (This contrasts with original export and import, which were primarily client-based.) See Default Locations for Dump, Log, and SQL Files for information about some of the implications of server-based operations.
