在解決由於一次誤操作而引起的Oracle數據庫大恢復的過程中， 由於shutdown abort實例有時起不到解決的作用，於是我們就采用殺Oracle進程，來刪除其共享內存段的做法，將掛起Oracle數據庫實力強制abort。
1、殺Oracle核心進程

2、刪除Oracle 共享內存段

在一次誤操作引起的Oracle數據庫大恢復的解決辦法中再次嘗試將實例打開，這裡用到了10015事件。
引用
- SQL> alter session set events '
10015 trace name adjust_scn level 1';- Session altered.
- SQL> alter database open;
- alter database open
- *
- ERROR at line 1:
- ORA-01113: file 1 needs media recovery
- ORA-01110: data file 1:
'/ora10g/app/oradata/ldbra/system01.dbf'- SQL> recover database;
- Media recovery complete.
- SQL> alter database open;
- Database altered.
後續工作就是將tempfile添加到temp表空間中，終於恢復成功。
引用
- SQL> alter tablespace temp add tempfile
'/ora10g/app/oradata/ldbra/temp01.dbf' size 50m reuse;- Tablespace altered.
