Re: [Neo4j] User Digest, Vol 45, Issue 35
Craig
First of all, I must apologise for my slow response - I have been on
extended leave (with, deliberately, no internet access - you can live
without it!).
I am in the process of writing-up (for internal record) the testing process
I have been using to benchmark RTree versus PostGIS. I will post a copy.
Clearly, from your response, there are a number of possible routes for
improvement but, at this stage, I want to be certain I have the optimum
tuning settings for Neo4j for the current RTree implementation. At present,
all settings are 'out of the box'. I have little experience of Neo4j (but a
lot database experince - relational, multi-dimensional, hierarchical) so
some basic reworking of the settings will be a great help before I scale-up
the test.
Thanks Dave

Davide
Sorry for slow response - been on extended leave.
I have already amended ShapeFileImporter to included maxNodeReferences (and
minNodeReferences - aka M,m) and found they made precious little difference
to the performance. As a result, I assumed that I needed to ensure I had the
optimal basic Neo4j settings and repeat my tests for different value of M
and m. I am currently writing-up my results so far and will post them in the
next days or so.
Thanks Dave

[Neo4j] Trouble with neo4j.py - Ubuntu 10.10
Has anyone else experienced difficulty running neo4j.py on Ubuntu 10.10?
I'm having difficulty building the package. I've installed Jython, but
am receiving the following traceback:

You will need to make sure that you either have JCC installed prior to
installing Neo4j.py, or that you have JPype installed alongside with
Neo4j.py. With setuptools these could have been automatically installed.

My CPython can find setuptools fine.. I wonder if it's just something I've
done incorrectly when I installed Jython.

Re: [Neo4j] Unfinished transaction - cannot open db
Hi Andi, as the database reruns all not synced transaction on startup after a startup and clear shutdown all transaction that should be accounted for should be applied and all others discarded. So an new EmbeddedGraphDatabase( path ).shutdown() should clean it up for you (or starting and stopping the server). Please don't delete any of the files otherwise you risk corrupting your database. Would you please provide the error message that you get from neoclipse? (And the StackTrace if possible). Hope that helps, if not, let us know.

Re: [Neo4j] Trouble with neo4j.py - Ubuntu 10.10
No, that is just a warning. The real problem seems to be that the setup
script is unable to find the artifactId in one of the dependency poms.
I have yet to come up with a good way to make the script retrieve the
dependency jars.

Re: [Neo4j] Unfinished transaction - cannot open db
Hi, I get the following messages, when I start from the command line. As I supposed the problem is due to the random stop of my program, when I debug. I mean when I debug, I just click the stop button in Eclipse. This seems to cause the problem. But how do I work around this? 12.01.2011 19:55:50 org.neo4j.kernel.impl.transaction.xaframework.XaLogicalLog doInternalRecovery INFO: Non clean shutdown detected on log [../nioneo_logical.log.1].

Re: [Neo4j] Unfinished transaction - cannot open db
Hi Andi, That just shows that the recovery of the transaction started. Does it also say that it finishes the recovery after a while? You should allow it to end the recovery and then do a clear shutdown of the database. If you connect to the db with neoclipse it shouldn't pose any problem. How big is the dataset that you've stored in the graph? Thanks Michael Am 12.01.2011 um 20:05 schrieb Andreas Bauer: > Hi, > > I get the following messages, when I start from the command line.

Re: [Neo4j] Unfinished transaction - cannot open db
Hi, I let neoclipse do its work. After the messages mentioned below, only checking service ... starting neo4j checking service ... starting neo4j checking service ... starting neo4j checking service ... appears, interrupted by the message "The neo service is not available"; and after I clicked "ok" "The database seem to be in use. Please make sure it is not in use or change to another dtabase location." is shown. The size of the db is quite small (at the moment), neostore.propertystore.db is 946kb and neostore.nodestore.db 45kb Cheers, Andi Am 12.01.2011 um 20:10 schrieb Michael Hunger: > Hi Andi, > > That just shows that the recovery of the transaction started.

Re: [Neo4j] Unfinished transaction - cannot open db
I rather meant your program. Just have it start up, and shutdown() the EmbeddedGraphDatabaseService cleanly. Afterwards try to use neoclipse.

Hi, I use the latest stable version for mac available on the neo4j homepage (V1.2). And no, I didn't delete anything.

[Neo4j] Newbie Question related to IMDB
I'm new to Neo4J and have successfully loaded the IMDB sample. Is there an easy way to migrate the IMDB sample from the built-in jetty server to either Tomcat or the Neo4J application server? I've looked through the list but haven't seen that answered anywhere. Looking forward to diving in and working with Neo4J. Thanks Dave Fauth ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
Re: [Neo4j] Newbie Question related to IMDB
Hi Dave, Do you mean that you want to deploy Neo4j onto Tomcat? At the moment that's not supported (we don't produce a .war out of our build). Not sure what you mean by Neo4j application server though - can you clarify? Jim On 13 Jan 2011, at 02:30, david fauth wrote: > I'm new to Neo4J and have successfully loaded the IMDB sample.

Re: [Neo4j] Newbie Question related to IMDB
HI Dave, the imdb app is packaged as a war using maven. So you can deploy that easily to Tomcat. The Neo4J Server provides a RESTful interface and is not intended to host applications. If you just want to use the imdb data as your dataset in the Neo4j Server then just copy the files from the original place (e.g. the imdb target directory) to the db/data directory of the server.
