損壞的是current 的日誌。

設定兩個隱含引數：_ALLOW_RESETLOGS_CORRUPTION = TRUE 和 _corrupted_rollback_segments ，因為redo損壞的時候，undo資料也大都不一致了。

使用隱含引數啟動資料庫：
SQL> create pfile=''''/home/oracle/pfile.tmp'''' from spfile;

File created.

SQL>
SQL> shutdown immediate;
ORA-01109: database not open


Database dismounted.

*.user_dump_dest=''''/oracle/admin/TSMISC02/udump''''

_ALLOW_RESETLOGS_CORRUPTION = TRUE

這個引數的解釋：

然後設定隱含引數 _ALLOW_RESETLOGS_CORRUPTION = TRUE 和 _corrupted_rollback_segments ,因為redo損壞的時候，undo資料也大都不一致
了。
2，open resetlogs之前，先使用recover database using backup controlfile until cancel;
如果此時又遇到600錯誤，就使用ADJUST_SCN事件來調整當前的SCN，如果SCN相差不多，可以通過多次重起資料庫解決。如果scn相差比較多，

可以使用10015 event：
alter session set events ''''10015 trace name adjust_scn level 1'''';
如果SCN相差比較多，可以設定level 2，。。。level 10等 (level 1是每次開啟時將將scn推進1百萬)
