Browser Timeout

Tue, 08 Jul 2014 08:39:07 GMT

Hi,

We have a "problem" with Internet Explorer, and that is - it seems as if IE has build in timeout of 1 minute.
Since a computation on server lasts more than 1 minute, the IE breaks connection to server, and the results are not delieverd to an end-user.

We tested this with other browsers as well - and the results ARE being delivered.

Since IE is a default browser in our company, we are trying to find a way how to increase a timeout in IE.

In "Internet Options" we haven't find this setting. Furthermore, we have also found similar settings on Server (QV). After changing this parameters, we have established that they do not change the timeout.

Did anyone previously have this problem? Can you please help me resolve it?

UPDATE: ok - it seems we have the same problem with Google Chrome. - so I changed the title.

Thanks!
D.

thx for the answer.

I have 2 questions in regard to them:

1) since we have established that it all functions as it should when we are using other browser (such as Google Chrome), how will the settings on server effect Internet Explorer

2) if I apply the suggested settings, do I have to restart all QV Services`?

Regards,

UPDATE: ok - it seems we have the same problem with Google Chrome.
I can't find the settings in the second picture inside Console. Where are they located?

Hi,

1) What version of Qlikview you use?

2) you need not to restart server.

Hi,

What the behaviour of IE after the timeout? Have you a message like "Lost connection to the server. Reconnecting..."?

Exactly that is the message I am getting: Lost connection to the server. Reconnecting..."?

Hi,

What I can see here is with SR6 you need to have IE 11.

There could be many things I can think of

1) It could be your network issue.

2) Same ID is used by two different people at the same time

3) Do you have Section access?

4) go to Settings--> Document Properties --> Server --> Find the "Maximum Inactive Session" Make sure that the value is fare enough.

5) lastly try by increasing timeout session here in the below path

C:\Documents and Settings\All Users\Application Data\QlikTech\QvWebServer\config.xml contains a line <QvsTimeout>60</QvsTimeout>

As Ashfaq said, are you sure that you are not sharing the same login with different users?

Or, have you build a cluster with a load balancer at the top? We add the same issue because the load balancer was sending people on different front end servers during the same session.

- I do not have Section Access in this app

- point 4: where do I find Settings?

- point 5: I can find this: C:\Documents and Settings\All Users\Application Data\QlikTech however this part I cannot find: QvWebServer\config.xml

Hi,

4) its your QlikView document. Open your QlikView document in QlikView desktop and follow above steps.

5) Try this C:\Documents and Settings\All Users\Application Data\QlikTech\WebServer\config.xml

4) it had no effect - behaviour stayed as it was

5) I can get to "Qlik Tech" folder. and than inside that folder I do not see "WebServer" folder. Moreover of the available folder there is no "config.xml" file.

Do you maybe have some other suggestion?

Regards,

Not sure what you think.

We are using Active directory groups for access.

There are no clusters in our architecture (one dev and one prod server)

Any other suggestion?

Hi,

You are on qlikview server right?

Can you post snapshot of QlikTech folder.

Regards

This message can happen when QV thinks that two users are using the same login. That's why I was asking for the cluster.

Have you this message only in prod or on both environments?

Re: Browser Timeout

Tue, 08 Jul 2014 11:57:19 GMT

Yes - I am getting the same message on prod server as well as on dev server.

I doubt it is login issue, because we are well aware that the processing we are testing is demanding - so it has to last more than 1 minute.

No idea what to try next...

Re: Browser Timeout

Tue, 08 Jul 2014 12:01:02 GMT

Yes - i am on QV server.

Not sure what to post, because we have circa 20 different users. Every user has QlikTech folder. In this folder there are 2 folders: "QlikView" and "QlikViewBatch". Inside both of them there are no any important files or the subfolders are completely empty.

Additionaly, I have checked QlikTech folder for my user as well as for QV Admin and QV service Users - same story...

Stupid question, but your dev server and your prod server are using different licence keys?

Re: Browser Timeout

Tue, 08 Jul 2014 12:08:25 GMT

of course
we already have circa 30 QV applications.

This message apprars to my knowledge only when we set certain selection criteria in one application.

Re: Browser Timeout

vincent_ardiet — Tue, 08 Jul 2014 12:17:31 GMT

Ah ok, it's only in one application?

We have the same kind of troubles with some cross tables when they becomes empty. If it's possible try to eliminate some objects on your page to identify the guilty one. We have also experimented some bugs like this with listboxes which were referencing deleted fields.

After QV becomes crasy with the application we have to clean the IE cache and to remove the last document state.
