ORA-03113: END-OF-FILE ON COMMUNICATION CHANNEL WHILE STARTUP
My one of the client reported me ORA-03113 oracle error message. He is facing problem while starting up database. Usually this error occurs when connection between Client and Server process was broken OR It can be any big problem.

You have following choices to free up space from recovery area:
1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,
then consider changing RMAN ARCHIVELOG DELETION POLICY.
2. Back up files to tertiary device such as tape using RMAN
BACKUP RECOVERY AREA command.
3. Add disk space and increase db_recovery_file_dest_size parameter to
reflect the new space.
4. Delete unnecessary files using RMAN DELETE command. If an operating
system command was used to delete files, then use RMAN CROSSCHECK and
DELETE EXPIRED commands.

So, I finally assigned more size to Flash recovery area using following command,
and database opened successfully.

I strongly recommend you to monitor your every database move from ADRCI, this will easy for your to understand problem area and act accordingly.
