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. http://vlaurie.com/computers2/Articles/startup.htm Knut On Thu, Aug 18, 2011 at 12:12 PM, Bob Jolliffe <bobjolli...@gmail.com>wrote: > On 18 August 2011 10:29, Jason Pickering <jason.p.picker...@gmail.com> > wrote: > > 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.
