Sorry... I hit the wrong button on my keyboard!

As I was saying. This would be perfectly acceptable:

INST1.log_archive_dest_1=/ocfs/partition1/archives INST2.log_archive_dest_2=/ocfs/partition1/archives *.log_archive_format=arch%s_%t.rdo

When you see a "*" in front of a parameter it means "this applies to all instances". If you see a specific instance name, then the value only applies to the specifically-named instance.

I think you've a bit of reading to do before plunging much further into RAC.
