sudo: /etc/sudoers is mode 0640, should be 0440

If you encounter the following error, it is likely because you ran the su command while your current folder is /etc and the sudo is in the same folder.

Retrieving JDBC version information

The following is how you can retrieve the jdbc version:

import oracle.jdbc.OracleConnection;

import oracle.jdbc.pool.OracleDataSource;

import java.sql.SQLException;

import java.sql.DatabaseMetaData;

import java.util.Properties;

 

 

public class JDBCVersionInfo {

   

  public static void main(String[] args) {

    try {

      // Set up user connection properties

      Properties prop = new Properties();

      prop.setProperty("user","hr");

      prop.setProperty("password","password");

       

      // open the connection

      OracleDataSource ods = new OracleDataSource();

      ods.setConnectionProperties(prop);

      ods.setURL("jdbc:oracle:thin:@//prod:1521/proddb");

      OracleConnection ocon = (OracleConnection)ods.getConnection();

       

      DatabaseMetaData dbmd = ocon.getMetaData();

       

      System.out.println("Driver Name: " + dbmd.getDriverName());

      System.out.println("Driver Version: " + dbmd.getDriverVersion());

     

       

    } catch(SQLException e) {

      System.out.println(e.getMessage());

    }

  }

}
