I struggling to get the "Musicbrainz" data set running on my local machine (MacBook Air, Mountain Lion).
What I did? (Basically what the video said)
- Downloaded data set directly from http://www.neo4j.org/develop/example_data
- Downloaded fresh Neo4j-Community-2.1.5
- Extracted the data set, renamed it to graph.db and copied to /neo4j-community-2.1.5/data/graph.db
- Run the server:
./bin/neo4j console, but neo does not start - not even an exception is thrown!!!!
Gerardos-MacBook-Air:neo4j-community-2.1.5 Gery$ ./bin/neo4j console WARNING: Max 256 open files allowed, minimum of 40 000 recommended. See the Neo4j manual. Starting Neo4j Server console-mode...

I tried several settings in neo4j.properties, but nothing, see properties below ...
use_memory_mapped_buffers=true neostore.nodestore.db.mapped_memory=300M neostore.relationshipstore.db.mapped_memory=3G neostore.propertystore.db.mapped_memory=500M neostore.propertystore.db.strings.mapped_memory=500M neostore.propertystore.db.arrays.mapped_memory=0M neostore.propertystore.db.index.keys.mapped_memory=15M neostore.propertystore.db.index.mapped_memory=15M
allow_store_upgrade=true
I was hoping that this would work out of the box. What am I missing ...?
