Narayan Sujay, Thanks for your interest in MonetDB. Rather than directing technical questions to the CWI organization webmaster, you are supposed to post on one of the relevant mailing lists such as this one (monetdb-user@lists.sourceforge.net).

I can write simple queries in the client cmd window. I am trying to connect MonetDB with one of the SQL frontends like DB visualizer etc and I am not able to do this. Please help me out with instructions. I followed the instructions on the webpage but still getting errors connecting through db visualizer. I think it is the problem with the JDBC drivers. Please let me know excatly where to find the driver on the local computer after I have installed Monet DB. My Main goal here is to load large Data sets in MonetDB. Please tell me a way to do this for Monet DB. The error I get in DB Visualizer is: Long Message: Cannot connect to ORB Details: Type: javax.naming.CommunicationException Stack Trace: javax.naming.CommunicationException: Cannot connect to ORB [Root exception is org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No] at com.sun.jndi.cosnaming.CNCtx.setOrbAndRootContext(Unknown Source) at com.sun.jndi.cosnaming.CNCtx.initOrbAndRootContext(Unknown Source) at com.sun.jndi.cosnaming.CNCtx.<init>(Unknown Source) at com.sun.jndi.cosnaming.CNCtxFactory.getInitialContext(Unknown Source) at javax.naming.spi.NamingManager.getInitialContext(Unknown Source) at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source) at javax.naming.InitialContext.init(Unknown Source) at javax.naming.InitialContext.<init>(Unknown Source) at com.onseven.dbvis.db.A.G.Ą(Z:3155) at com.onseven.dbvis.db.A.G.Ĭ(Z:2675) at com.onseven.dbvis.db.A.E.Ĭ(Z:98) at com.onseven.dbvis.db.A.D.ā(Z:2056) at se.pureit.swing.A.O$2.run(Z:1192) at java.lang.Thread.run(Unknown Source) Caused by: org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No at com.sun.corba.se.impl.logging.ORBUtilSystemException.connectFailure(Unknown Source) at com.sun.corba.se.impl.logging.ORBUtilSystemException.connectFailure(Unknown Source) at com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl.<init>(Unknown Source) at com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl.<init>(Unknown Source) at com.sun.corba.se.impl.transport.SocketOrChannelContactInfoImpl.createConnection(Unknown Source) at com.sun.corba.se.impl.protocol.CorbaClientRequestDispatcherImpl.beginRequest(Unknown Source) at com.sun.corba.se.impl.protocol.CorbaClientDelegateImpl.request(Unknown Source) at com.sun.corba.se.impl.resolver.BootstrapResolverImpl.invoke(Unknown Source) at com.sun.corba.se.impl.resolver.BootstrapResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.resolver.CompositeResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.resolver.CompositeResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.resolver.CompositeResolverImpl.resolve(Unknown Source) at com.sun.corba.se.impl.orb.ORBImpl.resolve_initial_references(Unknown Source) ... 14 more Caused by: java.net.ConnectException: Connection refused: connect at sun.nio.ch.Net.connect(Native Method) at sun.nio.ch.SocketChannelImpl.connect(Unknown Source) at java.nio.channels.SocketChannel.open(Unknown Source) at com.sun.corba.se.impl.transport.DefaultSocketFactoryImpl.createSocket(Unknown Source) ... 25 more The results of this submission may be viewed at: http://www.cwi.nl/en/node/757/submission/3152
