Cindy,

[Quoted] Thanks. I looked at the document. I'm not sure whether I have the thin or [Quoted] the OCI driver. I ran the following sample program:

import oracle.jdbc.driver.*;
import java.sql.*;

public class JDBCTest {

 public static void main(String[] argv) throws Exception, SQLException {   String dbURL = argv[0];
  System.out.println( dbURL );
  String username = "ucboulder";
  String password = "ucboulder";

  try {
   Class.forName("oracle.jdbc.driver.OracleDriver");
} catch (Exception e) {

   e.printStackTrace();
   throw new Exception("Cannot load Driver " + "oracle.jdbc.driver.OracleDriver");
}

  try {
   Connection conn = DriverManager.getConnection(dbURL, username, password);
} catch (SQLException e) {

   e.printStackTrace();
[Quoted]    throw new SQLException(e.getMessage());
}

 }
}

The results for both the thin and OCI drivers were:

---

java JDBCTest
jdbc:oracle:oci8:_at_(description=(address=(host=localhost)(protocol=tcp)(port= 1521))(connect_data=(sid=myp)))
jdbc:oracle:oci8:_at_(description=(address=(host=localhost)(protocol=tcp)(port= 1521))(connect_data=(sid=myp)))

[Quoted] which makes me believe I'm not running a thin driver. But I've no idea what to make of:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no ocijdbc8 in java.library.path

[Quoted] Any idea?
