[Virtuoso-users] Exception Violating unique index RDF_QUAD_POGS
Dear all, I've started testing version 6.1.4 but I've having the same problems with transactions when doing a bulk update. Concretely I get the following exception: com.hp.hpl.jena.shared.JenaException: Couldn't create transaction:com.hp.hpl.jena.shared.JenaException: rethrew: java.sql.BatchUpdateException: SR175: Uniqueness violation : Violating unique index RDF_QUAD_POGS on table DB.DBA.RDF_QUAD. Transaction killed. This is the code I use for the upload: VirtGraph graph = new VirtGraph (DATA_URI, DB_URL, DB_USER, DB_PASSWD); ... graph.getTransactionHandler().begin(); graph.getBulkUpdateHandler().add(jenaModel.getModel().getGraph()); graph.getTransactionHandler().commit(); ... It seems to work well at the beginning but as I'm trying to load a quite big dataset (I'm regenerating the Semantic XBRL dataset) at some point it starts throwing this exception for most of the attempts to load an RDF model.

No, I don't have transactions turned off. Should I do so and remove the begin() and commit() calls from my code then? Roberto García http://rhizomik.net/~roberto 2011/11/11 Hugh Williams hwilli...@openlinksw.com: Hi Roberto, Do you have transactions turned of when performing this bulk load operation, using the Virtuoso “log_enable” function as SPARUL operations are no transactional as detailed at: http://docs.openlinksw.com/virtuoso/rdfperformancetuning.html#rdfperfsparul http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtTipsAndTricksGuideDeleteLargeGraphs http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtTipsAndTricksGuideTransactionLogControl Hence the transaction errors you are encountering ...

Hi Roberto, Yes, you can remove these as there is nothing to commit ...
