https://www.veritas.com/support/en_US/article.HOWTO64200

Make sure you have installed Oracle with the same user as used on the original source client machine
Install NetBackup Client and Oracle agent
Patch if needed
Touch the file on the master server: => /usr/openv/netbackup/db/altnames/No.Restrictions
Browse the Oracle backups by running /usr/openv/netbackup/bin/bplist -S <master server> - C <Oracle source client name> -t 4 -l -R /
- => Make sure you can browse the backups

Restore the control file (in NOMOUNT mode) - See exact steps for this procedure in technote HOWTO63971

   => SQL> STARTUP NOMOUNT pfile='/u01/xxx.ora'
  rman nocatalog
   => RMAN> connect target 
   => RMAN> SET DBID=XXXXXX
      RMAN> restore controlfile from '/tmp/xxx';

Restore the database (in MOUNT mode)

 RMAN> mount database
 

 8. Restore the database using the script in /usr/openv/netbackup/ext/db_ext/oracle/samples/rman/database_restore.sh
