Application Time out

#1

Postby xren » Thu Nov 26, 2015 2:57 pm

Hi,

User asked for longer time out period.
I set the web.xml session time out to unlimited -1

However, user still experience time out. How this happen and how can I resolve this issue?

Thanks,
Xiaoli

Hi,

Rather than increasing the global timeout we have some logic so an individual form essentially never times out as it interacts with the server on behalf of the user.

Maybe this is of use?

Hi Steve,

I would like to know the reasons that a form times out after the global session time out been set to -1.

I think it is not per form time out, it is more like application level. After a while after a open a form without working on it, then when I click on the form, the browser goes to time out page:

"Application Timeout"
"The application has timed out."

Does your solution on the other thread solve this problem? I have many forms, it will be preferable that I can have a global time out control.

Regards,
Xiaoli

Hi, we've never looked at a limitless global timeout so I can't comment there.

We deliberately went down the per form timeout control. We have many forms that are quickly concluded and a high volume. We have a low proportion of forms that take longer to complete.

We found that increasing the global timeout meant excessive memory usage, especially as at the time we were running Windows 2003 so were limited on maximum memory allocation.

Tried to set this in version 5.0.0 by setting to -1 and the session appears to hang the page after 30 minutes.
If I resubmit from the developer (ebase), the session appears as still being active since user showed as logged in.

Path: C:\..\EbaseXi_5_0_beta\UfsClient\IntegratedServer\ebasetest\WEB-INF


server log once I try to interact with page after 30 minutes

Code: Select all
