title: Access Oracle 11g database remotely, windows xp server
body: <p>for hours now I am struggling with this. I am complete newbie to Oracle DB 11g and its really to complicated for me :).</p>
  
  <p>I have installed it and it's working properly. With SQL Developer I can connect on localhost, but its not working on other machines.</p>
  
  <p><strong>I HAVE TO USE NORMAL HOST - user/password access.</strong></p>
  
  <p>I am trying <strong>to use EM for editing</strong>, since i don't want to mess up. I have set it up to work remotely. Now... I was trying to configure listener to listen on my (even) internal network IP. But its not working. I have heard about editing TNSNAMES.ORA but I can't find them in EM.</p>
  
  <p>Any help please? What should I do, I am completely confused and all the time I get </p>
