I'm new to the OEM, I'll be very appreciated if I can get some help from you.
I'm trying to use the OEM dbsnmp to send the trap out when the oracle db is going down. I'm writing a SNMP Manager running on different node to receive the trap from OEM. My questions are:
1. Which port (162 ?) this Manager should listen to in order to receive the traps? Are the traps generated automatically by the dbsnmp or it requires some kind of configuration from the OEM console in order for this trap to be generated ?
2. Since my SNMP Manager receives the traps from dbsnmp directly, do I need to run the Oracle Manager Server?
3. Where I can find the Enterprise Manager MIB file that contains the oraAgentTraps variables ?
