    why my database automatically shuts down and restarts


      Hello Experts,


      I'm running my application on Oracle 11.2.0.

      Occasionally, it automatically shuts itself down and restarts for some unknown reasons.

      Extracts from alert log file:


      Shutting down instance (immediate)

      Stopping background process SMCO

      Shutting down instance: further logons disabled


      ....  content deleted.....

      Instance shutdown complete

      Starting ORACLE instance (restrict) / Starting ORACLE instance (normal).


      Anyone has any ideas?


      I appreciate your help.
