Weblogic8.1sp3是否支持Oracle805?

Question

我在Weblogic8.1sp3上配置JDBC，远程数据库系统是Oracle8.0.5的，本机的Net8已装好，并已测试连接成功。可是通过Weblogic配置向导设置JDBC时，总是测试连接失败，不是报“Net8 protocol error”，就是“类型长度大于最大值”，看JDBC的驱动描述里最近的都是Oracle8.1.7，不知道Weblogic8.1sp3是否支持Oracle805？请大家帮忙指导一下，谢谢！

在Weblogic8.1sp3上连接Oracle8.0.5，在配置JDBC连接池时，测试总是失败，打电话去问，说是可能不支持低版本的Oracle，上网咨询也没有人答复，经过自己仔细查看有关文档，发现如下有关信息：
Using the Oracle Thin Driver
The 10g (10.1.0.2.0) version of the Oracle Thin driver (ojdbc14.jar) is installed in the WL_HOME\server\lib folder (where WL_HOME is the folder where WebLogic Server is installed) with weblogic.jar. The manifest in weblogic.jar lists this file so that it is loaded when weblogic.jar is loaded (when the server starts). Therefore, you do not need to add the Oracle Thin driver to your CLASSPATH.
Note: The ojdbc14.jar file replaces classes12.zip as the source for Oracle Thin driver classes. This version of the driver is for use with a Java 2 SDK version 1.4.
If you plan to use a different version of the driver, you must replace the ojdbc14.jar file in WL_HOME\server\lib with an updated version of the file from Oracle or add the new file to the front of your CLASSPATH. You can download driver updates from the Oracle Web site at http://otn.oracle.com/software/content.html.
Note: In WebLogic Server 8.1SP3, the default version of the Oracle Thin driver was changed to the 10g driver (the version in WL_HOME\server\lib). In previous releases of WebLogic Server 8.1, the 9.2.0 version of the Oracle Thin driver was the default version of the driver.
The WL_HOME\server\ext\jdbc\oracle folder (where WL_HOME is the folder where WebLogic Platform is installed) of your WebLogic Server installation includes subfolders for the 9.2.0 and 10g versions of the Oracle Thin driver. To use the 9.2.0 version of the driver, Follow these steps:
1. In Windows Explorer or a command shell, navigate to the WL_HOME\server\ext\jdbc\oracle\920 folder.
2. Copy ojdbc14.jar.
3. In Windows Explorer or a command shell, navigate to WL_HOME\server\lib and replace the existing version of ojdbc14.jar with the version you copied.
To revert to version 10g (the default), follow the instructions above, but copy from the following folder: WL_HOME\server\ext\jdbc\oracle\10g.
按照上面所述，把WL_HOME\server\ext\jdbc\oracle\920文件夹下的jdbc14.jar复制到WL_HOME\server\lib，然后不论在配置向导里还是在控制台下配置JDBC连接池，数据库选Oracle，Database Driver选“Oracle's Driver(Thin) Versions:8.1.7”，最后测试通过！
希望以上能对碰到同样问题的人有所帮助。
