I am using JBC 3 with local cache and jdbd cache loader, passivation false. I want create
a region where I just want to cache data in the memory only, so when evicted the object
should not go to the database and another region whose objects should go to database when
evicted. I created the following config but when the object gets evcited from the first
region (/root/cache/memory in config) JBC is trying to insert the object to database. How
can I restrict it.
