While most Oracle 11g features are supported as of Mirror Replication Agent 15.1 ESD #1, the following features are not supported:
SecureFiles – this feature is a redesign of the implementation of large object (LOB) storage in Oracle 11g. You can mark tables containing these types of columns for replication, but the columns are not replicated.
Virtual columns – Mirror 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.
