Logs files of start and stop operations
are written in 2 files, that use timestamp, see WLS_LOG_START and WLS_LOG_STOP
Create a new file as root in /etc/init.d/weblogic
# vi /etc/init.d/weblogic
and paste inside the following
#!/bin/sh # description: webLogic adminServer and managedServer start script #
