Compression Is Not Working On Bulk Loads For Wide Tables Starting With 12.1.0.2.160119 (Doc ID 2263452.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 12.1.0.1 to 12.2.0.1 [Release 12.1 to 12.2]
Information in this document applies to any platform.

Symptoms

Compression is not working for wide tables and table containing chained rows anymore on bulk loads or direct loads after applying a patch greater than
12.1.0.2.160119 DBBP. This can lead to side effects like:
- additional space need to be considered for such tables (double space) when reorganizing
- compression can still be used but only with insert/update/delete and avoiding bulk loads

If such tables need to be compressed then what are the options to do this?
We identified up to now that this can be made offline only using exp/imp or line by line insert.

This can lead to problems with SAP application tables.
