消灭ORA-16014

消灭ORA-16014

Oracle 10g默认的归档日志存放在flash_recovery_area，如果归档日志超过了默认值的大小,则会报ORA-16014的错误.

1.出错

2.查看归档日志区的大小

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.检查flash recovery area的使用情况

SQL >   select   *   from  v$flash_recovery_area_usage;

FILE_TYPE    PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
-- ---------- ------------------ ------------------------- ---------------
CONTROLFILE                    0                           0                 0

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.计算后,发现使用了2.96G>2G,将值设为4G,重新启动,成功

SQL >   alter  system  set  db_recovery_file_dest_size  = 4G;

System altered.

SQL >   alter   database   open ;

Database  altered.
