Virtual columns – Replication Agent supports the replication of tables containing computed (or virtual) columns in Oracle 11g. However, the replication of individual computed columns is not supported. You can mark virtual columns for replication using the force option, but these columns are not replicated.
Encrypted tablespaces – You cannot mark encrypted tables and columns in encrypted tables for replication.
Encrypted columns – you can mark tables containing encrypted columns for replication using the force option, but these columns are not replicated.
