JDBC Usage - Managing Connections

Question

Hi:
I'm not a Java Guru, I'm a rookie... so here it goes:
For developing my JSP apps to generate XML to my wireless apps I use this kind of instructions:
Class.forName("oracle.jdbc.driver.OracleDriver");
String url_qry = "jdbc:oracle:thin:@193.136.231.151:1521:neo";
String query_qry = "";
query_qry = "select * from clientes where cod_cliente = 1"
Connection conn_qry = DriverManager.getConnection(url_qry, p_username, p_password);
Statement stmt_qry = conn_qry.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
ResultSet rset_qry = stmt_qry.executeQuery(query_qry);
rset_qry.absolute( 1 );
%>
.... my xml or html
<%
     rset_qry.close();
     stmt_qry.close();
     conn_qry.close();
%>
My question is... Why my OC4J container shows always a high number of connections and the number of connections never shrink? I'm the only user to use these apps. So, Even if I use the close() methods the JDBC Usage in OC4J shows always growing numbers and never shrink...
Thanks

Hi Joao,
This is only a guess, but OC4J uses a database connection pool, so this is probably why you are seeing a large number of connections.
You can configure the size of the OC4J connection pool.
Have you read the OC4J documentation, or tried asking this question in the OC4J forum, or looked at the code samples from the "Technet" Web site?

Hope this helps you.
Good Luck,
Avi.
