Hello all, It has been a while since I last ran multiple DHIS2 instances (each with its own database) on the same Windows server. Not sure if we have reached a consensus as to best practice on this (I actually think the best practice would be to run a Ubuntu server, but in many cases people find a change of OS an additional burden when there is so much knowledge to absorb about DHIS2 itself) I see the following options: 1. Multiple war files in the same Tomcat or multiple Tomcats on different ports. If so, just download the Tomcat zip file, not installer, and configure for different ports. 2. Each dhis.war needs a separate hibernate.properties. Is this best done inside the (exploded) war file, or is it best to create multiple environment variables? How to set the JAVA\_OPTS? The server has only 3GB RAM… If this has already been documented, I would be grateful for just a pointer. Thanks, Knut ---

In Nigeria, we have two completely separate instance of Tomcat with two environment variables DHIS2\_HOME=“/var/lib/tomcat6/conf/dhis2\_conf” DHIS2\_HOME\_NG=“/var/lib/tomcat6/conf/dhis2\_conf\_ng” The reason for the separate instances was really just to be able to allocate more CPU resources to a single Tomcat instance. You them modify /WEB-INF/lib/dhis-support-external-2.1-SNAPSHOT.jar Open up “mc” (or some other tool which can manipulate inside of a jar file) and navigate within the JAR file to META-INF/dhis/beans.xml and modify DHIS2\_HOME to DHIS2\_HOME\_NG and then exit mc. This instance will read from the DHIS2\_HOME\_NG environment. On Windows, two separate DHIS2 Live directories configured for different ports would seem to be a better solution. Then you do not need to worry about this hack.

Then you do not need to worry about this hack. Agree, using multiple live instances (with postgres) is probably the easiest setup. Again you would like to be able to start these automatically on reboot, but that should be possible.

That's right. dhis live doesn't use the environment variable - adopting instead the approach of "wherever I lay my hat, that's my home" 🙂 But it does this by using (and automatically configuring) a system property which takes precedence over the environment variable. That system property is called dhis2.home. You should be able to set this in a variety of ways in your automatic startup scripts eg. by adding "-Ddhis2.home=c:/mydhis" to CATALINA\_OPTS in tomcat startup script. It's an alternative approach which might suit you.

Thanks guys, running multiple instances of DHIS2 Live is definitely the easiest to set up and teach. In fact, I think there may be quite few instances where Tomcat is needed on Windows. And I don’t even think I need to worry about dhis2.home - since everything is confined to the folder where dhis2-live.exe resides. As Ola pointed out, the remaining and important issue is the automated startup after a power cut. Found some info here, grateful for further ideas.

Thanks for these answers. Please, is there a way one can put the hibernate.properties in the war file itself? This used to workout in 2.0 by just putting into WEB-INF/classes but now it just doesn’t work I’m in a PaaS offering where I don’t get access to the OS but just tomcat deploy.

So, I'm unable to set the env variables. Probably the best place to implement something would be as a context parameter ([Apache Tomcat Configuration Reference (6.0.53) - The Context Container](http://tomcat.apache.org/tomcat-6.0-doc/config/context.html#Context_Parameters%5C)). We could then fairly simply add yet another prioritized source of DHIS\_HOME: (i) check for context parameter called DHIS2\_HOME; failing which (ii) check for system property called dhis2.home; failing which (III) check for env variable DHIS2\_HOME. (the final fallback on linux is to use /opt/dhis2) The context should be configurable by the Paas provider. Any thoughts? Should be a quick blueprint + some few lines of code + testing.

So now I’m running three instances of DHIS2 Live on different ports and can stop and start each one individually. My new problem now is how to distinguish between them: 1. Most importantly, I would like to see a different hover text for each DHIS Live icon (I now have three identical ones) 2. Secondly, it would be nice if one could easily modify the text in the browser tab (i.e. the HTML element), which currently says just DHIS 2 for all of them. Would this be easy to do?

3 GB RAM sounds very little for serving three tomcat instances + a postgres server. I would recommend at least 8 GB here, as I assume this is a startup process with not that many users. As you get more online users and also more data to process, you will have to increase this. Especially it seems jasper reports (standard reports) get out of memory errors (PermGen space) with less (not sure exactly how much less) than around 1 GB: -XX:MaxPermSize=1024m" You could e.g. use something like this for each of the three tomcats/java processes: JAVA\_OPTS=“-Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=1024m” For an active DHIS 2 instance with many users I would allocate more, e.g. the Kenya online system uses: -Xmx6000m -XX:MaxPermSize=1000m This chapter in the implementation guide discusses server setup including memory settings for postgres and tomcat: [http://dhis2.org/doc/snapshot/en/implementer/html/ch08.html#d5e415](http://dhis2.org/doc/snapshot/en/implementer/html/ch08.html#d5e415) Ola > **···** > > On 18 August 2011 11:18, Knut Staring [knutst@gmail.com](mailto:knutst@gmail.com) wrote: > > > Hello all, > > > It has been a while since I last ran multiple DHIS2 instances (each with its own database) on the same Windows server.

In fact, there seems to be another server available, and one of the three instances is relatively temporary (it holds 6M rows from the old HMIS systems, parts of which we will import into the new dashboard system. So I guess what I have set up now is a relatively short term solution (though we all know those tend to linger for months and years…). I do agree with the need to change to a 64 bit operating system and slap more memory on the server. A few further questions: 1. As I mentioned, I am not using Tomcat at all, but running three DHIS Live instance, in other words Jetty. I assume things are a bit different then? 2. Are you recommending three JREs?

dhis-live is not really designed to be run as a service and I wouldn't really recommend trying. Given that it has a user interaction element in the toolbar etc. Running as a service is sort of the opposite of its defining use case which is to have a minimally configured clickable app to run on a desktop. I think there are lots of tips on the web regarding running tomcat as a service. Also HISP India has some previous experience in running many tomcat's on a single windows server for different states. Maybe Bharath or John might chip in how they have set up the service. Assuming that is, that they ran tomcat as a windows service. Possibly they logged in and manually started and stopped them. I always find it interesting when looking at the merits of windows vs linux servers that the argument is usually given that windows is more familiar and the hurdle to move to linux is too great. But when one scrapes the surface it seems that windows server skills are actually very scarce. People think they understand windows server because it looks just like windows. But you'll actually find much more knowledgeable support in our community for setting up a dhis+tomcat+postgres+ubuntu. Just my two cents 🙂 Re displaying different text on hover, its not a bad idea, but not one that anyone is likely to prioritize immediately. Maybe create a blueprint so the idea is not lost. From a zero-configuration perspective there is not much to go on mind you. We have the options of server port, database name or dhis home directory to distinguish between them, but using something mangled from those would at least provide something. A more nicely named instance would require an additional config parameter or a small dialog on startup.

Thanks for all the input - it has been very useful. I have come to realize that this current setup should be considered temporary (until the end of the year) and thinking&resources should probably now rather be dedicated towards setting up two national production machines by the end of the year (one for the national repository/dashboard, one for the HMIS), and these should align as much as feasible with the description in the link Ola sent: [http://dhis2.org/doc/snapshot/en/implementer/html/ch08.html#d5e415](http://dhis2.org/doc/snapshot/en/implementer/html/ch08.html#d5e415) In fact, we already also have a Linode, so far with only 4 GB, but that can of course be increased as needed.

I am disoriented with this. So I have tried to set dhis2.home on web.xml and the second war continues to use the DHIS2\_HOME. Setting tomcat to listen different ports means to waist machine resources that I do not have and the second instance will be used for tests. What is the recommendation now?

In Bob’s response above, he suggested an alternative approach which might work: “You should be able to set this in a variety of ways in your automatic startup scripts eg. by adding “-Ddhis2.home=c:/mydhis” to CATALINA\_OPTS in tomcat startup script.” [Next page](https://community.dhis2.org/t/multiple-dhis2-instances-on-windows/12389.md?page=2)
