Re: Problem creating datamart

 

Hi Hannan,

You configuration may have worked previously, but some things were
changed in the datamart and you will need to allocate more memory to
it after 2.7.

The details are here of the server setup are here

http://dhis2.org/doc/snapshot/en/implementer/html/ch08.html#d5e413

and the important part is the JAVA_OPTS environment variable, for instance...

export JAVA_OPTS='-Xmx6000m -Xms3000m -XX:MaxPermSize=800m -XX:PermSize=400m'

I am not really sure what your settings are, but you should at least
specify these options, of course adjusting them for the amount of
memory which can be allocated to DHIS2 .

Best regards,
Jason
