My experience was that I needed explicit SQL: DELETE FROM load_list; I didn't see anything else. I also didn't experience any acceleration from TTLP_MT vs TTLP even though I had multiple cores. I only had 2 cores, and so I don't know whether it reflects on the product. ________________________________________ From: Eng.Bassam [bas...@gm...] Sent: Monday, January 25, 2016 12:21 PM To: Hugh Williams; vir...@li... Subject: Re: [Virtuoso-users] uploade TTl big file? I have split my file to 4 files, and Now I'm trying bulk loader strategy, I see after create the loader, I can see the files handled select * from DB.DBA.load_list; the first time was an error in my files, how can I try again run loader and check status in DB.DBA.load_list (delete last result)?? thanks On Mon, Jan 25, 2016 at 2:20 PM, Hugh Williams <hwi...@op...<mailto:hwi...@op...>> wrote: Hi Bassam, You can call the TTLP_MT() function as you are doing for a single file, but generally we would recommend the use of the Virtuoso RDF Bulk loader as detailed at: http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtBulkRDFLoader Which enable you to better manage the bulk loading of RDF datasets. The Virtuoso LDMeter functions can also be used to monitor the progress of data loads ie load rates etc as detailed at: http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtTipsAndTricksGuideLDMeterUtility Generally you need to ensure you have tuned the Virtuoso server for RDF performance, as if you run out of Buffers (memory) and have to swapping to and from disk, this will kill load rates and performance generally as detailed at: http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning Best Regards Hugh Williams Professional Services OpenLink Software, Inc. // http://www.openlinksw.com/ Weblog -- http://www.openlinksw.com/blogs/ LinkedIn -- http://www.linkedin.com/company/openlink-software/ Twitter -- http://twitter.com/OpenLink Google+ -- http://plus.google.com/100570109519069333827/ Facebook -- http://www.facebook.com/OpenLinkSoftware Universal Data Access, Integration, and Management Technology Providers On 25 Jan 2016, at 10:45, Eng.Bassam <bas...@gm...<mailto:bas...@gm...>> wrote: Hello I have a big TTL file about (2GB), I try upload it in virtuoso via ISQL: DB.DBA.TTLP_MT (file_to_string_output ('C:/Program Files/OpenLink Software/Virtuoso 7.2/vad/geneDiseaseAssociation.ttl'), '', 'http://localhost:8890/ontologies/DisGen'); is this right, or wrong? I need fastest way, and wish to see a progress bar to know how remaining time note: while it executing, I made COUNT(*) via SPARQL to see if count of added triples to graph increase or not, I think after 1 hour not add any triple on graph and ISQL still busy!!!! :( -- ----------------------------------- > Eng.Bassam Najeeb. >Software Engineer. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
