  2. 1.丢失数据文件(ORA-01157)
    SQL> startup
    ORACLE instance started.

    Total System Global Area 260046848 bytes
    Fixed Size 1266896 bytes
    Variable Size 83888944 bytes
    Database Buffers 167772160 bytes
    Redo Buffers 7118848 bytes
    Database mounted.
    ORA-01157: cannot identify/lock data file 4 – see DBWR trace file
    ORA-01110: data file 4: ‘/u01/oracle/oradata/XFF/users01.dbf’
    数据文件丢失,处理方法:
    1).使用备份还原丢失数据然后
    2).非undo,system可以offline 掉该文件继续打开数据库
    3).如果是undo需要谨慎,可能导致ORA-00376错误
    4).如果是system offline可能导致ORA-01147

    2. 丢失redo(ORA-00313)
    SQL> startup
    ORACLE instance started.

    Total System Global Area 260046848 bytes
    Fixed Size 1266896 bytes
    Variable Size 83888944 bytes
    Database Buffers 167772160 bytes
    Redo Buffers 7118848 bytes
    Database mounted.
    ORA-00313: open failed for members of log group 1 of thread 1
    ORA-00312: online log 1 thread 1: ‘/u01/oracle/oradata/XFF/redo01.log’
    ORA-27037: unable to obtain file status
    Linux Error: 2: No such file or directory
    Additional information: 3
    redo文件丢失,处理步骤:
    1).查询v$log确认该redo是否是current或者active
    2).确定该redo是否被归档
    3).如果是inactive使用clear 或者 clear unarchived
    4).如果是active或者current,需要通过不完全恢复,甚至隐含参数等方法解决

    3. 丢失undo(ORA-01092 ORA-00376)
    SQL> startup
    ORACLE instance started.

    Total System Global Area 260046848 bytes
    Fixed Size 1266896 bytes
    Variable Size 83888944 bytes
    Database Buffers 167772160 bytes
    Redo Buffers 7118848 bytes
    Database mounted.
    ORA-01157: cannot identify/lock data file 2 – see DBWR trace file
    ORA-01110: data file 2: ‘/u01/oracle/oradata/XFF/undotbs01.dbf’

    SQL> alter database datafile 2 offline drop;

    Database altered.

    SQL> alter database open;
    alter database open
    *
    ERROR at line 1:
    ORA-01092: ORACLE instance terminated. Disconnection forced

    ORA-01092是前台错误,通过查询alert日志发现后台错误主要是:
    Fri Oct 25 08:16:36 2013
    Errors in file /u01/oracle/admin/XFF/bdump/xff_smon_7437.trc:
    ORA-00604: error occurred at recursive SQL level 1
    ORA-00376: file 2 cannot be read at this time
    ORA-01110: data file 2: ‘/u01/oracle/oradata/XFF/undotbs01.dbf’
    因为undo文件丢失,有事务无法正常回滚,从而出现该错误,需要通过使用隐含参数屏蔽事务来解决

    4. 丢失system(ORA-01147)
    SQL> startup
    ORACLE instance started.

    Total System Global Area 260046848 bytes
    Fixed Size 1266896 bytes
    Variable Size 83888944 bytes
    Database Buffers 167772160 bytes
    Redo Buffers 7118848 bytes
    Database mounted.
    ORA-01157: cannot identify/lock data file 1 – see DBWR trace file
    ORA-01110: data file 1: ‘/u01/oracle/oradata/XFF/system01.dbf’

    SQL> alter database datafile 1 offline drop;

    Database altered.

    SQL> alter database open;
    alter database open
    *
    ERROR at line 1:
    ORA-01147: SYSTEM tablespace file 1 is offline
    ORA-01110: data file 1: ‘/u01/oracle/oradata/XFF/system01.dbf’
    system表空间是系统表空间,该表空间中的数据文件不能被offline,如果该表空间数据文件丢失,数据库无法正常方法,可以考虑使用bbed模拟system文件欺骗数据库(非file# 1)或者使用dul抽取数据

    5. 丢失控制文件(ORA-00205 ORA-00202)
    SQL> startup
    ORACLE instance started.

    Total System Global Area 260046848 bytes
    Fixed Size 1266896 bytes
    Variable Size 83888944 bytes
    Database Buffers 167772160 bytes
    Redo Buffers 7118848 bytes
    ORA-00205: error in identifying control file, check alert log for more info

    ORA-00205是前台错误,具体需要结合日志分析:
    Fri Oct 25 08:35:40 2013
    ALTER DATABASE MOUNT
    Fri Oct 25 08:35:40 2013
    ORA-00202: control file: ‘/u01/oracle/oradata/XFF/control01.ctl’
    ORA-27037: unable to obtain file status
    Linux Error: 2: No such file or directory
    Additional information: 3
    这里可以看出来,是因为控制问文件丢失该值该错误,处理办法:
    1).使用备份控制文件还原
    2).查找是否还有其他控制文件,拷贝一份
    3).列举数据文件重建控制文件
