今天遇到oracle启动报ORA-01157和ORA-01110的错误sqlgt;startup mount;sqlgt;alter database open;RA-01157: 无法标识/锁定数据
今天遇到Oracle启动报ORA-01157和ORA-01110的错误
sql>startup mount;
sql>alter database open;
RA-01157: 无法标识/锁定数据文件 10 - 请参阅 DBWR 跟踪文件ORA-01110: 数据文件 10: 'D:\ORACLE\ORADATA\ORCL\USERS02.DBF'
解决过程如下：
1. startup mount
2. alter database open
ORA-01157: cannot identify/lock data file 10 - see DBWR trace file
ORA-01110: data file 12: '/oradata/orcldata/sacproduce02.dbf'
3. cd /oradata
4. cd orcldata
报错信息为不能进行读写操作，哈哈。找到原因了，，挂载的硬盘不能进行读写操作了。要打开数据库，只能将该文件进行离线操作了。
5. archive log list
归档模式下
alter database datafile '/oradata/orcldata/sacproduce02.dbf' offline
非归档模式下
alter database datafile '/oradata/orcldata/sacproduce02.dbf'offline drop
6. 到此，数据库就可以open了。但是文件中还有需要的数据，接下来就是挂载硬盘，online数据文件,open数据库。
alter database datafile '/oradata/orcldata/sacproduce02.dbf' online;
ORA-01113: file 12 needs media recovery
ORA-01110: data file 12: '/oradata/orcldata/sacproduce02.dbf'
recover datafile '/oradata/orcldata/sacproduce02.dbf'
alter database datafile '/oradata/orcldata/sacproduce02.dbf' online;
alter database open;
OK,问题解决^_^
