I'd install and setup openmeetings instance on virualbox machine, it's goes pretty well. But sometimes after reboot when i'm trying to enter site it's redirecting to openmeetings/install page and says me to configure database, admin account etc.one again. I am using virtualbox(and snapshots maybe it rolls back some parts of a disk somehow?), ubuntu server 16.04 lts. Any ideas?
H2 creates DB in the current folder,
maybe some sort of clean-up is performed on reboot?
It is not recommended to use H2 in production. I would use any other supported DB :)
