Please guide me and how to solve the error and i want to change my database protection_mode to MAXIMUM AVAILABILITY.
ORA-3113 is a generic error. What is the alert log file telling you?
You have to check if there are any trace files generated, or any core dumps.
If there is only a core dump, then you might want to check the call stack and see if the functions are pointing to any known issue in metalink.
