RE: rman script to backup on both instances in a RAC env.

Try allocating channel t3 and/or t4 to the second instance in the RAC environment. Currently we run 4 channels in our RAC backups - 2 to each instance.  

Here is the syntax we use in our backup to allocate a channel to the second instance in the RAC environment...

allocate channel node1_t4 type 'SBT_TAPE' MAXOPENFILES 16 parms="ENV=(NB_ORA_CLASS=class_name-w-hot)" connect
'account_name/password_at_connect_string';

Subject: rman script to backup on both instances in a RAC env.  

Currently my RMAN script runs on one instance of a two node RAC.    

I want to modify it to run on both instances. I have tried but no luck in allocation of channels or connection to both instance. How can I modify this please?  

Thanks.
