LOB Segment does not release space in an MVIEW after upgrade to 12c (Doc ID 2107167.1)

Last updated on MARCH 30, 2016

Applies to:

Oracle Database - Enterprise Edition - Version 12.1.0.2 and later
Information in this document applies to any platform.

Symptoms

Materialized view which contains a LOB column that gets a complete refresh every night seems to have LOB storage growing at an alarming rate. It appears as if each attempt at refreshing the MV, the lob takes more storage and does not relinquish any.

Changes

 Upgraded to 12c
