Hi,
I guess it is stored in builtin_Rules.pie as commentary in the file reference
to file as Max. There is division commentary line in builtin_Rules.pie which
divide rules into Horst and Max. See :
...
...
//==============================================================================
// This rule file contains both OWL-Horst rules and OWL-Max rules.
// The OWL-Horst rule set is a subset of the OWL-Max rules
// The rules above this point all belong to OWL-Horst AND OWL-Max
// The rules below this point only belong to OWL-Max
// The next line is the dividing point:
// OWL-Max supporting rules
//==============================================================================
...
...
I'm not expert in the field of how Owlim stores rules, but what can I really
say 9200 rules is too many rules for one repository. TRREE is java based rule
engine and during compilation it probably creates highly optimized java
structures which could take such big amount of memory and java garbage
collector can't trash them as they had to be used everytime new triples are
inserted into repository...but it is only my guess. We can only hope TRREE
(owlim's reasoner) can procede so many rules in acceptable amount of time
(thought it is extremely fast rule engine and with owlim database and sesame it
is probably the fastest solution on the market).
I can share my experience with real application + Lubm test.
My notebook config:
P8600 Core 2 Duo, 2,4Ghz
4GB RAM
Win 7 64bit
Tomcat 7
Lubm 50 test (50 universities - around 5M explicit triples) with
horst-optimized loaded on my 832sec with Horst ruleset, with OWL2 RL 3200sec
and it contains "only" less than 100 rules.
Complexity of rule evaluation rises dramaticly as number of new rules are added.
In real applicatoin loading +
inferencing of 4M explicit triples with only 4 rules which create total
number of 6.5M triples (2,5M implicit triples) takes on my notebook 802sec. Of
course complexity of rules is also very important, I just want to say that 9200
could be many.
Number of rules indicates you need it for some research, in this case ontotext
provides Owlim SE trial evaluation copy(limited to short amount of time) which
is more optimized in... everything including TRREE :). You just need to apply
and provide some details of your reaseach.

Subject: Re: [Owlim-discussion] Problem with OWLIM, Sesame, Tomcat
Thanks Marek,
I managed to create the OWLIM repository with a custom rule set.
I am curious about one thing though. The rule set I am using contains around
9200 rules. I appended those rules in the Builtin_rules.pie file (in order to
have OWL reasoning) so I now have a huge rule base. OWLIM successfully loaded
the rule base but the memory consumption is huge even with no OWL file loaded.
Tomcat consumes 940MB of memory (normally it is around 150MB). The memory
consumption rises fast when the rule base is compiled but does not drop after
compilation has finished. Is this normal behavior? I restarted Tomcat and when
I try to access the repository I created, the rules are compiled again which
again leads to huge memory consumption.
On more thing, in which .pie file that comes with OWLIM-lite 4.3 distribution
are OWL/Max rules stored?
Thanks,
Babis
