Play Area -- Second OFBiz Instance

[Craig Parker]

I've got OFBiz up and running on my Linux laptop with a MySQL backend. 
Is it possible to have another instance running somehow at the same time 
that uses a different DB? Well, maybe three different DBs -- looks like 
I'm currently using ofbiz, ofbizolap, and ofbiztenant.

What I'm aiming for is to have a "live" and a "play" area eventually. If 
I want to go try something, I want to keep from breaking my install.

Initially though, I want to have the default data in one, and the other 
a blank slate.

Right now the install is sitting in /ofbiz and being started up with a 
bash script via systemctl. I've not tried it yet, but  I'm wondering if 
I have to create the three new DBs, and duplicate what I have in /ofbiz 
to something like /ofbiz-play, then create a similar startup script that 
fires up things in that /ofbiz-play directory.
