ORA-01041 error when duplicating database to new host

Question

I'm using RHEL 5 with Oracle 11g and I'm testing data guard.
I am trying to setup data guard by following this link:
http://www.databasejournal.com/features/oracle/article.php/3816751/Oracle-11g-Data-Guard-Building-a-Physical-Standby-Database.htm
I use the following command:
[oracle@linux-test ~]$ rman target sys/oracle auxiliary sys/oracle@stdby

SET fal_client='stdby'
SET fal_server='orcl'
SET standby_file_management='AUTO'
SET log_archive_config='dg_config=(orcl,stdby)'

When it's starting datafile copy, I get this error:
channel d1: starting datafile copy

I have googled it but I still have no solution yet.
Any idea please?

Use a 'Try and Error' strategy, remove the manual channel allocations from the script, these are not mandatory. Let RMAN automatically allocate channels.
