sqlplus 組件意外被破壞恢複

在執行 sqlplus / as sysdba 命令後沒啥反應,有點奇詭。。。
[oracle@lixora bin]#sqlplus / as sysdba
[oracle@lixora bin]# ls -trl
...
-rwxr-x--x 1 oracle oinstall         0 Dec  9 15:52 sqlplus  -------這個檔案居然被寫空了
...

恢複測試:
從oracle 11201拷貝一個sqlplus 過來,修改完許可權後進行測試:

[oracle@lixora bin]# ls -trl
-rwxr-x--x 1 oracle oinstall      9197 Dec 24 10:26 sqlplus
[oracle@lixora ~]$ sqlplus / as sysdba
SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE may not be functioning properly
[oracle@lixora ~]$ 


關於上述報錯官方解釋:
01503,0, "Unable to initialize Oracle call interface\n"
// *Cause:  Indicates a library used by SQL*Plus to communicate with
//          the database failed to initialize correctly.
// *Action: Check that the Oracle environment or registry entries are
//          consistent and correct.  If using the SQL*Plus Instant Client
//          make sure the SQL*Plus and Oracle libraries are from the
//          same release. Make sure you have read access to the libraries.


00152,0, "ORACLE may not be functioning properly\n"
// *Cause:  Unable to initialize a session to the Oracle instance.
// *Action: Make a note of the message and the number, then contact
//          the Database Administrator.


從報錯的資訊來看主要是sqlplus 無法調用正常的lib 庫檔案,因而無法和/bin/目錄下的oracle(rdbms)進行通訊;
那麼如果是從同平台同版本的oracle 資料庫中拷貝一個sqlplus 組件過來,沒準就能用的?
[oracle@lixora bin]# ls -trl
...
-rwxr-x--x 1 oracle oinstall      7725 Dec 24 10:29 sqlplus


再次測試:
[oracle@lixora bin]$ !sql
sqlplus / as sysdba

來點暴力的,但是感覺和資料庫沒啥關係啊?

一切ok,這裡冒出一個想法,如果 rman or dbca or netca 。。。。意外損壞,是不是也可以按上方法來替換解決呢?找機會測下
