I am using Oracle Enterprise Manager 13c. I have created an incident rule to get email if database goes down.
But, it send me frequently database down alert and immediately alert clear email, where
Root Cause Analysis Status=Neither Cause Nor Symptom
Causal analysis result=Neither a cause nor a symptom
This is happening for OMS database and another database I have registered to monitor. Both OMS and other database is Multi-tenant database.
OMS Database Version: 188.8.131.52.0
Other Database Version: 184.108.40.206.0
Oracle Enterprise Manager Cloud Control OMS 13c Release 3
Though there is a option to skip Fatal Severity in the incident rule, But I was trying to find the root cause.
