Starting and Stopping the Intelligent Agent

Oracle Intelligent Agents are processes running on remote nodes in the network. Oracle Enterprise Manager works with Intelligent Agents across the network, to discover the services running on the nodes where the Intelligent Agent resides, monitor events, run jobs, and collect runtime data for real-time performance monitoring and historical analysis. Any platform running an Intelligent Agent can be incorportated into the Oracle Enterprise Manager framework, as long as TCP/IP communication between the Oracle Enterprise Manager middle tier and the Intelligent Agents is possible.

Refer to the Oracle Intelligent Agent User's Guide for detailed information about troubleshooting any Intelligent Agent problems.

Intelligent Agents local to the Management Server will be discovered automatically when the Management Server is started as long as the Intelligent Agent local to the Management Server has been started. In order to discover distributed services, the Intelligent Agents on the nodes where those services reside must be started.

This chapter discusses the following topics:

Please check the Intelligent Agent compatibility matrix in the Oracle Enterprise Manager Readme before installing or using Enterprise Manager. emreadme.txt or emreadme.html is located in the ORACLE_OEM_HOME\RelNotes\EM directory. For example, C:\Oracle\Ora81\RelNotes\EM.

Start the Intelligent Agent from the prompt	net start Oracle<Oracle_Home_Name>Agent
Stop the Intelligent Agent from the prompt	net stop Oracle<Oracle_Home_Name>Agent
Verify status of the Intelligent Agent from the prompt	net start

Note:
Do not use the lsnrctl command to start the Intelligent Agent for Windows NT or Windows 2000. It is not supported. Use the net command for Windows NT or Windows 2000 instead.

Starting and Stopping the Oracle Intelligent Agent on UNIX

On UNIX, Oracle Enterprise Manager uses the lsnrctl to start and stop the Intelligent Agent. The relevant lsnrctl commands to control the UNIX Intelligent Agent are listed in the table below.

If you want to... Enter the command...

Start the Intelligent Agent on UNIX platforms

lsnrctl dbsnmp_start

Stop the Intelligent Agent on the UNIX platform

lsnrctl dbsnmp_stop

Verify status of the Intelligent Agent

lsnrctl dbsnmp_status

If you want to...	Enter the command...
Start the Intelligent Agent on UNIX platforms	lsnrctl dbsnmp_start
Stop the Intelligent Agent on the UNIX platform	lsnrctl dbsnmp_stop
Verify status of the Intelligent Agent	lsnrctl dbsnmp_status

You can also type ps -ef | grep dbsnmp at the command prompt to verify the status of the Intelligent Agent.
