We have changed sys and system password for a database, and updated monitoring credentials in OEM for the database and its data guard copy database.Still we are receiving this alert continuously after that.
"Number of failed Login attempts exceeds the thereshold value."
Please suggest what can be the reason.
Which credentials do you use for OEM monitoring? From which target does the error emanate from, primary or standby?
Hopefully your audit trail is set to DB, if so, have you checked the source of the failed login attempts?
