Fix: Unable to start WebLogic Admin Server

Issue : Weblogic doesn't start and you will start getting below error message:

<Jul 3, 2014 10:57:38 PM EDT> <Info> <Management> <BEA-141281> <unable to get file lock, will retry ...>

Resolution: 

When a server is starting, a .lok file is created. This is found under $FMW_HOME/servers/SERVERNAME/tmp/SERVERNAME.lok. If the file exists , then it cannot be created and the server cannot start. To correct this delete the existing file or kill the running process that is holding such file.
