Table Marked As Unsupported After Making A Rowid Column Unused (Doc ID 1931121.1)

Last updated on MAY 07, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.3 and later
Information in this document applies to any platform.

Symptoms

 When a rowid column is made unused the table becomes unsupported by Streams as per the following output

SQL> select * from dba_streams_unsupported;

OWNER TABLE_NAME REASON AUT
------------------------------ ------------------------------ --------------------------------------- ---
OXYGEN SILO unsupported column exists NO


Changes

For the columns which are not supported by Streams gets entered into the view DBA_STREAMS_UNSUPPORTED.
But when that unsupported column we make as UNUSED column then it should not be shown into DBA_STREAMS_UNSUPPORTED view, as UNUSED columns are being supported by streams.
