Ok, Looking over all of the messages I'd say there are potentially two problems: 1) is sqlnet connectivity between the two databases possible and yes I mean between both in both directions. MRP0 will always start and is waiting for the next redo log needed. Not having RFS up means to me that there is a problem with the sqlnet connectivity. Either the standby cannot connect to the primary thereby stating the transfer of the current log file or your standby destination is disabled. Take a look at the primary site's alert log. 2) Your fal server/fal client setup is fouled up. Yes the server is the primary db sqlnet alias on the standby side and the fal_cleint needs to be the service specified in the archive_log_dest_x parameter on the primary and that destination HAS to be enabled.
