HELP - JDBC to Oracle!

Question

We're doing Usage Pattern Simulation using LoadRunner. Our Oracle table has about 100 rows with 8 columns.
Our test includes <insert / select / update / select>. We run the test using 5 vUsers.
Interesting enough, insert & update works fine. However, we don't seem to get any concurreny on select.
What are we missing here? Any pointers?

System.out.println ("Loading Database driver...");
try {
     DriverManager.registerDriver ( new oracle.jdbc.driver.OracleDriver());
catch (Exception e) {}
try {
DriverManager.registerDriver ( new sun.jdbc.odbc.JdbcOdbcDriver() );
catch (Exception e2) {
System.err.println ("loadJDBCDriver: " + e2.toString());
return;
System.out.println ("Database driver loaded...");
private static Connection getConnected () {
System.out.println ("Establishing database connection...");
String jdbc_url;
Connection conn;
try {
jdbc_url = "jdbc:oracle:thin:@localhost:1521:oracle";
conn = DriverManager.getConnection (jdbc_url, "scott", "tiger");
catch (Exception e) {
try {
jdbc_url = "jdbc:odbc:BookNook";
conn = DriverManager.getConnection (jdbc_url);
catch (SQLException e2) {
System.err.println ("getConnected: " + e2.toString() );
return null;
System.out.println ("Database connection established ...");
return conn;
