title: Cannot connect to Oracle databse from Toad 9.0
body: <p>I am using Oracle 10g version 10.0.2</p>
  
  <p>Few days ago I was able to connect to my database using SQLPlus and Toad 9.0
  Without changing anything, now Im not able to connect to my database from Toad with the following error msg:
  "You have no Oracle client Installed", but Im still able to connect to the database and to perform queries from SQLPlus</p>
  
  <p>So, please what may cause this problem!?</p>
