Hi everyone
Now we controlling this oem alert message and solution this message. First of all search alert source in oem.
Our target hosts send mail alert from grid listener. Check oracle support this state and apply this document step (Doc ID 2009044.1)
Look listener.ora home location. For example grid_1/network/admin/listener.ora
Add this parameter to listener.ora
LOCAL_OS_AUTHENTICATION_LISTENER=OFF
Afterly restart grid listener. For example lsnrctl stop & lsnrctl start.
Now resolved this problem.
