Dear knut,

 

We can’t partitioning our instance into two because of requesting, but I’m 
planning to use multi DHIS2 databases and link it with one database, or I’ll 
start with new building to Database and DHIS2 by 2017, but all of these 
solutions will not fix the problem, because unit now I don’t know what does it 
appear from.

Note: for many times this problem fixed by itself I just change tomcat version, 
do maintain or update java but after restart server this problem return that’s 
makes it strange! 

I thing this problem came from categoryoptionbombo because I had to remove some 
from DB and I added other and sometimes we forced to add new category to old 
category combination, so these table huge and I can’t control them, how to 
rebuild it without losing data, I tried to remove categoryoptioncombo that are 
not in _catergorycomboname but it have data! And by remove it analytic stop in 
first step and after few hours program and apps stop working no think work 
except the login form.

 

Regards,

 

Abdulkarim,

Probably not very constructive, but would there be a straightforward way of 
partitioning your instance into two (as a worst case solution)?

Dears,
Actually we have a lot of data sets that need different category combination 
(attribute), because we need to use filter in reporting (data visualizer, pivot 
table) to multi data elements so reliance on event forms (programs) can't be 
useful for project like POLIO, AIRI that we work on,

and we use it for programs that need tracking like health information system 
and community health programs
so we have too much categoryoptioncombo,

also we have in one program over than 1300 dataelement 500 of them in multi 
stages that make this program huge, I faced a problem because of this (more 
than 1600 column in PostgreSQL) and I fixed it, but analytics after that take 
more time. however analytic period problem happen before that.

Actually I don't know what to do!

Regadrs,
Abdul karim,

That's a good point, Jason: a few months ago we tried under a similar hardware 
setting to run the system with around 350.000 categoryOptionCombinations.
Although it was possible to create all of the combinations (keeping the process 
alive for 5 days), DHIS2 started to behave funny in a lot of ways (analytics 
worked, though).

Better try to split your categories into categoryOptionCombinations and 
attributeOptionCombinations. categories where you might add new options go into 
categoryOptionCombinations, categories which will certainly not change (e.g.
age, gender) go into attributeOptionCombinations. That way you split the 
possible combinations into two chunks. I our example we have 52,800 
categoryOptionCombinations and 64,800 attributeOptionCombinations (which runs 
without a problem), where we'd theoretically have over 3 billion combinations 
if they were combined.

For our next data-cube we might try using anonymous events for these data, as 
Jason suggested, which might get rid of the problem of pre-defind 
cat-combinations.
