title: libsqlplus.so: connot open shared object file : No such file or directory even though PATH contain the path
body: <p>I downloaded Instant Oracle Client Version 11.2.0.4.0(<code>basic</code>, <code>sqlplus</code>, <code>devel</code> .rpm file) by <a href="http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html" rel="noreferrer">Oracle website</a> in Ubuntu.
  After converting <code>.rpm</code> into <code>.deb</code> using <code>alien</code>, I installed it, <code>basic</code> first and <code>sqlplus</code> and last <code>devel</code>.</p>
  
  <p>And then I tried to run sqlplus.</p>
  
  <p>But It is saying <code>sqlplus64: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory</code></p>
  
  <p>Even though my <code>PATH</code> contains the <code>PATH</code>.</p>
  
  <p>The below shows my <code>PATH</code> and the location of <code>libsqlplus.so</code>.</p>
  
  <pre><code>A@ubuntu:~$ sudo find / -name libsqlplus.so
  /usr/lib/oracle/11.2/client64/lib/libsqlplus.so
  
  A@ubuntu:~$ echo $PATH
  /usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/sangmin/eclipse:/usr/lib/oracle/11.2/client64/lib:/usr/lib/oracle/11.2/client64
