Hi David/Michael,
After playing around with the settings, I believe our settings for memory
mapped files was incorrectly setup, it was set up to take too much memory,
due to this the GC would always try to clean up more memory than required.
After bringing down the mapped memory settings to a rec

I have a graph db with about 1 docs (:jurt) and about 12000 terms

To find out which documents are similar to a given document, based on a
count of common terms, I use this query

Use Neo4j Server and use the transactional cypher endpoint for most purposes
for special purpose graph operations or a custom domain protocol use unmanaged
extensions

Hi again,
Thanks Micheal for your answer.
I want multiple applications (e.g., web servers) connect to my database to
process requests. These applications are different processes running on
different PCs.
They must access data from the same graph database.
Is there any way to support this?
On
Any chance to share your db with us privately if you want to?
Will try to find some time to look into it.
Cheers,
Michael

1. According to Michael Hunger at neo4j, yes. I've also seen evidence of
this when optimising my own queries on his advice.
2. You are correct here, sorry. Will teach me to reply before coffee in the
morning.
3. Not sure, someone with better knowledge of the inner workings of the db
would have to
Thanks a lot for providing some inputs. However, for me, with the initial
posting of records i.e. 3814 relations for primary and some of the
secondary have 40K+ relationships, it is still not performing well - infact
doesn't return.
Few questions:
1. Are you sure that with one kind of relation
Hi Mohan
I'm entirely self-taught computing-wise and knew nothing about graph theory
before starting to play with Neo4j almost three years ago. So don't worry
too much, you'll pick it up :-)
There are some excellent videos/slides by Jim Webber and Ian Robinson
floating around the Intertubes that
Hi,
I have tried some Neo4J samples from the perspective of Java and
simple graphs. But I don't have a CS background. How much of graph theory
does one needs to know before using Neo4J for serious development ? One
answer could be that a relational model didn't require math knowledge.
Wh
OK, now I see my NeoStore wasn't closed really during the incident (should
have compared myself to other shutdowns I have, which really look like your
log snippet).
My Neo4j was installed as an init script and the incident happened during
OS reboot, no clue why the system decided to kill Neo4
You would check graph.db/messages.log for a clean shutdown sequence.
Something like this:

2014-01-20 18:30:21.714+ INFO [org.neo4j]: Database is no longer ready
2014-01-20 18:30:21.714+ INFO [org.neo4j]: GC Monitor stopped
Yes, I have the index entries but I don't have index values attached as
properties (but the index values are formed/merged solely out of the node
properties).
Could share the db, no sensitive information there, but I think we have
just reached the point when it's gonna be easier/cleaner if I
Hi!
Maybe you should check geoserver logs... you can find them in geoserver
data directory inside "logs" folder. Usually it's named geoserver.log.
There is also access to the logs via geoserver interface when logged with
admin account.

Hi Ankur,
I don't know if you already saw this, but here is neo4j at github:
https://github.com/neo4j/neo4j
Maybe there you can find what you are looking for. Also, there is a
dedicated topic to RDF and Linked Data (although linked data it is not
exactly semantic... but it's a starting point to w
I am trying to connect neo4j with geoserver with following steps:-
1.
Firstly I had taken clone for neo4j spatial project available on git
hub. Ref Link:- https://github.com/neo4j/spatial
2.
Then I run the command mvn clean install according to written blog
mvn
Sounds like a version issue. Can you check you use the same version ?
Cheers,
Michael

I have modified all the configuration settings.. My config files are now
getting loaded properly.. But now it is showing me the following error,
java.lang.NoSuchFieldError: remote_shell_enabled
at org.neo4j.server.database.Database.createDatabase(Database.java:77)
at org.neo4j.server.database.Data
I'm very busy at the moment, but, I hope have more time to contribute to
neo4j/SDN later :-)
