Last updated on MARCH 27, 2014

Applies to:

Oracle Optimized Warehouse - Version: 10.2.2 and later   [Release: and later ]
Information in this document applies to any platform.
This is applicable to releases prior to 11g.

Symptoms

The source has a  noncompressed table. When a datapump import of the same is done into a target with a pre-created compressed table, using the network_link, it is seen that the data is not compressed.

In the absence of the network_link option, the data after IMPDP is seen to be compressed in the target.
