Reference for QlikView coredump dmp ctxf variables ?

[fredericvillemi]

Hello,

On my QlikView server I have frequent crashes mostly based on bad developement of Apps.

But I would be happy to be able to find some precise root causes based on .ctxf files.

Is there a reference somewhere for the structure of the ctxf files ?

Here is one below, I would be happy to have more details about how i can use it to find which element of the document is bad

Thanks

to do crash analysis we have to engage R&D, and they will not work with an unsupported version, please reference: https://community.qlik.com/t5/Product-Lifecycle/QlikView-Product-Lifecycle/ta-p/1826339

There are various measurements within Qlik to prevent server-crashes but they won't fetch each occurrence. Especially the server-objects and their storage within the shared-files is common cause for issues - which are not obvious by investigating the application with the desktop client.

For testing reasons you may remove the shared-file (after a BACKUP) and/or disabling server-objects and/or trying to repair the file (within the power tools are viewer and a repair-tool available).

Thanks for the link,

Unfortunately we have no immediate plans to migrate to a newer version .. 

And I understand no parameters of the  .ctxf are documented if only R&D can use them ..

Unfortunately, I have checked the settings and there are no server objects as we have denied them on this app. I have already seen that it may be the source of many issues.

I'll keep on testing this app.

I would look into the data-model and making sure that there are no synthetic keys and/or circular references. Further if there are any island-tables that they aren't used in the UI in an association against the normal data-model. Also reviewing all calculated dimensions - especially those with aggr() and the ones which aren't directly applied as object-dimension else anywhere in groups/labels/titles and so on.

Thanks for these tips, I will look at those items in the document, the (quite small) document usually works fine and I haven't seen mistakes for the moment but there is something bad somewhere 🙂
