Probably you are not closing all the objects. It depends on pool used and app server but is a good idea (and more portable) to close all the objects. Many pools crash if you only close (return) the connections.
after using the rs object (ResultSet) --> rs.close() after using the st object (Statement) --> st.close() after using the pst object (PreparedStatement) --> pst.close() after using ... (all the jdbc objects) You must close, to avoid errors, in reverse order as they were instantiated. Try it, i have no read your code and could be other problems. Hope this help Marcos -----Mensaje original----- De: Rudi Doku [mailto:[EMAIL PROTECTED] Enviado el: miércoles, 03 de marzo de 2004 10:04 Para: Tomcat Users List Asunto: OracleConnectionPoolDataSource creates too many connections Importancia: Alta Hi All, My web application is using up all connections after running for a while. It's quite obvious that I'm not using the connection pool as it was designed to be used. The only way I can get these connections back is by restarting the Tomcat. I have ojdbc14.jar in the following directories: $CATALINA_HOME/commons/lib directory & $CATALINA_HOME/webapps/<myWebApp>/WEB-INF/lib. This code creates my connection Pool ------------------------------------ private void createConnectionPool( ) { try { // Create a OracleConnectionPoolDataSource instance. connectionPoolDS = new OracleConnectionPoolDataSource( ); String url = "jdbc:oracle:thin:@194.26.151.17:1521:mosaic"; connectionPoolDS.setURL( url ); // Set the user name. connectionPoolDS.setUser("mosaicuser"); // Set the password. connectionPoolDS.setPassword("mosa1c"); } catch ( SQLException ex ) { // Catch SQL errors. //context.log( ex.toString( ) ); // log errors. } } This code creates a PooledConnection. ------------------------------------- public static synchronized PooledConnection getPooledConnection(){ try{ pooledconn = connectionPoolDS.getPooledConnection(); }catch(SQLException sqle){ sqle.printStackTrace(); } return pooledconn; } In my LoginServlet, I create a new PooledConnection, which I add to the Servlet Context: PooledConnection pc = ConnectionFactory.getInstance.getPooledConnection(); ServletContext ctx = getServletContext(); ctx.setAttribute("pooled_conn", pc); On an JSP Page: ServletContext ctx = getServletContext(); PooledConnection pc = (PooledConnection)ctx.getAttribute("pooled_conn"); Connection con = pc.getConnection //do a few things with the connection try{ if (con != null){ con.close(); } // I'm assumingthis returns the connection to the Pool }catch(SQLException sqle){ sqle.printStackTrace(); } Any help to solve this mystery would be very much appreciated.
