title: Cannot connect to Oracle database via TCPS
body: <p>We have an Oracle server set up and are using TCP with SSL as connection. This setup was made with the assistant wizard and we used the default settings pretty much everywhere (which also means that no tnsnames.ora or listener.ora exist). <code>lsnrctl status</code> shows that the correct ports are listening.</p>
  
  <p>We are trying to connect to this database via DBeaver and SQuirrel SQL but cannot get it to work. We have set the vmargs for the programs to contain the certificate of the server (e.g. <code>dbeaver.exe -vmargs -Djavax.net.ssl.trustStore=C:/...keystore.jks -Djavax.net.ssl.trustStorePassword=password -Djavax.net.ssl.trustStoreType=JKS</code>), which works fine.</p>
  
  <p>Connecting to the database with a concrete JDBC URL string (<code>jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCPS)(HOST=IP)(PORT=5500))(CONNECT_DATA=(SERVICE_NAME=testdb)))</code>) does not work and times out after 60 seconds without a proper error (IO Error: Got minus one from a read call). We have tried pretty much everything and cannot get it to work.</p>
  
  <p>The ports are correctly assigned, the database can successfully get accessed with the normal TCP protocol and port 1521.<code>jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=IP)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=testdb)))</code></p>
  
  <p>Are we missing steps? There don't seem to be any firewall issues. The certificates seem to be working fine as well, but we cannot connect with any of the programs (or sqlplus via command line).</p>
  
  <p>Anyone know what could be the problem? Thanks!</p>
