在Oracle Linux内核上以静默方式安装Oracle 11.2g后,出现以下错误：

[u01/app/oracle/product/11/bin] $sqlplus

sqlplus error while loading shared libraries: libsqlplus.so: cannot open shared  
object file: No such file or directory

但是,共享对象似乎设置正确：

[/u01/app/oracle/product/11/lib] $ls -lrt /u01/app/oracle/product/11/lib | grep sqlplus  
-rw-r--r--. 1 oracle oinstall   1475820 Aug  1  2009 libsqlplus.a  
-rwxr-xr-x. 1 oracle oinstall   1218075 Aug  1  2009 libsqlplus.so

用户是oracle：

[oracle ~]$id oracle  
uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba)

环境变量是：

[oracle ~]$env  
USER=oracle  
LD_LIBRARY_PATH=/u01/app/oracle/product/11/lib  
ORACLE_SID=orcl  
ORACLE_BASE=/u01/app/oracle      
PATH=/usr/lib/qt-3.3/bin:/usr/local/bin
    :/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin: /home/oracle/bin
    :/u01/app/oracle/product/11/bin  
HOME=/home/oracle  
ORACLE_HOME=/u01/app/oracle/product/11  

内核版本：

2.6.32-300.3.1.el6uek.i686

*更新答案*

* chmod / u01 / app / oracle / product / 11 / lib / libclntsh * *之后

$ldd /u01/app/oracle/product/11/bin/sqlplus   
    linux-gate.so.1 =>  (0xb7831000)  
    libsqlplus.so => /u01/app/oracle/product/11/lib/libsqlplus.so (0xb7780000)

    libaio.so.1 => /lib/libaio.so.1 (0x4c446000)  
/lib/ld-linux.so.2 (0x4c424000)  

知道为什么SQLPlus抱怨libsqlplus.so吗？

解决方法:

使libclntsh可执行：

chmod +rx /u01/app/oracle/product/11/lib/libclntsh*

然后再次检查上面注释的ldd命令.
