Error:  ORA-16401 archivelog rejected by RFS 
---------------------------------------------------------------------------
Cause:  An attempt was made to re-archive an existing archivelog. This usually 
	happens because either a multiple primary database or standby 
	database(s) or both are trying to archive to this standby database. 
Action: See alert log and trace file for more details. No action is necessary; 
	this is an informational statement provided to record the event for 
	diagnostic purposes.

也就是说，啥也不用干，这个信息只是为了说明这个信息而已。
