I have an app1 whose job is just to create a QVD file
Then an other app2 load from this QVD
when I try to load the app2 it says that is not possible to read the QVD file
indeed If I look in the directory where the QVD is store I don't see the file, only one day later it show up
The stange things is that if I load the QVD file with the app1 it loads with no error it is as if it was reading from a cache file and not from the QVD
Reading similar thread I tried to set sleep(9000) after the store but with not result, the QVD is not big around 30000 row
Hi David, thanks for replying
this is the APP1
load * ;
from FOLLOW_V ;
store FOLLOW_UP into 'lib://QVD (e_camerin)/FOLLOW_UP.qvd' ;
from [lib://QVD (e_camerin)/FOLLOW_UP.qvd]
before loading APP 2 I closes app1
The following error occurred:
If the error is like following
Error: Cannot open file: 'lib://QVD Warehouse/NEW_DB_EnergyDataL5_converted.qvd' (Native Path: *** 2018-11-29 23:38:05 System error: ***)
Than it is deffinitely because of another app is using this QVD (loading or saving). Try also to remove sleep statement which I thing could cause troubles as well (it freeze app) and I don't see a reason for it.
Are you using QS Enterprise or Desktop? Could someone else use it? Can you see stored file in folder where you want it to have?
I'm using QS enterprise June 2018
If I edit the connection I can see the QVD, but if I look in the folder I can't, at least they show up only sometime and I don't understand in which circumstance.
I removed the sleep but the problem remain.
No other app is opening or loading from this QVD
I am really sorry but it is very difficult to tell what is wrong such remotely. I never experienced something like what you are describing.
Only one advice what can I provide is to 1) create new app and connection from scratch 2) reinstal Qlik
or maybe reinstal Windows...
