oracle 频繁宕机 ORA-00600: internal error code, arguments: [krccacp_badfile]

oracle出现频繁宕机,日志报如下错误:

CTWR: terminating instance due to error 487
Instance terminated by CTWR, pid = 12511

 

CTWR,其全称为Change Tracking Writer,用于记录变化的块并将变化写入相应的日志文件中。

 Block chage tracking是Oracle10g的一个新特性,Block change tracking进程记录自从上一次备份以来数据块的变化,并把这些信息记录在跟踪文件中。RMAN使用这个文件判断增量备份中需要备份的变更数据。这极大的促进了备份性能,RMAN可以不再扫描整个文件以查找变更数据

 

Block chage tracking是Oracle10g的一个新特性,Block change tracking进程记录自从上一次备份以来数据块的变化,并把这些信息记录在跟踪文件中。RMAN使用这个文件判断增量备份中需要备份的变更数据。这极大的促进了备份性能,RMAN可以不再扫描整个文件以查找变更数据。

为此Oracle引入了一个新的后台进程,CTWR,其全称为Change Tracking Writer,用于记录变化的块并将变化写入相应的日志文件中。
启用跟踪可以使用如下命令取消掉CTWR检查设置:

alter database enable block change tracking using
file '/data5/flash_recovery_area/EYGLE/eygle_block_track.log';

判断当前设置可以查询:
select filename,status,bytes from v$block_change_tracking;

关闭跟踪:
alter database disable block change tracking;

以下步骤供参考:

SYS AS SYSDBA on 29-MAR-05 >alter database enable block change tracking using
  2  file '/data5/flash_recovery_area/EYGLE/eygle_block_track.log';

Database altered.

SYS AS SYSDBA on 29-MAR-05 >select filename,status,bytes from v$block_change_tracking;
