shutdown abort模式
丢失redo log
无法open数据库
通过告警报错ORA-00354: corrupt redo log block header 从该错误可以看出当前日志的redo block的header出现问题，导致oracle无法读取redo进行恢复。通过以下检查发现数据库文件头都一致，没有需要恢复的文件，但是由于数据库是非正常关闭，last_change scn没有被写入，数据库判断需要恢复，则读取相应的redo log group 3，但是此时该文件已经损坏。

SYS@orcl11g>alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery

SYS@orcl11g>recover database;

ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: '/opt/oracle/oradata/orcl11g/system01.dbf'

加入以下隐含参数：
SYS@orcl11g>show parameter _allow
NAME     TYPE   VALUE
------------------------------------ ---------------------- ------------------------------
_allow_error_simulation  boolean  TRUE
_allow_resetlogs_corruption  boolean  TRUE

这时候发现数据库时可以打开的

SYS@orcl11g>
SYS@orcl11g>
SYS@orcl11g>alter database open resetlogs;

Database altered.

SYS@orcl11g>

发现日志文件已经被重建：
SYS@orcl11g>select group#,status from v$log;
 GROUP# STATUS
---------- ------------------------------------------------------------
  1 CURRENT
  2 UNUSED
  3 UNUSED

SYS@orcl11g>alter system switch logfile;

System altered.

SYS@orcl11g>/

System altered.

SYS@orcl11g>/

System altered.

SYS@orcl11g>select group#,status from v$log;
 GROUP# STATUS
---------- ------------------------------------------------------------
  1 CURRENT
  2 INACTIVE
  3 ACTIVE
