ORA-03113: end-of-file on communication channel

Hello,
While trying to open database encounter that error : ORA-03113: end-of-file on communication channel

[oracle@oel6 admin]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Productionon Tue Sep 3 14:31:43 2013

Now see alert.log file

[oracle@oel6 admin]$ cd /u0/app/oracle/diag/rdbms/orcl/orcl/trace/
tail -100 alert_orcl.log

shows last 100 row in alert log file, which tells that
ORA-19815: WARNING: db_recovery_file_dest_size of 5368709120 bytes is 100.00% used, and has 0 remaining bytes available.
We have following choices
1) Add disk space and increase db_recovery_file_dest_size parameter
2) 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.
now we show second method, delete archivelogs with operating system command.

[oracle@oel6 trace]$ . oraenv
ORACLE_SID = [+ASM] ? 
The Oracle base remains unchanged with value /u0/app/oracle
[oracle@oel6 trace]$ asmcmd

after that we can startup database

[oracle@oel6 trace]$ . oraenv
ORACLE_SID = [+ASM] ? orcl
The Oracle base remains unchanged with value /u0/app/oracle
[oracle@oel6 trace]$ sqlplus / as sysdba
