This is very easy to do, and should even make the application more
lightweight for weaker hardware (do you know anything about the HW, Olav?),
but must of course be thought through and tested so that vital functionality
is not left out - and also not possible to "restore" (by changing user
access rights).

I do agree with this, and not really recommending it - should perhaps even
not have mentioned it as a possibility. The great advantage of Linux
(probably installed on a hard drive) is that it's less prone to virii
(usually propagated by USB sticks in such an unconnected environment). If
that is not feasible, perhaps the machines should dual boot: A stripped down
Linux partition for DHIS2, Windows for everything else they are doing
(mostly Word and Excel, perhaps?)

Indeed - the lack of tool support counts against H2 - though the tools
available for Postgres may also require extensive training to be used by
anyone. So I agree very much with any kind of super simple administrative
support that could be made readily available - no matter the choice of db.

And I thought I was the draconian one :-)  Still if its only a matter
of removing some modules from a custom pom it could be worth looking
at.  Olav maybe you want to try and see how it looks.

I'm not too convinced by the usb stick idea.  Not that its not doable.
 And I think its probably great for demos (WHO-on-a-stick) but in
real-life I don't think these sticks are well suited for database
read-writes.

One of the issues people do tend to have with h2 is a lack of
supporting tools to diagnose when things go wrong.  And I'd hate to be
on the phone to someone stepping through openoffice+jdbc setup or the
like.  If I were to ship h2 into the darkness of many remote districts
I think I would write a couple of really simple and small diagnostic
tools to test the integrity and health of the database and ship that
too.  Just the "where there is no doctor" common sorts of faults.
Then when I get the call "help!  my dhis2-ultra-lite doesn't work",
I'd ask them to run the diagnostic tool and read out the diagnosis
over the phone to quickly figure out if the h2 file is corrupted, or
metadata is misconfigured or what have you.  Planning for 170 offline
installs (or some reasonable proportion of that number) is no picnic.
The more work up front to make those calls easier the better.

I would recommend being quite draconian and pretty much disable the whole
Maintenance menu and quite a bit of the services menu as well. And then
train them really well on the remaining parts, and creating a targeted,
short and simple manual (ideally accompanied by some video clips) so that
support can be kept to a minimum (or at worst done over the phone).

The emphasis on eliminating moving parts and sources of error of course also
harks back to you "DHIS appliance" idea, Bob. One could even think of
running DHIS Live with H2 off USB sticks (though they are flimsy), which
could even be made to boot up something like DamnedSmallLinux.

 We have tried not quite yet succeeded in getting DHIS2 installed with 
 Tomcat/Postgres on Windows with a one-click installer, this my caveat 
 about a "supervised" install. There are a lot of things which can happen 
 on users machines and maintenance becomes a huge issue. DHIS is still 
 under intense development, and a lot of things change quickly. Upgrading a 
 single server is a piece of cake. Upgrading dozens or hundreds of off-line 
 machines is a true nightmare and a serious risk and resource drain to any 
 deployment. 
 
 I agree with Ola. Totally exclude an on-line server as an option first. If 
 you have already done that, all I can say is, be prepared for a LOT of 
 tech support.

Re: [Dhis2-users] [Dhis2-devs] DHIS 2 Live

[Jason Pickering]

The main benefit of an installer for us was

1) A pre-packaged database (straight DXF transmission will not carry
everything you need for a complete reserialization from a master database)
2) Proper shortcut links to make DHIS2 "look" like a piece of software users
are used to dealing with
3) Installation of Java when required (important!)
4) As Bob hints at, it may be required in the "draconian" situation to ship
DHIS2 with fewer features, although I am sure these could be relatively
easily circumvented by savvy users! We have tinkered with an extremely
stripped down version of DHIS2 in Nigeria which only does data entry, data
export, and nothing else built through a custom pom specifically for another
use case, but the issue is well worth considering.

Several versions of the installer are present in the DHIS2 /installers
directory of the main source tree. You can probably trawl through the
archives of the list as well for more info/debates on the utility of a
native installer. Let me know if you need some help to get things running if
you are interested in pursuing the installer route.

Best regards,
Jason

Simple answer is no one has tried it yet in such a production setting.
 And as Ola points out, you really want to avoid offline as much as
possible as it creates an exponential maintenance headache - both in
terms of keeping hardware and software running, but also keeping
metadata in synch.

Where you must be offline because you are indeed seriously offline
then the less software you have to maintain the better.

BUT, metadata maintenance will still be a human/policy/HR problem
regardless of the underlying db stack and is likely to be your biggest
headache.  The most draconian approach would be to to provide
districts with metadata (or even a metadata populated starter db file)
and require that they don't alter anything other than add data.  We
don't currently have a way to enforce this metadata ownership concern
through the software and in fact it becomes less of a concern as
things become more centralized.

Slightly less draconian being that they can add metadata but not alter
or remove state provided metadata.  When this happens, then the
exports to state level will be troubled as many districts will be
expected to be using the same dataelements, categories, datasets etc.

I wonder about the merits of a stripping out the metadata maintenance
modules in a such a lite-lite install?  Not sure how crippling this
would be.  Metadata import being the only way to update metadata.
Maybe that's too draconian but it could work for ultra-offline data
entry.

We have also created an H2 installer, which is considerably easier than the
Postgres installer. This would allow you to install this on a users machine,
with the documentation and a pre-populated H2 database, which may be
something to consider. Let me know if this would fit your deployment plans,
and we can discuss more details.

I agree with Bob that it is worth trying going with H2, as it does simplify
things considerably. It also provides a possibility for db backup (and
transmission) through the copying (and sending) of the whole db file (though
a monthly zipped incremental DXF export should be smaller).

 Hello,
 we're looking at what do to with offline installations for the
 implementation here in Ghana. Are there any reasons *not* to use DHIS
 Live? Can H2 be used (importing the metadata into an empty database), or
 should postgres be set up as well?

 There are 170 districts here, and about half of them might have to be
 offline installs so an easy-to-use solutions would be good.

 Thanks,
 Olav

Thanks
It seems the barrier for going offline should be quite high... Will have to 
look more into exactly how bad the connections are in the worse areas, and also 
into the offline data entry in 2.4.

As for those districts that are in fact offline, is the live package with H2 
sufficient? Keeping postgres out of the picture would likely reduce the amount 
of support required quite a lot.

Re: [Dhis2-users] [Dhis2-devs] DHIS 2 Live

[Jason Pickering]

I agree with both Bob and Ola.

We have tried not quite yet succeeded in getting DHIS2 installed with
Tomcat/Postgres on Windows with a one-click installer, this my caveat about
a "supervised" install. There are a lot of things which can happen on users
machines and maintenance becomes a huge issue. DHIS is still under intense
development, and a lot of things change quickly. Upgrading a single server
is a piece of cake. Upgrading dozens or hundreds of off-line machines is a
true nightmare and a serious risk and resource drain to any deployment.

I agree with Ola. Totally exclude an on-line server as an option first. If
you have already done that, all I can say is, be prepared for a LOT of tech
support.

Regards,
Jason

Re: [Dhis2-users] [Dhis2-devs] DHIS 2 Live

[Ola Hodne Titlestad]

Olav,

How offline are these districts? Can they not get connected through mobile
usb modems/dongles? There is so much to gain from online deployment that I
would check out every alternative of connectivity before deciding to go
completely offline. The mobile Internet solution is working very well in
Kenya. With the offline data entry capabilities in the upcoming 2.4, the
districts do not have to be online during the data entry process, which is a
major advantage in areas with poor/unstable connectivity.

Further recommendations on deployment can be found in the implementation
guide here:
http://dhis2.org/doc/snapshot/en/implementer/html/ch04.html

And a presentation on the same topic in the zip file with implementation
guide slides here:

Subject: [Dhis2-users] Browser support in version 2.4

Hi,

the upcoming DHIS 2.4 release is utilizing the "HTML 5 feature" web
storage (offline storage) which means that the following browsers are
supported:

- Firefox 3.5 +
- Chrome 4 +
- Safari 4 +
- IE 8 and 9

This means that IE7 is not supported anymore - sorry for that but we
are hoping people start using more modern browsers to take advantage
of performance and usability improvements. IE 7 now has only 5 %
global usage:

http://gs.statcounter.com/#browser_version-ww-monthly-201007-201107


regards, Lars


PS. we are aiming for a beta release tomorrow Friday 19, as we feel we
need more testing for the re-written data entry module and the new GIS
features before doing a stable release.
