我没玩过Publisher，研究的也不多，关于你这个答案我不能给你很好的答案，看看其他高手有没有好的建议。
不过我找到了这篇文章，应该对你有所帮助。

问题：
I'm new to Qlikview. I'm currently working with a client with Clustered environment. I the environment has been setup and working fine for quite sometime now.
There are currently 3 servers, one is publisher, Master web server and slave web server. I wanted to identify which server does the publisher jobs and which server is the master. Below are the details furnished:
Server A has the following services running: QlikView Directory Service Connector QlikView Server QlikView Management Service QlikView Publisher Command Center Service QlikView WebServer
Server B has the following services running: QlikView Management Service QlikView Server QlikView WebServer QlikView Distribution Service
Server C has the following services running: QlikView Distribution Service QlikView Management Service.
Please help me in identifying the Publisher Server and Master Server in the environment.
 
 
答案：
It's hard to tell for sure because there are a few possible setups you can have with what you described. I would guess though that Server A is your cluster master server (i.e. the cluster is configured in the QEMC of Server A). Server B is most likely the cluster slave node. As a rule of thumb, I usually assume that whichever server has more tasks running is the master. But of course that is not always the case.
Either Server B or Server C handles Publisher tasks, because those are the only servers where Distribution Service is running. You might also have a either a dual or a clustered Publisher environment, in which case both Server B and C are Publishing.

可以的，首先请参考权限管控这一章节的内容，http://www.hellobi.com/course/33的第七课时。
在你了解了以上知识以后，最常用最简单的办法就是将这两个字段进行拼接，组成一个新字段，然后利用该字段进行权限管控。

这个可以是真的。

是的，可以这么理解。QVD文件是QV的数据源，重新加载的过程相当于写入QVW的过程，前提是没有Drop table，服务器最后再把数据读取进内存。
