Re: [Owlim-discussion] Problem with OWLIM, Sesame, Tomcat
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.

Re: [Owlim-discussion] Problem with OWLIM, Sesame, Tomcat
Hi Babis, I'm sorry to hear you are having trouble configuring OWLIM. All steps you made sound right and I'm not sure what could have caused the setup problem. One thing I could advise at first glimpse is to try and use the pre-built sesame workbench WARs we distribute together with OWLIM (see /sesame_owlim in the distribution). They have OWLIM built-in and you will only need to drop them in the webapps folder of the tomcat installation and restart the server. Let me know if using these WARs results in a similar exception being thrown.

Re: [Owlim-discussion] Problem with OWLIM, Sesame, Tomcat
Hi, if you don't need to do it through workbench I suggest far easier way to create custom ruleset. My solution is connected to windows... windows 7 64bit 1. Deploytwo official war-files included in owlim distribution .zip file (in folder /sesame_owlim ) by copying them into webapps directory in Tomcat (make sure you delete your previous attempt described in your mail) 2. Unpack console.zip (also in folder /sesame_owlim in zip file) 3. Run console through console.bat(or .sh depends on your OS) (.../openrdf-sesame-console/bin/console.bat) 4. Your first command in console should be : connect http://localhost:8080/openrdf-sesame. 5. Then try whether other repositories already exist by command : show r. a) it there exists repository with the same name you want to create run command : drop nameOfYourRepository. 6. Copy your .ttl file into C:/Users/YourAccountName/AppData/Roaming/Aduna/OpenRDF sesame console/templates/ (notice : folder /AppData is in windows normally hidden) 7. Open console and run command (dont forget to run step 4 - connect to localhost) create nameOfYourRepository. Notice : nameOfYourRepository should be equal to name of your .ttl file which you should copy into .../templates folder (see step 6) Notice : every command in console should end with dot (.) After these steps you will see your repository also in workbench but it will have your custom ruleset specified in your .ttl file and no error should occur. Workbench will normally interact with such repository, so dont worry about it :).

Hi Marek, Thanks for your suggestions. As the OWLIM community grows, it has become apparent that we need a better way to organise things and have been considering this kind of forum. I can't promising anything, but I feel it would be nice to have something like this organised later in the year. We are always pleased to hear about user experiences, so if you have performance analysis data for your use-case then this would be something useful. It gives us another target to aim for.

Re: [Owlim-discussion] Problem with owlim-lite-5.0.4915
Marek,
Thanks for the suggestion but, alas, I did not help. I’m now running Tomcat
7.0.26.
However, what I failed to understand the difference between the:
Imported RDF files(';' delimited and use '/')
and
New triples file (use '/')
fields in the Workbench’s New Repository form. It appears that you should use
the later for loading RDF files from your file system.
With this sorted-out it now appears to be working.
Regards
Philip

Hi,
I'm using the Owlim SE 5.0 on similar configuration. The only difference is Im
using Tomcat 7 and I don't have these problems with Owlim 5.0(finally), because
I've experienced this issue with previous versions of Owlim. Usually tomcat
restart or complete redeployment really helped (remove deployed folders
