Solutions :-

You can fix the by simple one step. Just delete the AdminServer.lok file from  your domain.

I have deleted below , check the below commands ..

Go to the /tmp directory inside your weblogic domain.

cd  /usr/java/Oracle/Middleware/user_projects/domains/base_domain/servers/AdminServer/tmp

Checking the existing files inside /tmp directory.

dev@jdg-desktop /usr/java/Oracle/Middleware/user_projects/domains/base_domain/servers/AdminServer/tmp $ ls
AdminServer.lok  WebServiceUtils.ser  _WL_internal  _WL_user

 
Now delete the AdminServer.lok file from this /tmp directory.
 

dev@jdg-desktop /usr/java/Oracle/Middleware/user_projects/domains/base_domain/servers/AdminServer/tmp $ rm -rf AdminServer.lok

Hope it will help you.
