Oracle 11g is supported as of Replication Agent 15.1 ESD #3. These Oracle 11g features are not supported:
SecureFiles – this feature is a redesign of the implementation of large object (LOB) storage in Oracle 11g. Tables containing these types of columns can be marked using the force option, but the LOB columns are not replicated.
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. Tables with virtual columns can be marked using the force option of the pdb_setreptable command, but these columns are not replicated.
Encrypted tablespace – objects (tables and columns) on encrypted tablespace cannot be marked for replication.
Encrypted columns – tables containing encrypted columns can be marked for replication using the force option of the pdb_setreptable command, but these columns are not replicated.
