Thank you (Michael and Richard). Here is what the RMAN Advanced User's Guide says - "It also supports a transportable database feature, which can be used to recreate an entire database from one platform on another platform as long as the platforms have the same endian order." I think my only other ption is what Michael mentioned: precreate a shell database then transport user tablespaces one by one from source to target.
