Solution

I think your WebLogic AdminServer is locked when you try shutdown. Can you delete .lok files in your AdminServer directory or check Lock & Edit function in WebLogic console?

EDIT: If not able to delete .lok files and you want to stop WebLogic you can use the nmkill command. I don't know what type of OS you use. I always use kill -9command in Unix to stop WebLogic. To start WebLogic server you first need to start NodeManager and after the AdminServer. Here is nmStart command.
