Oracle 8 rman script in 10G environment

 I have used this Oracle 8 rman backup script for years and now I am working in a 10g environment.  If someone could please review and let me know what has changed in 10G and is no longer needed in this script.  If the syntax has changed I would also appreciate feedback on the newer corrected syntax as well.

I believe channel allocation is automated now and wouldn't need to allocate channels correct?

Also, I believe that by setting ---- configure controlfile autobackup on; --- I can also skip backing up the controlfile correct?

resync catalog;

  set maxcorrupt for datafile 1 to 0;
