Gap Detection & Resolution

Hello all,

I have one query regarding Gap detection & resolution.

1) On a 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?

Thanks and regards

    Well, please refer to below link

    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.

    On Oracle 10 FAL_SERVER and FAL_CLIENT are only required if the other parameter is specified.

    When a database is running in the standby role, it uses FAL_SERVER from which to fetch (request) missing archived redo log files if Primary is unable to automatically send the missing log files.

    Best Regards
