SNMP subagents that communicate with the master agent. Oracle’s
subagent is a separate executable (dbsnmp
on the
Unix port).
The primary use of Oracle SNMP is that DBAs or data center operators can use a tool such as OpenView to monitor the status of all Oracle databases and listeners on the network. The range of information includes:
Database instance status
Performance problems
Discovery of new databases
Ability to set alerts for various events and configure automatic notification of the appropriate personnel
Ability to store and report on historical data
