libclntsh.so.11.1: cannot open shared object file

  程式執行時會提示以下錯誤：

 libclntsh.so.11.1: cannot open shared object file: No such file or directory

   解決方案為：

The libs are located in /u01/app/oracle/product/11.2.0/xe/lib (For
Oracle XE) or similar.

You should add this path to /etc/ld.so.conf or
if this file shows only an include location, as in a separate file in the /etc/ld.so.conf.d directory

I have oracle.conf in /etc/ld.so.conf.d,
just one file with the path. Nothing else.

Of course don't forget to run ldconfig as a last step.
