Datapump Performance Issue With Content=Metadata_only

(Doc ID 1290574.1)

Last updated on NOVEMBER 28, 2016

Applies to:

Oracle Server - Enterprise Edition - Version: to - Release: 10.2 to 11.2
Information in this document applies to any platform.


A Data Pump content=metadata_only Export on a database with many partitions takes much longer than expected (i.e. 1.5 hours).

Typical partition counts:
select count(*) from dba_tab_partitions; 10,000+
select count(*) from dba_tab_subpartitions; 50,000+

Expect the export to complete in minutes, given no actual table data is being exported.
