Expert Oracle Database Tips by Donald BurlesonDecember 23, 2015

Question: How do I test a JDBC connection to Oracle?

Answer:  Here is some sample Java code to test an Oracle JDBC connection:

import java.sql.*;

public class TestDBOracle {

public static void main(String[] args)
throws ClassNotFoundException, SQLException

// jdbc:oracle:thin:@//host:port/service    

String url = "jdbc:oracle:thin:@//myhost:1521/mydb";    

// Real Application Cluster database
String url =

Connection conn =

Statement stmt = conn.createStatement();
ResultSet rset =
stmt.executeQuery("select BANNER from SYS.V_$VERSION");
while ( {
System.out.println (rset.getString(1));

System.out.println ("Success!");
