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

If you do try and parallelize the backup across multiple instances -- then
all instances that participated in the backup must also be available to
perform recovery?

 Try allocating channel t3 and/or t4 to the second instance in the RAC

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@connect_string';

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.
