Auto update data with binary load

prodanov — Fri, 25 Apr 2025 07:43:26 GMT

Hello, Gurus,

I have, but I think we all have or will have an issue with the new restriction on binary. On November 24, patch 7, Qlik forbids reading data from the automatically generated folder, which manages the created Qlik Sense Client Managed applications (\\<QlikSharedFolder>\Apps). They said this is a security vulnerability, but I can't find a solution for how to binary load data from another application.

I was trying to do this with the support team, but their solution is to export app into another folder, and then use load data with binary.

The nice thing is that Qlik still uses the old way in Qlik Cloud.

What is your opinion about that?

Regards, Dimitar

I don't understand why Qlik Sense client managed does not support Binary load by id as Qlik Cloud does.

Hi, Rob,

Do you check it?

I have not asked anyone at Qlik about this. Maybe someone from Qlik will weigh in here.

Can't you just create a data connection that points to the apps folder and do a binary load using that? The documentation doesn't describe any restrictions like the one you mention, nor does the release notes for nov24 patch 7.

@henrikalmen To my knowledge the apps folder is unreliable. My latest install of Qlik Sense with the new Postgres no longer stores anything in the Apps folder. Also, there were knowledge base articles in Support warning against using Apps die to file io collisions.

It seems I'm misunderstanding something. By "apps folder" I meant the one defined in QMC->Service Cluster->App folder, i.e. where QSEoW stores the binary files for qlik sense apps. Bút I haven't actually used binary load since QlikView, so I realise I'm probably not up to date with how these things works - but I assumed it would work something like this (that I found just now when googling this issue). Confusing though that it seems that Qlik hasn't announced a difference in how binary loads are handled, but @prodanov says Qlik support team confirmed it in a conversation.

Hi, @rwunderlich @henrikalmen , how are you doing in Qlik Sense On Premise environment solution like this: Data Model (updated every day) and many end user applications based on this Data Model?

Hi you can do binary load it's a "security feature" that Qlik added with the aforementioned patch. You can disable it in the engine's system.ini located C:\ProgramData\Qlik\Sense\Engine with

[Settings 7]
EnableQvfPathValidation=0

and restart services

I suppose it depends on what the data model looks like, but for me: I store transformed tables as qvd:s and load those qvd files into the apps that need them.

@henrikalmen I stand corrected. I was looking at the wrong folder.

Yes, you can, I know, but in the documentation, sad that it is not recommended, but it doesn't tell why.

Re: Auto update data with binary load

OK, it is possible, but this is not a data model; this will be a data transformation and will need new free space to store the data.

There are a lot of solutions to make a workaround, but why is this needed?

Hello,

This is the reason Qlik to removing the functionality of binary load from file created and update from the system 🙂

------------------------

Engine needs to read and write to the Apps continuously. As Engine takes various locks on the file this can cause issues with the normal usage of the App.

Having a binary load reading from that very same folder can cause:

- Source App not opening for users
- Binary reload to lock the source App from being modified until reload is finished
- Binary reload to fail, due to changes to source App are made while reading the source App.

This improvement was done, as we have had lot of issues previously with customers complaining on file locks not releasing or changes not being applied on their apps, all this due to binary reloads reading from the Apps-folder.

---------------------------------------

We can't find a solution, and you have a binary; there is an issue, you don't have a binary, there is no issue.

Dimitar
