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.

Thanks

Ime

Subject: Re: [Dhis2-devs] Multiple DHIS2 instances on Windows


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.
