[rules-users] Drools Fusion High Availability

[Wolfgang Laun]

HA as in High Availability, I suppose.

SW alone won't make it HA. Does your application warrant s.th. like 2oo3 or
similar? Running such a system with an application based on Drools will
require some middleware for messaging which is clearly out of scope for
Drools. Some support may be there for such features as recovery, if you need
4-9 or similar.
