Question

我想使用 ojdbc6 驱动程序通过jdbc连接到Oracle数据库。

我在虚拟机中安装了Oracle 10g，而Oracle 8i正在运行。我试图创建一个允许我连接到数据库并执行一些SQL语句的java应用程序。

使用 Oracle 10g ，一切都正常，但与 oracle 8i（8.1.7）我得到错误

这一堆栈跟踪（jdbcon是我的类名）

at jdbcon$4.actionPerformed(jdbcon.java:235)

带我到这行代码

con=DriverManager.getConnection("jdbc:oracle:thin:@"+adresse+":"+port+":"+bd,user,pass);

源代码

    try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
             con=DriverManager.getConnection("jdbc:oracle:thin:@"+adresse+":"+port+":"+bd,user,pass);
                if(con.isValid(10))
                    //System.out.println("Connexion réussie");
                    JOptionPane.showMessageDialog(null, "Connexion réussie");

注意

当我使用错误的 SID 时，它会给我这个错误：

java.sql.SQLException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

这意味着主机端口没问题。当我使用正确的SID 时，我得到了上一个错误。

此问题仅适用于 oracle 8i 。

Answer 1

ojdbc6和ojdbc5驱动程序不支持Oracle版本8（这些版本适用于oracle的更高版本），您需要连接：

可以从Oracle8i JDBC Drivers

下载的

classes12.zip个驱动程序

Answer 2

你显然需要一个用于oracle8i的jdbc驱动程序，因为oracle10g和oracle8i不能使用相同的驱动程序

使用ojdbc6驱动程序通过jdbc连接到Oracle 8i数据库时出错
