Metalink note 388424.1 C.The Skip tablespace section should list all tablespaces from the production target that are NOT required in the duplicate clone database. The Temp tablespace is not required here as RMAN does not backup this tablespace. Also note that any tablespaces listed here that contain LOBS may cause the duplicate to fail, due to dropping the LOBS. If possible include these tablespaces as opposed to skipping them regards Hrishy -- //www.freelists.org/webpage/oracle-l
