Hi Alex,
You only need to specify the Virtuoso SQL port number and not
host:port as you had done as the host is assume/must be localhost
anyway. If you check the dbpedia.log file then you will most probably
find this was the reason for the failure of the server to start ...

Hi Hugh,
Thanks for the link to that script. It seems like it should save me
a lot of hassle. However, at the moment, I’m running into another
small problem. I’ve followed all the instructions given in the
README.txt to the word, and executed the following command to
initialise the installation:
sh ./dbpedia_install.sh localhost:1111 alex *** alex...@gmail.com
Note that I’m running this from cygwin on Vista (32-bit) – I don’t
think that should create too much of a problem though.
The command fails almost instantly, printing the following to the
log file:
===============================
Install started
Sat Sep 5 16:50:49 GMTDT 2009
===============================
Checking for VOS setup
Starting Virtuoso server, please wait ...
Cannot start Virtuoso server, please consult dbpedia.log file
Started.
This script must be started in server working directory
The dbpedia dir containing all the files exists under C:\virtuoso-
opensource, and is the current directory at the point when I run the
installation script.
Do I have the dbpedia dir located under the wrong path? Is my
command-line option wrong perhaps?
Regards,
Alex

Hi Alex,
If a local DBpedia instance is what you are trying to setup we have
the following installation script used for loading up the DBpedia
3.2 datasets:
http://s3.amazonaws.com/dbpedia-data/dbpedia_load.tar.gz
The loading of the DBpedia datasets can take many hours depending on
the speed of the machine, as you have seen yourself with the ttlp_*
functions which our installer script uses.
We also provide a DBpedia Virtuoso Amazon EC2 AMI to enable users to
instantiate a running DBpedia instance in the cloud in less then an
hour, as detailed at:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtEC2AMIDBpediaInstall

Hi Hugh, Egon,
I've tried using the DB.DBA.TTLP_MT_LOCAL_FILE a large .n3 file (1GB
+),
and it seems to be working (or at least doing something), having
escaped
the \ in the path. However, it is taking an absurdly long time to
actually finish (I had to terminate the task), whereas uploading via
WebDAV to rdf_sink was very quick (< 30 seconds for a 1GB file).
Firstly, are the two methods equivalent? What I want to do is simply
make the RDF triple-store (for DBpedia) available via a SPARQL
endpoint.
There must be a recommended way for doing it - is this method it?
Thanks,
Alex
