ORA-00257: archiver error. Connect internal only, until freed 錯誤的處理方法

archive log 日誌已滿
ORA-00257: archiver error. Connect internal only, until freed 錯誤的處理方法

1. 用sys用戶登陸
   sqlplus sys/pass@tt as sysdba

2. 看看archiv log所在位置
SQL> show parameter log_archive_dest;
NAME                                     TYPE        VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest                   string
log_archive_dest_1               string
log_archive_dest_10             string

3. 通常VALUE爲空時，能夠用archive log list;檢查一下歸檔目錄和log sequence
SQL> archive log list;
Database log mode                 Archive Mode
Automatic archival                   Enabled
Archive destination                  USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     360
Next log sequence to archive  360
Current log sequence              362

4. 檢查flash recovery area的使用狀況,能夠看見archivelog已經很大了，達到96.62
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;

FILE_TYPE    PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
------------ ------------------ ------------------------- ---------------
CONTROLFILE                 .13                        0               1
ONLINELOG                  2.93                        0               3
ARCHIVELOG                96.62                       0              141
BACKUPPIECE                   0                         0               0
IMAGECOPY                      0                         0               0
FLASHBACKLOG                0                         0               0

5. 計算flash recovery area已經佔用的空間
SQL> select sum(percent_space_used)*3/100 from v$flash_recovery_area_usage;

SUM(PERCENT_SPACE_USED)*3/100
-----------------------------
                        2.9904
                       
6. 找到recovery目錄, show parameter recover
SQL> show parameter recover;
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string           /u01/app/oracle/flash_recovery_area
db_recovery_file_dest_size        big integer   5G
recovery_parallelism                   integer         0

                      
7 上述結果告訴咱們，歸檔位置用的是默認值，放在flash_recovery_area下(db_recovery_file_dest目錄=/u01/app/oracle/flash_recovery_area)
[root@sha3 10.2.0]# echo $ORACLE_BASE
/u01/app/oracle

[root@sha3 10.2.0]# cd $ORACLE_BASE/flash_recovery_area/tt/archivelog
轉移或清除對應的歸檔日誌, 刪除一些不用的日期目錄的文件，注意保留最後幾個文件（好比360之後的）

---------------------------------------------------------------------------------------
注意:
在刪除歸檔日誌後，必須用RMAN維護控制文件，不然空間顯示仍然不釋放。
---------------------------------------------------------------------------------------

8. rman target sys/pass
[root@sha3 oracle]# rman target sys/pass

Recovery Manager: Release 10.2.0.4.0 - Production on Tue Jan 20 01:41:26 2009

Copyright (c) 1982, 2007, Oracle.  All rights reserved.

connected to target database: tt (DBID=4147983671)

9. 檢查一些無用的archivelog
RMAN> crosscheck archivelog all;

10. 刪除過時的歸檔
RMAN> delete expired archivelog all;

delete archivelog until time 'sysdate-1' ; 刪除截止到前一天的全部archivelog

11. 再次查詢，發現使用率正常，已經降到23.03
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;

FILE_TYPE    PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
------------ ------------------ ------------------------- ---------------
CONTROLFILE                 .13                         0               1
ONLINELOG                  2.93                         0               3
ARCHIVELOG                23.03                         0              36
BACKUPPIECE                   0                         0               0
IMAGECOPY                     0                         0               0
FLASHBACKLOG                  0                         0               0

其它有用的Command:
----------------------------------
若是archive log模式下不能正常startup,則先恢復成noarchive log,startup成功後，再shutdown;
shutdown immediate;
startup mount;
alter database noarchivelog;
alter database open;
shutdown immediate;

再次startup以archive log模式
shutdown immediate;
startup mount;
show parameter log_archive_dest; 
alter database archivelog;
archive log list;                
alter database open;

若是還不行，則刪除一些archlog log
SQL> select group#,sequence# from v$log;

    GROUP# SEQUENCE#
---------- ----------
          1         62
          3         64
          2         63

原來是日誌組一的一個日誌不能歸檔
SQL> alter database clear unarchived logfile group 1;
alter database open;

最後，也能夠指定位置Arch Log, 請按照以下配置
select name from v$datafile;
alter system set log_archive_dest='/opt/app/oracle/oradata/usagedb/arch' scope=spfile

或者修改大小
SQL> alter system set db_recovery_file_dest_size=3G scope=both;
