Hi Aby, I don't know if there is other limit than the physical memory size, but if it exists is far greater than 6000+. I think your problem is that you have duplicate records in your DB, and all the facts in the engine are unique. When asserting a new fact that is identical to a previously asserted one only one remains.

So I fired (facts) immediately after asserting 10000 facsts. I could see only 6000+ records. But I am sure the JAVA function asserts 10000 records. > > Why is it so? Is there a limitation for number of facts in JESS?(very unlikely) Or is this is a limitation of the evaluation copy? I downloaded the evaluation copy from Manning website after I purchased the JIA eBook. Or am I doing something wrong? > > thanks > > > Yahoo!
