Base Memory size is zero for most apps in QMC apps section

sebastiannord — Tue, 14 Nov 2023 14:50:25 GMT

Hi,

Since May 2023 there is a column in the apps section in QMC called "Base Memory size (MB)". The value is however zero for most apps, even if they have been reloaded multiple times.

What is needed for calculating "Base Memory size (MB)" for all apps?

This column is populated when the app is reloaded from the QMC.

The in-memory file size of the app. The value is updated when the app is reloaded.

The difference between this value and File size (MB) is that the base memory size also includes visualizations, bookmarks, measures, etc, from the QVF file.

I would say that all apps in my screenshot are reloaded on schedule. Do I have to reload them manually in QMC?

Exactly, that is why I am so interested in the in-memory file size of the app (which I am currently not getting for the majority of my apps, hence my question).

"The difference between this value and File size (MB) is that the base memory size also includes visualizations, bookmarks, measures, etc, from the QVF file."

I know that's what the doc says. But it does not match the numbers I see. The filesize matches the disk physical storage size when the app is exported. And base memory size is the memory size after the app is loaded to memory.

My apps loaded on-schedule do show a base memory value. Not sure what is different about yours.

Yes, that is really strange. I am trying to narrow it down. I doesn't seem to be related to:

App size on disk
App owner
Reloading node
Consumer node
If the reloading node differs from the consumer node

Could there be a limit for how big the app can be in memory for this to be calculated?

FYI, I have the same issue, all my tasks are triggered via EDX, you can see here a sample of some of them where base memory is updated or still to 0. This sounds a bit random.

Any news to this topic?

It would be interesting to know if this is working as designed (not calculated for larger apps), if it is a matter of configuration (QMC, settings files etc) or if it is a bug.

Any app modified by sa_scheduler is zero in our system. Not sure what that means.

Hi Everyone,

We had a similar issue with the our Qlik environment. It seemed that a Table in our Repo had gotten corrupt which was responsible for showing these values. We had to use certain PG cleaning scripts to get it back to normal.

Regards,

Rohan.

Rohan, how did you determine the corruption was the cause and where did you get the scripts?

Re: Base Memory size is zero for most apps in QMC apps section

Rohan — Sat, 20 Jan 2024 05:15:24 GMT

@Siciliani Our Repo backup that was getting generated was of minimal size, hardly in a few kbs. Then later we when connected with Qlik Support, then we came to know about the corruption issue & the commands were shared by support team. They have a certain generic commands for such scenarios to do a clean up.

Regards,

Rohan.

As everybody is said the base memory app size is the when the app is reloaded from QMC.

Now I have some queries related to this as you can see below is the screenshot of my app and its respective base memory size before reloading from QMC, so its size is showing 571.23 MB

Now, I have edit the app and removed every script and just put exit script, removed every bookmark, sheets and all as you can see below script, saved and reload its respective same task from QMC.

So, as people are saying base memory incudes bookmarks, visualization, data etc. then why it is still showing me base memory as 571.23 MB even after empty script, visualization etc. from the app.

Even though the doc says "the base memory size also includes visualizations, bookmarks, measures, etc, from the QVF file." I don't believe this is correct. I think the base memory size is only the tables and fields memory.

In your case, your exit script should have produced an app with no data model and therefore zero for size. I'm not sure why you don't see that reflected in the QMC. A page refresh issue perhaps?

Hey Rob,

Thanks for the clarification.

Even I was expecting the size should be zero, but not however I have tried refreshed qmc and clear cache memory as well.
