Discussion Board for collaboration related to QlikView Deployment.
We just added a 2nd QVserver to our environment for the purpose of load balancing documents for users. We're using the native QV clustering and are not running IIS. We use the IE Plugin.
Server1 - QVS - QVWS - Management
Server2 - QVS
Server3 - QDS
Server1 and Server2 are setup to Cluster. Upon setup we found all was working except that some users were getting an error in IE referring to (iis_authenticate ..... QVSTunnel.dll%3Fhost%3DServer2)
We opened a case with QlikTech which at one point they had us add a "Link Machine Name" in the cluster setup. This stopped the user errors .... however now all users are connecting to server1. Even though in the web logs it shows a descision is being made to load balance to server2 the document is being loaded on server1.
Caviat: the name that we entered in for "Link Machine Name" is a DNS name that resolves to server1.
Ports are open and server1 and server2 respond on port 4747. We are not tunneling.
Solved! Go to Solution.
Thanks Dan. Here's the reference:
Thanks again. I just called QlikTech after over 24 hours of not hearing anything and found out that I'm not going to hear anything until Tuesday. So. I could not find any significant documentation on the Link Machine Name and what it does and how it works. Our servers and customers are all internal.
I don't think it applies in your case, at least what the documentation says is that it would be used for external users.
- The users having problems were always the same ones or was this more like a random issue? Did you make sure all the users were not going through a proxy to get to eiher qlikview server?
- Did you tried the same thing with ajax? were you getting problems there as well?
It's pretty consistant but not all users for some reason. There is no proxy involved. Interestingly if I choose Ajax zero footprint from the Access Point I do not have any trouble. I have updated my QlikTech case with this info.
The link machine name is used for the Plugin Client. It should be the FQN for the server.
Dan - We're using the DNS names. I would prefer to remove the Link Machine Name as the clustering works fine without this in my environment however I get the QVSTunnel.dll error when some clients connect the Server2.
Bill - Should it be the FQN for the Access Point or the QlikView Server?
