While most Oracle 11g features are supported as of Replication Agent 15.1 ESD #3, the following features are not supported:
SecureFile – 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 – 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 tables with virtual columns for replication using the force option, but the virtual columns will not be replicated.
Encrypted tablespaces – You cannot mark tables or columns belonging to an encrypted tablespace for replication. If the tablespace that a marked table or marked column belongs to is subsequently updated so that the tablespace becomes encrypted, Replication Agent will automatically unmark the table or column.
If the first table modified by a transaction is stored in an encrypted tablespace and subsequent table modifications for the same transaction occur against non-encrypted tables, Replication Agent neither recognizes nor replicates the subsequent non-encrypted operations.This is an issue only when the first operation is for an encrypted table. If the operation against the encrypted table is not the first, only the encrypted operation is ignored. All prior and subsequent non-encrypted operations are processed.
Encrypted columns – you can mark tables containing encrypted columns for replication using the force option, but these columns are not replicated.
XML – Oracle 11g XML types are not supported.
