Undeploy any applications protected by the WebLogic Server/Portal 10 agent.
Restore the deployment descriptors of these applications to their original deployment descriptors. (Backup files are useful here if you have them.)
If you are permanently removing the WebLogic Server/Portal 10 agent, undeploy the agent application.
However, if you plan to re-install this agent , you don't need to undeploy the agent application.
If the WebLogic Server/Portal 10 instance was originally configured using Node Manager, remove the classpath and agent Java options using the WebLogic Server/Portal 10 Administration Console. For more information, see:
Configuring a WebLogic Server 10 Instance With the Agent classpath and Java Options
or
WebLogic Portal 10: Configuring the Agent classpath and Java Options
Ensure that the WebLogic Server/Portal 10 container is stopped.
