************************************************************************
You have following choices to free up space from flash 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.

Errors in file g:\oracle\product\10.2.0\db_1\admin\ora10g\bdump\ora10g_arc0_3432.trc:
ORA-16038: log 1 sequence# 116 cannot be archived
ORA-19809: limit exceeded for recovery files
ORA-00312: online log 1 thread 1: 'G:\ORACLE\PRODUCT\10.2.0\ORADATA\ORA10G\REDO01.LOG'然後查看對應的trc文件。
一看就知道是閃回恢復區滿了，告警日誌和trc文件中都給出了對應的解決方法。
採用臨時的方法，增大db_recovery_file_dest_size參數值，就能打開數據庫。
SQL> show parameter db_recovery_file_dest_size
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest_size big integer 2G
SQL> alter system set db_recovery_file_dest_size=3G scope=both;
系統已更改。
SQL> alter database open;
數據庫已更改。20120801 -------------------添加---
如果歸檔日誌默認存儲在閃回恢復區中，可以刪除無用的歸檔日誌解決該問題。
RMAN> delete archivelog until time 'sysdate-7';--刪除7天前的無用的歸檔日誌
這個問題很簡單，僅記錄一下，出現問題了，要記得查看相應的告警日誌文件與trc文件。
