Oracle 10g, 11g, and 12c XMLTYPE Restrictions

Replication Agent supports the replication of XMLTYPE columns and tables if they are stored as CLOB or XML data. Replication Agent does not support the replication of XMLTYPE data in object-relational XML storage or binary XML storage.

Replication Agent supports the replication of XMLTYPE columns from an Oracle primary database to an Oracle or SAP Adaptive Server Enterprise replicate database, but no other platforms are supported. Replication Agent replicates XMLTYPE tables only from an Oracle primary database to an Oracle replicate database.

Note: The XMLTYPE datatype is supported only for replication to Oracle 10g replicate databases from Oracle 10g, 11g, and 12c primary databases.
