Database Crashing after successful restarts

Question

Hi Guys,
I am sort stuck in a process where my DB is starting but after a few seconds its starts shutting down all the processes.  The system was running perfectly before but after todays restart this is all happening.
the following is the log from the startup to shutdown. Can any one help to figure out what is causing this issue.
This is ORACLE 11G on Enterprise LINUX._

Were these part of a Database Creation using DBCA (The Database Creation Assistant) ?
