title: ORA-12154: TNS:could not resolve the connect identifier specified (PLSQL Developer)
body: <p>I need to use PLSQL Developer to access oracle databases. I get the following error when I try to connect to my database. <code>ORA-12154: TNS:could not resolve the connect identifier specified.</code> I am able to use SQLPLUS from the command line to connect to the database, and <b>tnsping</b> returns successfully, but I can't figure out why PLSQL Developer will not work - it's using the right <i>tnsnames.ora</i> file, and the connection string in there is correct because it's the same one that <b>tnsping</b> uses.</p>
  
  <p>Anyone have an idea what I can do to fix this? I've looked at other threads about this specific error with no luck.</p>
