Session Lost when opening document (AJAX SR12)

Fri, 19 Feb 2016 10:40:34 GMT

Hello Community!

Recently we've been experiencing problems when attempting to open certain Looped&Reduced documents via Access Point. The document stays in a status of loading for about a minute, then an error message appears stating 'Session Lost'. To clarify, there are no problems encountered while loading the same distributed qvw via Desktop Client.

The distributed documents aren't that large in size (between 5 and 500MB), but do have a few macros triggered OnOpen. Has anyone who has experienced similar problems provide some insight as to the possible causes here?

Thanks,

James

Hi James,

OnOpen triggers aren't supported when using AJX, from the reference manual:

OnOpen

Select this event to assign an action to be executed each time the QlikView

document is opened. This event is not supported when running in the AJAX

client.

Hi Andrew,

Regardless of whether or not they are supported, they do work in AJAX client. We've been using them successfully in our documents for several years. I think the solution is more complex than this I'm afraid.

Thanks,

James

It could also be that the document is taking too long to open and the web server has timed out.

Try setting the <QvsTimeout> in the config.xml under your QlikView Web Server folder (C:\Documents and Settings\All Users\Application Data\QlikTech\QvWebServer\config.xml) to something larger.

We upped the timeout from 60 seconds to 600 seconds and this solved the issue - thanks very much!

Hi,

will this setting work, when we use an IIS?
