QVS Cluster Issue
Daniel Rozental May 24, 2012 3:29 PM (in response to Mark Ellis)Can you check the QVWS config file and see if both servers are being referenced there?

QVS Cluster Issue
Daniel Rozental May 25, 2012 11:37 AM (in response to Mark Ellis)Both servers should point to different locations not to the same, I think you should insist with support.

QVS Cluster Issue
Mark Ellis May 25, 2012 12:07 PM (in response to Daniel Rozental )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.

QVS Cluster Issue
Daniel Rozental May 25, 2012 12:54 PM (in response to Mark Ellis)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?

QVS Cluster Issue
Mark Ellis May 29, 2012 9:49 AM (in response to Daniel Rozental )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.

Daniel Rozental May 29, 2012 10:19 AM (in response to Mark Ellis)Are you using DNS names or IP Addresses? you should try changing that.

Bill Britt May 29, 2012 10:25 AM (in response to Mark Ellis)The link machine name is used for the Plugin Client. It should be the FQN for the server.

QVS Cluster Issue
Mark Ellis May 29, 2012 10:54 AM (in response to Bill Britt )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?

QVS Cluster Issue
Daniel Rozental May 29, 2012 10:58 AM (in response to Mark Ellis)Maybe some of the users have a firewall blocking the 4747 port for accessing Server2. Have you checked that?

Re: QVS Cluster Issue
Bill Britt May 29, 2012 11:27 AM (in response to Mark Ellis)The plugin client talks to the server on port 4747. So once you click a link in the accesspoint to open the document in plugin, it needs a way to get back to the server. Most of the time it is the same as the AccessPoint.
Another thing you can try is just putting
FromRequest
in the link machine name.

QVS Cluster Issue
Mark Ellis May 29, 2012 11:38 AM (in response to Bill Britt )OK makes sense. The DNS name we have in Link Machine Name is a name we have resolving to the Access Point server. Can you explain what putting "FromRequest" in for the Link Machine Name would do? Thanks.

QVS Cluster Issue
Bill Britt May 29, 2012 12:15 PM (in response to Mark Ellis)It is some old code that is still used. What it does it looks at the URL the request came from and that is what it uses for the link machine name. If you can find an old version 9 manual you will find it in there.
Link Machine Name
If your QlikView Server cluster is not exposed outward
with the same name as is used internally, you must enter
your external name here in order for the QlikView Plug-in
and the QlikView Java clients to work.
If left empty, the name exposed for the clients will be the
computer name of the QlikView Server.
To mimic the behavior of version 8.5, you can enter
(FromRequest) here. The name exposed outward will
then be the same as the url the client uses to connect to the
AccessPoint, that is the setting is taken from the request
coming from the client.

QVS Cluster Issue
Mark Ellis May 29, 2012 12:19 PM (in response to Bill Britt )Thanks for the info. I tried "FromRequest" and it didn't help. I also tried another QV plugin as things seem to be pointing there but to no avail as well. I have a call scheduled with QlikTech shortly and will report back the results. Thanks.

Re: QVS Cluster Issue
Adam Vaughan May 29, 2012 11:22 AM (in response to Mark Ellis)We found that with some of our clients this error crops up when people are making the documents a Favourite in IE, using the URL as shown when you open a document.
I'll have to aska colleague about the solution. You might find the favourites are causing an issue for you too.
Also, re: the cluster. Depending how you set the balancing to work, users may never see server 2 (unless you do round robin)

QVS Cluster Issue
Mark Ellis May 30, 2012 1:59 PM (in response to Mark Ellis)Issue resolved by adding the 2nd server in the cluster to Trusted Sites. See MS KB934366

Re: QVS Cluster Issue
David Strudwick Sep 13, 2012 7:25 AM (in response to Mark Ellis)Hi
We are experiencing a smilar issue on our clustered environment running QV11 SR1. Can you expand on what your solution was? Did you need to add the second server to the Trusted Sites on every users machines or on the server itself?
Also we have found that even when we set a document to be available only on one of the nodes (through User Documents --> ... --> Document Available = Never), QlikView ignores this option and will still load the document here anyway. I just wondered if you might have experienced this same issue?
Thanks
David

Re: QVS Cluster Issue
Mark Ellis Oct 3, 2012 11:09 AM (in response to David Strudwick)Trusted sites needs to be added on all client machines. We did this via system policy. We don't limit a specific document to a specific server so have not experienced that problem.
