Question

我想用java连接到Oracle 8i数据库，其中数据库位于本地网络服务器10.3.1.1端口

我已按照示例教程从Oracle网站

建立连接

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

我也遵循了这里指定的指令 https://people.cs.pitt.edu/~chang/156/06oracle/jdbc.html

您可能需要以下详细信息：

Oracle 8i数据库端口1521
在Windows Server 2003上运行的本地网络服务器ip 10.3.1.1
在IP 10.3.1.2上的机器上的Java版本“1.8.0_152”
添加了classes12.zip文件来构建路径

这是我的Java代码：

draft3

我收到此错误消息：

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();
            }
        }

    }

}

我在互联网上寻找解决方案，但没有任何与我合作

这些是我的测试和结果：

使用错误的数据库名称（SID）进行测试

我已经测试过更改dabase名称（sid）的名称是否错误，以检查它是否已连接，谢天谢地，似乎与oracle的连接几乎正确，因为它会响应此错误

检查数据库侦听器

我已经与管理员核对了监听器状态，并且它正在运行（系统正在运行）

禁用防火墙

我已禁用防火墙

我在虚拟基础架构上安装了一个测试站点。

服务器：Windows 2003 SP2 32位
服务器：Oracle 8.1.7.0
客户端：Windows 7 32位
客户端：java 1.8.0_73
客户端：Oracle客户端9.2.0.1
客户端：Oracle客户端9.2.0.1中的classes12.jar，位于C：\ oracle \ ora92 \ jdbc \ lib

使用不同版本的jdbc驱动程序进行测试：

来自Oracle Server 8.1.7.0的classes12.zip，目录为C：\ oracle \ ora81 \ jdbc \ lib
来自Oracle客户端9.2.0.1的classes12.jar，位于C：\ oracle \ ora92 \ jdbc \ lib

http://download.oracle.com/otn/utilities_drivers/jdbc/121020/ojdbc7.jar
http://download.oracle.com/otn/utilities_drivers/jdbc/122010/ojdbc8.jar

使用不同的connectString进行测试：

connectString ="jdbc:oracle:thin:@10.89.251.123:1521:ORCL";
connectString ="jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.89.251.123)(PORT=1521))(CONNECT_DATA=(SID=ORCL)))";
connectString = "jdbc:oracle:oci:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.89.251.123)(PORT=1521))(CONNECT_DATA=(SID=ORCL)))";
connectString = "jdbc:oracle:oci:@ORCL8";

测试从Oracle Client 9.2.0.1连接到DB 8.1.7.0 SID = ORCL

这是您的Java代码：（瘦jdbc-＆gt; oracle服务器）

    public DBConnect() {

        connectString = "jdbc:oracle:thin:@10.89.251.123:1521:ORCL";
        System.out.println("Before DriverManager.getConnection");
        try {
            connection = DriverManager.getConnection(connectString, "scott", "tiger");
            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();
        }
    }

}

}

测试连接成功!!!

C:\Program Files\Java\jdk1.8.0_73\bin>javac.exe  DBConnect.java


C:\Program Files\Java\jdk1.8.0_73\bin>java -classpath  . DBConnect

在Oracle Server上的文件listener.log文件中记录连接c：\ oracle \ ora81 \ network \ log \ listener.log

将瘦驱动程序更改为oci（jdbc-＆gt; oracle客户端库 - > oracle服务器）

public void connect() throws Exception {
    String connectString;
    Class.forName("oracle.jdbc.driver.OracleDriver");
    connectString = "jdbc:oracle:oci:@ORCL8";
    System.out.println("Before DriverManager.getConnection");
    try {
        connection = DriverManager.getConnection(connectString, "scott", "tiger");
        System.out.println("Connection established");

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

}

我继续使用不同版本的jdbc驱动程序进行测试。 http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html
