The Master SNMP Agent is running on the system but has not been configured to communicate with the Intelligent Agent.
An NMS-00004 error is caused by the Oracle Intelligent Agent process not being able to communicate with the Master SNMP Agent process during startup.
Following these steps will allow this communication to be successful.
Solution Description: If you do not need the Master SNMP Agent (snmpd) on process running on the server, you can stop the process and then restart the Intelligent Agent.
1. Get the process id of snmpd:
# ps -ef |grep snmpd
Stop the processs:
# kill -9 (enter the process number obtained in step 1)
2. On AIX however, the 'stopsrc' and 'startsrc' command can be used
to stop and start system deamons.
To stop the SNMP daemon on AIX, issue the following
# stopsrc -s snmpd
3. Restart the Intelligent Agent
$ lsnrctl dbsnmp_start
