I already have the commands to create the controlfile.

The problem is that a controlfile cannot be created without the datafiles being present.

I needed the controlfile to restore the datafiles. catch-22.

The files *can* be restored via RMAN DUPLICATE, but the recovery fails.

The database was opened with resetlogs on the 32 bit platform, just to prove it could be done. Converting the word size is not as simple as ML Note 62290.1 intimates.

The instruction in ML for Bug 2555795 allowed recompiling stored code.

As the RMAN DUPLICATE command can restore the files, clealy it can be done manually. Successfully restoring a 64 bit database to a 32 bit server may require some magic with dbms_backup_restore.

You could also use the rman resore controlfile from

Doesn't work. I think I already documented that in this thread.

Thanks for trying to help.
