更改会话中的映射
我的 Informatica 会话链接到错误的映射。 如何在同一会话 S1 和工作流 W1 中更改从 M1 到 M2 的映射，而不导入/导出为 XML 并进行更改？？？
I have a Informatica session which is linked to a wrong mapping.
How do i change the mapping from M1 to M2 in the same session S1 and Workflow W1 WITHOUT importing/exporting as XML and making the changes ???

暂时使当前映射无效并刷新会话。这将允许您为您的会话选择不同的映射。选择新的。
不要忘记验证您的旧映射。

Invalidate the current mapping temporarily and refresh the session. This would allow you to choose a different mapping for your session. Pick the new one.
Don't forget to validate your old mapping.

XML 导入/导出是执行此操作的唯一“官方”方法。如果您不想这样做，则必须创建一个新会话 S2 并将映射 M2 附加到该会话。
一个可能的额外选项（附带免责声明）：如果您有权访问 Informatica 的 Oracle 数据库（保存元数据），您也许可以直接在那里进行此更改。但您确实必须知道自己在做什么，否则很可能会把事情搞得一团糟。这当然不是推荐的更改方式！
XML import/export is the only "official" way to do this. If you don't want to do that, you will have to create a new session S2 and attach the mapping M2 to that session.
One possible extra option, with disclaimer: If you have access to Informatica's Oracle database (that holds the metadata), you could perhaps make this change directly there. But you would really have to know what you're doing, or else you are likely to mess things up pretty badly. This is certainly not the recommended way of making changes!
Informatica 元数据表让您感到困惑，不要在该级别进行更改。所有方法都是通过删除端口或语法错误使映射无效。 Workflw 询问您新的映射。这是最好的区别。 Informatica 应该添加新功能来允许我们做到这一点。
The informatica metadata tables confuses you , dont change at that level. All the way is invalidate the mapping by removing port or by syntax errors. Workflw asks you new mapping. This is the best way apart all. Informatica should add new feature to allow us to do this.
XML导出是最好的方法之一。
导出会话对象，然后编辑需要更改映射名称的 xml 文件。现在，当您导入它时，它会询问要关联的映射。
这样你就可以做到。
XML export is one of the best way.
Export the session object and then edit the xml file where you need to change the mapping name. Now when you'd import it, it'll ask for the mapping to associate with.
This way you can do it.
