sysaux在沒有備份的情況下，資料塊損壞，資料庫啟動不了處理
具體的思路：
(一) 考慮在控制檔案中把sysaux表空間給剔除掉，啟動資料庫
1 建立控制檔案
alter database backup controlfile to trace as '/oracle/DEV/control01.bak';
2 檢視/oracle/DEV/control01.bak內容
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "DEV" NORESETLOGS ARCHIVELOG
MAXLOGFILES 255
MAXLOGMEMBERS 3
MAXDATAFILES 254
MAXINSTANCES 50
MAXLOGHISTORY 4041
LOGFILE

GROUP 3 (

) SIZE 50M BLOCKSIZE 512,
GROUP 4 (

) SIZE 50M BLOCKSIZE 512

3 啟動資料庫nomount狀態下，排除資料檔案'/oracle/DEV/sapdata1/sysaux_1/sysaux.data1',
建立控制檔案

Control file created.
4 開啟資料庫
Control file created.
SQL> SQL> SQL> SQL> SQL> SQL> alter database mount;
alter database mount
*
ERROR at line 1:
ORA-01100: database already mounted
SQL> alter database open;
Database altered.
5 檢測資料的完整性
SQL> select name from v$tablespace;
NAME
------------------------------
SYSTEM
PSAPUNDO
PSAPSR3
PSAPSR3702
PSAPSR3USR
SYSAUX
PSAPTEMP
7 rows selected
注：SYSAUX表空間是存在的，使用select訪問各表，均可以訪問，故資料是完成的
7 設定sysaux表空間為offline
SQL> alter tablespace sysaux offline;
alter tablespace sysaux offline
*
ERROR at line 1:
ORA-01191: file 2 is already offline - cannot do a normal offline
ORA-01111: name for data file 2 is unknown - rename to correct file
ORA-01110: data file 2: '/oracle/DEV/112_64/dbs/MISSING00002'
注：這樣設定後，其實資料檔案已經offline
(二) 在其他伺服器上建立資料庫
略
(三) 把資料匯入新建資料庫中
sapdb:oradev 80> exp sapsr3/Geely123 file=sap.dmp owner=sapsr3 rows=n buffer=6500000
