如何在本地网络上将Java与oracle 8i数据库连接

[英]How to connect Java with oracle 8i database on local network

 原文  2017-12-25 07:26:35  5   1    java/ oracle/ jdbc/ oracle8i

问题描述

I want to connect to Oracle 8i Database with java, where the database is on server on local network 10.3.1.1 at port 我想使用Java连接到Oracle 8i数据库，其中该数据库位于端口10.3.1.1的本地网络上的服务器上

I have followed the example tutorial to make the connection from Oracle website 我按照示例教程进行了从Oracle网站的连接

https://docs.oracle.com/html/A67296_01/im_examp.htm#997347 https://docs.oracle.com/html/A67296_01/im_examp.htm#997347

also I followed the instruction that specified here https://people.cs.pitt.edu/~chang/156/06oracle/jdbc.html 我也遵循这里指定的指令https://people.cs.pitt.edu/~chang/156/06oracle/jdbc.html

You may need these details : 您可能需要以下详细信息：

  • Oracle 8i Database port 1521 Oracle 8i数据库端口1521
  • Local Network Server Running on Windows Server 2003 ip 10.3.1.1 在Windows Server 2003 ip 10.3.1.1上运行的本地网络服务器
  • java version "1.8.0_152" on machine on IP 10.3.1.2 IP 10.3.1.2上的机器上的Java版本“ 1.8.0_152”
  • added classes12.zip file to build path 添加了classes12.zip文件以构建路径

This my Java Code: 这是我的Java代码： 

package com.oracle8i.testconnect;

import java.sql.Connection;
import java.sql.DriverManager;

public class DBConnect {
    public Connection connection;

    public DBConnect() {
        // TODO Auto-generated constructor stub
    }

    public void connect() throws Exception {
        String connectString;
        Class.forName("oracle.jdbc.driver.OracleDriver");
        connectString = "jdbc:oracle:thin:@10.3.1.1:1521:dbname";
        System.out.println("Before DriverManager.getConnection");
        try {
            connection = DriverManager.getConnection(connectString, "username", "password");
            System.out.println("Connection established");

            connection.setAutoCommit(false);
        } catch (Exception e) {
            // TODO: handle exception
            System.out.println("Exception inside connect(): " + e);
            e.printStackTrace();
        }

    }

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        DBConnect client = new DBConnect();

        System.out.println("beginning");
        try {
            client.connect();
            System.out.println("after Connected");

            client.connection.close();

            System.out.println("after close");

        } catch (Exception e) {
            // TODO: handle exception
            try {
                System.out.println("Exception : " + e);
                client.connection.close();
                e.printStackTrace();
            } catch (Exception ex) {
                // TODO: handle exception
                System.out.println("Close Connection Exception : " + ex);
                ex.printStackTrace();
            }
        }

    }

}

I get this error message: 我收到此错误消息：

These are my testing and results: 这些是我的测试和结果：

  • Testing with wrong database name(SID) 使用错误的数据库名称（SID）测试

I have tested changing the dabase name (sid) with wrong name to check if its connected or not and thankfully it seems the connection to oracle almost correct because it response this error 我已经测试过使用错误的名称更改dabase名称（sid），以检查其是否已连接，并且幸运的是，与oracle的连接似乎几乎正确，因为它响应了此错误
