My question seems to cross both boundaries of RMAN and Netbackup.
I need to know that when restoring with RMAN, if RMAN will be 
able to ~recover~ datafiles when the archive logs were backed up
using the bparchive binary.  My understanding is that when you
backup archive logs via an RMAN script, both Netbackup and RMAN
will have created the necessary information so that they cand find
the respective archive logs.  So my question is that with RMAN,
Will I be able to allocate a 'sbt_tape' channel during a database
recovery and then netbackup will be able to feed RMAN the needed
archive logs?

Netbackup 3.4.2
Oracle/RMAN 8.1.7.4
RMAN catalog 9.1.0.3
