Morten and Halvdan,

 

Thanks for your responses thus far. I will consult our server specialist for 
input/clarification as I am kind of floundering in the dark here.

As Morten says, the files should be stored under '$DHIS2_HOME/documents'. There 
is no intent to store them in the WAR file itself for production instances. 
That would be pretty silly. It might be a fallback though (which is probably in 
place for testing purposes).

 

In answering your comments on where and how the files are stored: 

This is a pretty classic problem in database design. And there certainly is no 
'correct' way to do it. We've elected to keep large binary files out of the DB 
to avoid bloat (it's already huge for many DHIS 2 instances). 

 

Most importantly, storing large files in the DB can incur huge storage costs 
for instances running off of SSDs. Serving files can in those cases be done 
from a separate (much cheaper) disk or location, which makes a lot of sense. Of 
course, this has some major drawbacks as well, especially in terms of adding to 
maintenance complexity. It's a tradeoff.

The problem is that you add those documents to a dashboard and if you update 
the war file they no longer available… best not to have an option to share 
resources then if you need to reload them every time…

 

I do understand that DHIS2 has the ability to store files but the use in this 
case is for example to add manuals or SOPS or guidelines to the system so the 
file storage is not ideal rather chose to use resources since it is available 
in DHIS2. We also using it to load user access forms which may not be intended 
usage but is useful and the reality is that every time the war is updated 
everything that is uploaded is destroyed – quite a shock…

 

I must also say that the documentation does not provide clear guideline on how 
this feature should be used and a warning that anything you load there is 
stored in the war file?

Re: [Dhis2-devs] Question about uploading resources into DHIS2

[Morten Olav Hansen]

Hi Elmarie

Just tried this, and in my case they are ending up in
$DHIS2_HOME/documents, what is your home set to? are you sure the
application can access that folder?

[Dhis2-devs] Question about uploading resources into DHIS2

[Elmarie Claasen]

Hi all,

 

>From what I am told whatever resources you load into DHIS under Reports >
Resources and whether you add them to a dashboard those are stored in a
subfolder in the war file folder on the server. When the war is updated all
those files are destroyed and thus you don't have those copies anymore. Any
reason why those resources are stored in the war file folder and not in the
same location as uploaded files on the dhis2_home or even better in the
database itself?

 

The problem is that you add those documents to a dashboard and if you update
the war file they no longer available. best not to have an option to share
resources then if you need to reload them every time.

 

I do understand that DHIS2 has the ability to store files but the use in
this case is for example to add manuals or SOPS or guidelines to the system
so the file storage is not ideal rather chose to use resources since it is
available in DHIS2. We also using it to load user access forms which may not
be intended usage but is useful and the reality is that every time the war
is updated everything that is uploaded is destroyed - quite a shock.

 

I must also say that the documentation does not provide clear guideline on
how this feature should be used and a warning that anything you load there
is stored in the war file?
