Dear Rob;


Thanks so much for your quick answer.

The easiest way to set up a TDB dataset is actually to start up Fuseki with a 
path to an empty directory and using the --update option to enable updates

I found some document to start up Fuseki with empoty dataset  from 
http://jena.apache.org/documentation/serving_data/index.html

========
Fuseki Server starting with an empty dataset

fuseki-server --update --mem /ds

  runs the server on port 3030 with an in-memory dataset. It can be accessed 
via the appropriate protocol at the following URLs:
  *SPARQL query: http://localhost:3030/ds/query
  *SPARQL update: http://localhost:3030/ds/update
  *SPARQL HTTP update: http://localhost:3030/ds/data
========

So I tried to run the server again using the above command.
=============

[root@ip-50-63-174-75 jena]# java -Xmx1200M -jar fuseki-server.jar --update 
--mem /ds
11:53:55 INFO  Server               :: Dataset: in-memory
11:53:56 INFO  Server               :: Dataset path = /ds
11:53:56 INFO  Server               :: Fuseki 0.2.5 2012-10-20T17:03:29+0100
11:53:56 INFO  Server               :: Started 2012/11/01 11:53:56 GMT-07:00 on 
port 3030
11:53:56 ERROR Server               :: SPARQLServer: Failed to start server: 
Address already in use
[root@ip-50-63-174-75 jena]# ^C

It has already exited by this point - control-C is going to the commandline.

===============

I got the error message saying " Failed to start server: Address already in 
use".
I tried shut it down using "control+c", but it seems not to work.

Do you have any idea of how to fix this problem?
Thanks so much for your answer.


There is another copy running already.  Find it and kill it.

Only one process can manage a port at a time.

TDB is a native RDF database not a flat file format so you cannot simply rename 
an existing RDF file to create a TDB dataset.

Please see the documentation for TDB
(http://jena.apache.org/documentation/tdb/) to learn how to create a TDB 
dataset.

The dataset location in your configuration file should be a path to directory 
where your TDB database has been created (or where it should be created).  The 
easiest way to set up a TDB dataset is actually to start up Fuseki with a path 
to an empty directory and using the --update option to enable updates.  Then go 
to the Control Panel in the Fuseki web interface and use the Upload File 
functionality to import the file into your dataset.  This will create a bunch 
of files in your directory, once created you can then take a copy of the 
directory (when Fuseki is not
running) in order to back it up or move it around as desired.

Hope this helps,

Rob

Dear Andy;



Thanks for your answers and pointing the mailing list archives as well.

What's "ghi.tdb"?


My dataset was stored in the flat file -->
http://data.ifpri.org/lod/ghi.rdf

I have read that Fuseki uses the TDB. So, I created a TDB (ghi.tdb)
file from the ghi.rdf file using the TopBraid Composer and put it into
under the "dataDir" directory.



I am using Jena to retrieve the data from ghi.rdf, but I am a kind of
new on the TDB.

What kind of files should I have to put under "dataDir" directory?

Is the .tdb file not the right format?

It's not clear what you are doing.  What operation did you perform?


Visit a URL?  Which?



That's a good question. What I would like to do is that I would like to
see the Fuseki main screen, using my dataset "ghi.tdb". That's why I
typed http://50.63.174.75:3030/.

What was the browser action?


What did you get?



I ran the Fuseki server again. The browser just keeps retrieving......
I didn't get any error message.

Did you copy the jar elsewhere  or are you running in the unpacked
installation directory.


I am running in the unpacked installation directory.



I am so sorry for asking many questions. However, this email list is
the only channel which I will get answers.



Thanks so much for your support in advance.



Best,

Soonho

Dear all;

I would like to ask some favor about Fuseki server installation.

I just tested an instance of Fuseki server -->

http://50.63.174.75:3030/ I created a data directory as subdirectory

"dataDir". I added "ghi.tdb" file into the directory.

Then, I ran the server

which asked you about the setup.

[root@ip-50-63-174-75 jena-fuseki-0.2.5]#  java -Xmx1200M -jar

fuseki-server.jar --loc=dataDir /ghi

14:15:24 INFO  Server               :: TDB dataset: directory=dataDir

GMT-07:00 on port 3030

Something was wrong since I didn't get the proper response from the
server.




What was the browser action?

What did you get?



http://...:3030/ is a simple plain HTML page from the pages/ directory.



Did you copy the jar elsewhere  or are you running in the unpacked
installation directory.



If you copy the jar, and you want the web pages, you need to



Or use --pages on the command line to name another directory.

Is there any log file to check what was wrong?




that is the fuseki log file (using log4j you can send it to a file)

If you find something is wrong, please let me know... It would be a
great help to a newbie like me.

Best,

Soonho
