Installing the BEA Weblogic SNMP Agent on Windows

, and then configure the SNMP agent.Since the SNMP agent cannot be configured to run as a subagent (only as a master agent), if you are running Oracle on the same host you will have to run the BEA snmp agent on another port (such as 2161). Note that the Oracle agent expects the subagents on port 1161 (and the masquerade agent in Oracle can probably be told to communicate with the BEA snmp agent running on another port).
