title: oracle instant client and ORACLE_HOME environment variable
body: <p>I have Oracle Server and Oracle Instant Client on the same machine. (Windows 7) </p>
  
  <p>Notes on Instant Client state that get rid of ORACLE_HOME environment variable. </p>
  
  <p>I am using SQL Developer - If I want to install packages, I do not want to hardcode the path, but do something like Oracle_Home/..... (which I don't know the proper syntax of, btw) </p>
  
  <p>How would I achieve this with ORACLE_HOME environment variable gone? </p>
  
  <p>What is the proper syntax? </p>
