Flash Recovery Area is Full

Below I have mentioned tow step by step recovery solutions. Based on your environment you can choose the option.

Solution 1

If you have enough disk space available, you can increase the db_recovery_file_dest_size larger.
1. Log into the database as sysdba and find out the present db recovery file size.
Open Command Prompt
c:> sqlplus /nolog
SQL> connect sys/manager as sysdba
SQL>show parameter db_recovery_file_dest
2. Increase the size to higher .
SQL> alter system set db_recovery_file_dest_size = 10g;
System altered.
SQL> shutdown abort
ORACLE instance shut down.
SQL> startup

Solution 2

Free up the space from flash recovery area.
1. Log into the database as sysdba and find out the location log.
Open Dos Command Prompt
c:> sqlplus /nolog
SQL> connect sys/manager as sysdba
SQL>show parameter db_recovery_file_dest

2.  Delete unwanted old archive log files manually (rm/del).
go to C:oracleproduct10.2.0flash_recovery_areaORCLARCHIVELOG
Manual deleting will not clear the entries in rman
3.  Log in to rman and delete the expired the archive log entries.
Go to Command Prompt
>rman target /
connected to target database: ORCL (DBID=1202273786)

RMAN > show all;
RMAM > crosscheck archivelog all;
This will updates the manually deleted log files as expired.
RMAN > delete expired archivelog all;
4. Login to sql and Restart the service.
SQL> shutdown abort
ORACLE instance shut down
SQL> startup
