CDC for Oracle(version 11.4) does not work with longer identifiers than 30 bytes.

Use cases for the system: updates source data.
System: continous mirroring

・prepare oracle12c with definition 30 bytes over identifier.
・and implements CDC for oracle.
・update some data on source database.
・check to flat file.
 There is nothing primary key.


We already have source database for Oracle10g with Japanese identifiers, and currently utilize CDC 10.2.
It has a multi-byte character-set, and currently identifier is defined a full-character.

However, we have a migration plan to Oracle12c with UTF8, and doing this will extend identifier size by 1.5 times.(Japanese character with shift-jis needs 2 bytes, on the other hands with UTF-8 needs 3 bytes.)
We have decided to utilize CDC v11.4, because your sales agent proposed us this product.

But CDC for Oracle does not work only when updates.
This identifier limit should be extended to 31-128 bytes.
