title: Can I use Oracle JDBC 12.1.0.1 (for 12c database) on a Oracle 10g database?
body: <p>Just a simple question (I guess). Oracle released a new <a href="http://www.oracle.com/technetwork/database/features/jdbc/jdbc-drivers-12c-download-1958347.html">JDBC driver for Oracle Database 12c</a> including a Java 7 JDBC driver (ojdbc7 - 12.1.0.1). Here, we've been using <strong>Oracle 10g database</strong> with ojdbc6 for Oracle 11g (11.2.0.4) without any problem. Now, my questions.</p>
  
  <p>If I upgrade my application server to use ojdbc7 for Oracle 12c, is it too risk? Does the Oracle maintains compatibility of their drivers with previous versions?</p>
