Re: adding Instances to a 2-Node OPS

Yes, it is possible to add a node.

I can't give you the specifics, because I'm more familiar with RAC, but the general principle is that you'll need to create a new init.ora, specifying the new instance_name and instance_number. You'll need to alter the existing init.oras to set active_instance_count (something like that, anyway) to allow three instances. You'll need to use one of the existing instances to add a new thread of at least two redo logs to the database (alter database add log group X 'path/filename' thread 3;). And the new instance either needs to have its own set of private rollback segments created (by one of the existing instances) or there needs to be sufficient public rollback segments that it can acquire some of them for its own use.

More specific than that, I'm afraid I can't get, without diving into the doco. (which you can do too, of course)
