Note: Deleting a startup or shutdown class configuration permanently removes it from the domain's configuration and prevents it from running on all servers to which it has been deployed. If you only want to temporarily stop a startup or shutdown class from running, undeploy it from a server. See Deploy startup and shutdown classes.
Result
WebLogic Server undeploys the class from the targeted servers and removes the class from the domain's configuration file.
After you finish
Note: After you delete a shutdown class, it will run the first time you shut down the server. When you shut down the sever subsequently, it will no longer run.
