I used to think that way too Mladen. A colleague of mine says that from 11g
on you can do restores/recovers from multiple nodes at the same time - ie,
the restore work can be divided simultaneously between multiple nodes. I
have not heard of this feature. I was wondering may be they keep backup
files in a shared location (ASM? some shared filesystem oracle can read?)
and do restores?
I came across this
<http://oracleabout.blogspot.com/2013/01/restore-database-rac.html> online,
and thought maybe this is a new feature I didnt know.

I am trying to do a restore of a db in a cluster. It looks like we can
restore from multiple nodes/instances in a RAC from 11g on. I would think
that the backup files would need to be visible from all nodes in the
cluster. Does anyone have the setup and steps that they can share. thanks.
TIA, OL
What do you mean by "restore from multiple nodes/instances"? What I
usually restore from is backup, not a node or an instance.
Second, you cannot restore backup to a RAC database. You can only restore
backup to a single instance database, which you can make into RAC in the
next step, using srvctl. When you use "restore database", RMAN command,
the target database to which you are connected must not have
cluster_database parameter set to TRUE. You can get parallelism by
allocating multiple channels, unless your database is Oracle SE. Oracle SE
doesn't allow multiple channels, but it does support RAC.
