Logical Standby table not supported 11.2.0.1

Question

I have a table with CLOB in primary and runs the SQL to determine which tables are unsupported.
They, nor I, can see why this table is unsupported. Please let me know what I am missing.
Are there additional steps to see why?
Please also see the DDL for the table at the end.

Answer 1

Hi I was able to find the following answer. Thanks
"Logical standby has never supported tables that only contain LOBs. We require some scalar column that can be used for row identification during update and delete processing.
There is some discussion of row identification issues in section 4.1.2 of Oracle Data Guard Concepts and Administration. "
http://docs.oracle.com/cd/E11882_01/server.112/e25608/create_ls.htm#i77026
"If there is no primary key and no nonnull unique constraint/index, then all columns of bounded size are logged as part of the UPDATE statement to identify the modified row. All columns are logged except the following: LONG, LOB, LONG RAW, object type, and collections."
So you see with only a LOB column it cannot identify the row. You need a primary key or at least some columns that can uniquely identify the row. The one LOB column is no logged with the supplemental logging.
So it is not supported.
