Oracle 11g向后兼容与较早的Oracle版本 [英] Oracle 11g Backward compatibility with older oracle releases

问题描述

我们的组织计划升级其大多数oracle服务器和服务器.客户端使用11g第2版.

Our organization is planning to upgrade its most of the oracle servers & clients to 11g Release 2.

但是我们的客户端系统之一仍在使用oracle 8i安装.

But one of our client system is still using oracle 8i installation.

我们可以从oracle 11g客户端访问Oracle 8i的对象吗?

Can we able to access the objects of Oracle 8i from oracle 11g client?

一些博客说它应该工作，而另一些说它不行.

Some blogs says that it should work and other say it won't.

任何人都可以在这种配置上遇到任何问题.

Can anybody faced any issue with such configuration.

一位高级dba告诉我们oracle仅支持2个早期版本到当前版本的向后兼容性.假定这一事实，我们就不能访问在oracle 8版本上运行的数据库对象.

One of the senior dba told us that oracle only supports backward compatibility of 2 versions earlier to current version. Assuming this fact we shouldn't been able to access database objects running on oracle version 8.

请帮助.

谢谢.

推荐答案

为了连接到Oracle 8数据库，我们不得不恢复到Oracle 10客户端(我相信是10.1).如果有一种方法可以使用11.2，我想接受教育.

We had to revert to Oracle 10 client (10.1, I believe) in order to connect to an Oracle 8 database. If there is a way to do it using 11.2, I'd like to be schooled.

编辑:10.2将正常运行.这是官方用语:

10.2 will work. Here's the official word:

访问Oracle数据库服务器(Oracle8i版本3或更高版本)"

"Access to an Oracle Database Server (Oracle8i Release 3 or later)"

从11.1开始，您不走运:

And as of 11.1, you're out of luck:

访问Oracle数据库服务器(Oracle9i版本2或更高版本)"

"Access to an Oracle Database Server (Oracle9i Release 2 or later)"
