title: Oracle PL Sql Developer cannot find my tnsnames.ora file
body: <p>I have an Oracle tnsnames.ora file from my previous workplace. I want to pick it up with my newly installed PL SQL Developer on another computer. I have copied the file into ..ORACLE/product/11.2.0/client_32/NETWORK/ADMIN but PL SQL Developer cannot find it. </p>
  
  <p>When it starts it is not showing me any choice of database.
  In About->i->TNSNames I dont see any lines</p>
  
  <p>I have found a number of advices to look for it in Tools->Preferences->Database->..., but I dont have a Database tab in my preferences.</p>
  
  <p>How can I fix it?</p>
