I have configured single instance logical standby from two node RAC. It was working fine, but in between it started giving this message: "Archive log rejected (thread 2 sequence 2816) by RFS clients" also similar message for two other log sequences.
These archives are present in standby_archive_dest area. However many more files are archived to this location after these and standby is working fine, but i am continuously getting this message for 3 archives every 45 mins in alert log on standby.
I tried to register these files as: alter database register logical logfile..." but this throws error saying file already registered.
Anybody faced this issue or have any idea how to resolve this, please help at earliest.... Thank you very much in advance
