ORA-00354: 损坏重做日志块标头

ORA-00353: 日志损坏接近块  更改  时间

ORA-00312: 联机日志  线程 : ''

ORA-00354
 oerr ora 354
00354, 00000, "corrupt redo log block header"
// *Cause:  The block header on the redo block indicated by the accompanying
//          error, is not reasonable.
// *Action: Do recovery with a good version of the log or do time based
//          recovery up to the indicated time. If this happens when archiving,
//          archiving of the problem log can be skipped by clearing the log
//          with the UNARCHIVED option. This must be followed by a backup of
//          every datafile to insure recoverability of the database.
ORA-00353
 oerr ora 353
00353, 00000, "log corruption near block %s change %s time %s"
// *Cause:  Some type of redo log corruption has been discovered. This error
//          describes the location of the corruption. Accompanying errors
//          describe the type of corruption.
// *Action: Do recovery with a good version of the log or do incomplete
//          recovery up to the indicated change or time.
ORA-00312
 oerr ora 312
00312, 00000, "online log %s thread %s: '%s'"
// *Cause:  This message reports the filename for details of another message.
// *Action: Other messages will accompany this message. See the
//          associated messages for the appropriate action to take.

症状

在警报日志文件中报告以下错误：

ORA-354: corrupt redo log block header
ORA-353: log corruption near block %s change %s time %s
ORA-312: online log %s thread %s: ‘%s’
ORA-312: online log %s thread %s: ‘%s’

ORA-312 reports all the redo log file names for the same redo log group number.  Example for redo log group number 3 which has two redo log file members:

ORA-00354: corrupt redo log block header
ORA-00353: log corruption near block 1892904 change 878787 time 12/05/2014 13:17:10
ORA-00312: online log 3 thread 1: ‘/oracle/dbs/log3_A.dbf’
ORA-00312: online log 3 thread 1: ‘/oracle/dbs/log3_B.dbf’
两个联机重做日志成员都在错误中被报告。

如果所有重做成员都损坏且数据库在归档日志模式下，警报日志还可能包含下一个信息：

ARCn: All Archive destinations made inactive due to error 354

….

CORRUPTION DETECTED: thread %d sequence %d log %d at block %d. Arch found corrupt blocks

示例：

ARC1: All Archive destinations made inactive due to error 354

….

CORRUPTION DETECTED: thread 1 sequence 28 log 3 at block 1892904. Arch found corrupt blocks

原因

在重做日志组中联机重做日志文件成员中可能的损坏。

如果Oracle在归档一个日志成员时检测到损坏，它会尝试从组中第二个成员读取系统重做块。如果发现重做日志组中所有成员的这个块都是损坏的，归档将无法进行。

原因通常由于错误OS或坏的硬件的overwrite/missed。
解决方案

验证哪些重做日志文件成员损坏

执行下一个语句来确认重做日志成员损坏：

alter system dump logfile ‘&name’ VALIDATE;

这是为了确认重做日志成员已损坏；如果重做日志成员损坏，它应当生成错误。例如：

SQL> alter system dump logfile ‘/oracle/dbs/t_log3.f’ validate;
alter system dump logfile ‘/oracle/dbs/t_log3.f’ validate
*
ERROR at line 1:
ORA-00354: corrupt redo log block header
ORA-00353: log corruption near block 1892904 change 869569 time 12/05/2014 13:17:10
ORA-00334: archived log: ‘/oracle/dbs/log3_A.f’
对同一重做日志组号的所有重做日志文件重复相同步骤。可以执行下一个查询来识别成员：

select member
from v$logfile
where  group# = &group_number;

方案1

如果其中一个重做日志成员未损坏，则多次执行下一个命令直到相应重做日志组号在status=CURRENT视图中处于status=CURRENT。

alter system switch logfile;

select status
from   v$log
where  group#=&log_group_number;

或者等到重做日志被再使用，且块会被修复。

方案2

如果所有重做日志成员都损坏，按照Oracle文档来”clear [unarchived] logfile group”：

Section Clearing a Redo Log File in the Database Administrator’s Guide.

在清理重做日志组后，警告日志可能被更新以下信息：

WARNING! CLEARING REDO LOG WHICH HAS NOT BEEN ARCHIVED. BACKUPS TAKEN
BEFORE [Timestamp] (CHANGE [scn]) CANNOT BE USED FOR RECOVERY.

确保在清理重做日志组创建一个新备份。

同样注意重做日志组号的一个单独成员无法被清理；会生成错误ORA-1514 ：

SQL> alter database clear unarchived logfile ‘/oracle/dbs/log3_A.dbf’;
alter database clear unarchived logfile ‘/oracle/dbs/log3_.dbf’
*
ERROR at line 1:
ORA-01514: error in log specification: no such log
ORA-01517: log member: ‘/oracle/dbs/t_log3_A.dbf’
这是预期的行为。
