QlikView Document Reloading

Wed, 25 Nov 2020 16:16:04 GMT

Good day,

I am new to QlikView and have been asked to investigate why a QlikView document / model gives a Unexpected Exception error. (See attached screenshot)

The model is set to reload every 30 minutes and I think this happens when the reload is in progress and a user tries to access it.

Does this sound plausible, and if so, how should one go about doing such "real-time" model reloads keeping in mind that a user(s) might be working with the model at the time?

Secondly, the 30 minute interval / schedule looks to be a result of the developer not knowing when the data has been updated.

Apart from the scheduling technique, is there a way to externally / programatically / etc. trigger a reload via a process outside of QlikView? (This way we can only trigger a reload as and when data changes instead of the every 30 minutes polling approach)

Thanks in advance

Neil

No screenshot seen here. Can't tell if you are getting the error in the reload or on the user session.

QV reload expects that a user may be in session with the document. There are several refresh options available on how to handle an updated document. See the Help for "graceful refresh" Document Properties: Server ‒ QlikView

You can trigger a reload externally such as when an external process is complete. The feature is called "EDX" and it documented here Using EDX in QlikView 11

Thanks for the reply, those links seem to hit the spot.

I've attached the screenshot here now. It is on the user session.E.g.

Check the QVS Event*.log on the Qlikview server for an error message at the same time. The default log location is:

C:\ProgramData\QlikTech\QlikViewServer
