Thanks Pavel. 1) i will look into this. 2) ok.
3) DefaultDataRegionConfiguration - What is default unit used for different properties to set size values ? Is it byte?? For - By default, only one region is configured with max size set to 20% of available RAM. What is the way to set max size ? MaxSize property? But documentation says it can be set maximum to 10 mb ?? How to set multiple regions?
