Hi Hugh,
I just realised that I was being silly and trying to run thte install
script from the default database, not realising that I needed to create
a separate database/service using dbpedia.ini. Sorry, still very much
getting used to using Virtuoso as a server! Anyway, thanks for pointing
me in the right direction..
Regards,
Alex

Hi Alex,
What is in the dpedia.log file as this will tell you why the server is
failing to start ? The dbpedia_install.sh script should be run from
the directory you extract the installer contents to, all you then need
do ensure your virtuoso server binary is in your PATH so it can be
located and the SQL and HTTP ports set in the dbpedia.ini file ( 1111
and 8889) are not already in use. Make sure their is not an lck file
(dbpedia_data.lck) file in place when the server is trying to start as
this will prevent it from starting also.

Hi Hugh,
Unfortunately that makes no difference. I still get the error "Cannot
start Virtuoso server, please consult dbpedia.log file". I've also
tried running from /c/virtuoso-opensource, with no luck - this gives
the message "The required file dbpedia.ini is missing" immediately
(not having even said "started").
Thanks for your assistance in this. Hopefully the issue should be a
bit clearer now, though I certainly don't see what's going on.

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
<mailto: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
