oracle数据库错误ORA-01157: cannot identify/lock data file导致表空间无法online
时间：2022-06-29 09:54:25 编辑：袖梨 来源：一聚教程网
朋友和我聊到一个案例,一个表空间本来有一个数据文件(已经有大量数据进入),然后他加入7个数据文件,这个时候他发现他加多了文件,想删除这些数据文件,可是又不怎么懂数据库,直接offline 表空间,然后rm掉相关数据文件,最后表空间无法online.我对其场景进行了模拟恢复测试,使用bbed和dul对其进行恢复
模拟场景
表空间有一个数据文件,里面有数据,然后加入一个新数据文件,进入offline tbs,然后rm数据文件
offline表空间后,该表空间存在的数据文件也会offline
| 代码如下 | 复制代码 |

这里已经构造出来,由于由于数据文件丢失导致表空间online报ORA-01157: cannot identify/lock data file的错误
online存在数据文件
存在的数据文件online之后，表空间依然offline

由于表空间无法online,因此对该表空间分配报ORA-01542错误
使用bbed构造数据文件欺骗数据库

在bbed的恢复过程中出现以下常见错误:
ORA-01122: database file 12 failed verification check
ORA-01110: data file 12: ‘/u01/oracle/ora9i/oradata/xifenfei02.dbf’
ORA-01251: Unknown File Header Version read for file number 12
这个主要是块号和块地址不一匹配,导致数据库无法识别
ORA-01122: database file 12 failed verification check
ORA-01110: data file 12: ‘/u01/oracle/ora9i/oradata/xifenfei02.dbf’
ORA-01203: wrong incarnation of this file – wrong creation SCN
这个由于数据文件头的创建scn和控制文件以及file$中的记录不一致
ORA-01122: database file 12 failed verification check
ORA-01110: data file 12: ‘/u01/oracle/ora9i/oradata/xifenfei02.dbf’
ORA-01207: file is more recent than controlfile – old controlfile
这个由于正常数据文件online过,或者你构造文件头使用的scn大于需要构造文件在控制文件中记录的scn值
后续处理
| 代码如下 | 复制代码 |
| SQL> SELECT COUNT(*) FROM CHF.T_XIFENFEI01; COUNT(*) ---------- 30758 SQL> C/01/02 1* SELECT COUNT(*) FROM CHF.T_XIFENFEI02 SQL> / COUNT(*) ---------- 865 SQL> ALTER DATABASE DATAFILE 12 OFFLINE DROP; Database altered. | |
证明通过bbed,模拟数据文件,使用完美恢复数据内容
dul恢复

这里证明,在表空间不能online的情况下,dul处理类似故障很轻松(但是需要重建表空间,bbed处理的从原理上可以不重建表空间),当然如果涉及的对象很多,而丢失的文件很少,可能bbed也不失为一种很不错的选择.
另外补充:如果表空间丢失的文件包含数据,也可以通过类似bbed和dul方法处理:bbed 让表空间online之后需要考虑跳过丢失文件;dul处理完全相同
总结：
ORA-01157通常由后台进程DBWR锁定而产生。
如果在恢复期间，如数据库已经mount，而一个或多个数据文件不能打开导致数据库不能open时会出现该提示。
数据文件丢失，数据文件的许可问题，如数据文件oracle用户没有写权限等都会产生ORA-01157。
如果open状态的情形下，ORA-01157未列出的数据文件不会受到影响。
补充说明：
细心的朋友应该可能已经发现当时在检查对应的数据文件的时候，只检查了ASM磁盘是否存在对应的数据文件。
由于出错数据库为RAC，因此忽略了检查提示中的文件系统对应的数据文件。说来还是不够仔细，狂汗......
就其原因应该是这样，在使用swingbench时，创建soe表空间时直接一路next，导致将数据文件创建到了文件系统，而文件系统是非共享的。(RAC环境)
