RE: [rules-users] Need Help on using rules in Multiple Threads

I assume (from "...each thread will execute the rules...") your threads have their own workingmemory and once you've loaded the 500 records you call fireAllRules()? If this is the case then the activations should be correct for the subset of records asserted but this could differ to the results you expected; for example:- Rule 1 when ObjectA() ObjectB() Then System.out.println("Rule 1 activated"); end All records Record 1: ObjectA() Record 2: ObjectA() Record 3: ObjectB() Record 4: ObjectB() Subset 1 (records 1 - 2) Record 1: ObjectA() Record 2: ObjectA() Subset 2 (records 3 - 4) Record 3: ObjectB() Record 4: ObjectB() If you have two threads asserting each subset to their own WM and firing all rules; "Rule 1" will never be activated. If you have two threads asserting each subset to a shared WM and fire all rules; "Rule 1" will be activated.

Each thread will execute the rules but I am not getting the expected result. May be the threads object are conflicting due to multiple thread execution.
