I have followed the below steps Navigate to tmp folder in your $DOMAIN_HOME directory. (for example: C:\Oracle\Middleware\Oracle_Home\user_projects\domains\mydomain\servers\AdminServer\tmp) Delete the lock file for the server instance, AdminServer.lok Check if there are any java.exe processes are running, which should not be there. If there are any, they would have to be killed. Restart your server
But still getting the same error
