Oracle 10g默認的歸檔日志存放在flash_recovery_area，如果歸檔日志超過了默認值的大小,則會報ORA-16014的錯誤.
1.出錯
SQL*Plus: Release 10.2.0.2.0 - Production on Sun May 30 10:32:43 2010

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - Production
With the Partitioning, Oracle Label Security, OLAP and Data Mining options
SQL> startup mount

ERROR at line 1:
ORA-16014: log 1 sequence# 86 not archived, no available destinations
ORA-00312: online log 1 thread 1: '/u01/app/oracle/oradata/orcl/redo01.log'
2.查看歸檔日志區的大小
SQL> show parameter db_rec
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /u01/app/oracle/flash_recovery
_area
db_recovery_file_dest_size big integer 2G
db_recycle_cache_size big integer 0
3.檢查flash recovery area的使用情況
SQL> select * from v$flash_recovery_area_usage;
FILE_TYPE PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
------------ ------------------ ------------------------- ---------------
CONTROLFILE 0 0 0
ONLINELOG 0 0 0
ARCHIVELOG 98.77 0 52
BACKUPPIECE 0 0 0
IMAGECOPY 0 0 0
FLASHBACKLOG 0 0 0
6 rows selected.
SQL> select sum( PERCENT_SPACE_USED )*3/100 from v$flash_recovery_area_usage;
SUM(PERCENT_SPACE_USED)*3/100
-----------------------------
2.9631
4.計算后,發現使用了2.96G>2G,將值設為4G,重新啟動,成功
SQL> alter system set db_recovery_file_dest_size =4G;
System altered.
SQL> alter database open;
Database altered.
