Sun OpenSSO Enterprise Policy Agent 3.0 Guide for Oracle WebLogic Server/Portal 10

Installing the Agent on Multiple WebLogic Server/Portal 10 Instances on the Same Domain

If the agent is installed on a particular domain, you can install the agent on more than one WebLogic Server/Portal 10 instance associated with the same domain by running the agentadmin program again with the -custom-install option. When you are prompted to enter the startup script location and WebLogic Server instance name, enter values for the new instance, so the agent can distinguish between the various instances.
