I have one query regarding Gap detection & resolution.
1) On a 10.2.0.4 DB with physical standby, gap detection and resolution happened using automatic gap resolution without setting FAL_server and FAL_Client on the standby. So I would like to know why should one set the said parameters?
it's says that automatic gap resolution doesn't require any setting but primary should be available. For FAL_SERVER, you can specify name for other standby by , oracle stream also from where you can get the archive log too, in case primary not available for some reason.
