昨晚下班的時候，我准備關閉本機的虛擬機上的ORACLE數據庫後准備下班，但是由於我SecureCRT開了多個窗口，結果一不小心，疏忽之下在一個生產服務器上執行了shutdown immediate命令，大概過了6到7秒，發現該命令還沒有響應，我才發現我這個命令執行錯了服務器。一驚之下，想都沒有想直接CTRL+C想中斷這個操作。 如下所示：
SQL> shutdown immeidate;
SP2-0717: illegal SHUTDOWN option
SQL> shutdown immediate;
^C^C^C^C^C
ORA-01013: user requested cancel of current operation
於是我在另外一個窗口裡面查看了一下告警日志文件，發現數據庫已經關閉了一些進程。大體情況如下所示

於是立馬查看數據庫的狀態，看看是否正常，結果如下所示，出現了ORA-00604、ORA-00376、ORA-01110等錯誤。
SQL> SQL> SQL> select status from v$instance;
select status from v$instance

ERROR at line 1:

ORA-00376: file 1 cannot be read at this time
ORA-01110: data file 1: '/u01/oradata/SCM2/system01.dbf'
一驚之下，立馬退出了會話，重新登錄後（當時不怎麼冷靜，慌忙之下已經不談定了）

此時告警日志裡面有大量的這類錯誤。
無奈之下，我只能使用shutdown abort命令了，這時候我反而冷靜下來。但是居然報ORA-01031: insufficient privileges 錯誤，立馬退出然後重新登錄後，將數據庫關閉然後重新啟動。
SQL> shutdown abort

重新啟動後，監控告警日志，發現沒有異常出現，逐個檢查後發現沒有什麼問題，一顆懸著的心才淡定下來。不過還是要總結一下：這是一次低級失誤，也是印象比較深的一次失誤，我之所以要記錄下來，一來這也是一個案例，二來要自己謹記於心。整個過程中，發現自己一直不冷靜、不談定。其實本來已經shutdown了數據庫，那應該先冷靜分析一下，到底是等數據庫關閉後重新啟動，還是中斷這個進程。 本身ORACLE數據庫已經關閉了一些進程，如果此時中斷shutdown 進程，明顯是個不明智的決定。錯誤的決策導致後面一系列問題的出現，典型的修為不夠！ 老大給我的郵件叫我下次應該 relax, calm down and be careful 。 謹記於心。
你這些顯示的文件夾路徑有沒有在物理磁盤上創建呢？還有就是你用init.ora文件創建的pfile裡需要修改幾個地方，例如數據庫名，添加控制文件等。
另外建議你改變一下語言，這樣錯誤容易看懂。
alter session set nls_language=american;
shutdown abort 強制關閉
再 startup # 自動進行實例恢復
正常登陸
