Restoring a 32Bit (with 32 Bit Oracle Binaries) RMAN backup on 64Bit Operating System (with 64 Bit Oracle Binaries) - same Operating System Platform !
On a given platform, backups are interchangeable between 32 and 64 bit versions of Oracle.
However, simply restoring a backup that you took on a 32-bit system, onto a 64-bit system,
is not sufficient to migrate your database from 32-bit to 64-bit.
You must also follow all of our other migration procedures, such as re-compiling your pl/sql.
Same goes for a backup taken on 64-bit Oracle and restoring with 32-bit Oracle.
