If you face the error Unable to reserve the .lok file for Integrated WebLogic Serve then the first is you have to kill the process in Task Manager. Open Task Manager & check for java.exe process for higher memory consumption. End the process.

This error happens due to JDeveloper closes unexpected without shutting down IntegratedWebLogicServer
