I am trying to use the "Jim Webber’s Doctor Who Data Set" from http://neo4j.com/developer/example-data/ in my Mac OSX with Neo4j 3.0.1-community.
I am following these steps (doc is here):
download the zip data file into the import directory (for convenience), and rename it as graph.db.
set dbms.allow_format_migration=true in $NEO4J_HOME/conf/neo4j.conf
Import data using $NEO4J_HOME/bin/neo4j-admin import --mode=database --database=graph.db --from=$NEO4J_HOME/import/graph.db/
start neo4j server
The neo4j console doesn't start, with this error message:
bin/neo4j console

Does anyeone know how to fix it? Has anyone managed to use the datasets in the doc?
Thank you!
Neo4j 3.0 allows direct upgrades from any cleanly shutdown Neo4j 2.x dataset. However the DrWho dataset you're referring to is from old days of Neo4j 1.9 (or even earlier). Due to this you need a two step upgrade process:
download Neo4j 2.3.3 (or any new 2.x release)
unpack the drwho.zip into data/graph.db
set allow_store_upgrade=true in conf/neo4j.properties
start the database and stop it gracefully
unpack neo4j 3.0.x
copy the data/graph.db from Neo4j 2.x to data/databases/graph.db
set dbms.allow_format_migration=true in conf/neo4j.conf
start up Neo4j 3.0.x

I am working through Neo4j section of Seven Databases in Seven Weeks book. I am at the Big Data section of day 2. I was able to download and move the Movie Database dataset example (cineasts_12k_movies_50k_actors.db) to data/databases. I then comment out dbms.active_database=graph.db and added the line
dbms.active_database=movies.db
in neo4j.conf file in /conf folder.
According to the instruction in the book, I ought to go into same file (neo4j.conf) to uncomment the line:
#dbms.allow_format_migrations=true
but such line did not exist in the file. And adding it to the config file threw up below error:

From online research, it seemed it (#dbms.allow_format_migrations=true) was a depreciated config option. I then went to the A.1. Configuration settings at https://neo4j.com/docs/operations-manual/current/reference/configuration-settings/ and from what I could make out there it seemed (my own conclusion) I could just uncomment dbms.allow_upgrade in place of dbms.allow_format_migrations (which was not available/ now depreciated) but I get below error:

Please advise on way around this so I can work with the example dataset (and then carry forward to practice with other example datasets).
Thanks a loaded bunch for your time.
NOTE: I run a windows 7 OS machine; my version of neo4j is the trial neo4j-enterprise-3.4.6; I use cygwin terminal alongside cmd prompt to follow along with the book; I am a beginner programmer (I don't know much). Also, this Error while running Neo4j: Not possible to upgrade a store with version 'v0.A.9' to current store version `v0.A.8` (Neo4j 3.3.1) seemed similar but was not helpful (no answers there).
I think this issue was caused by version compatibility of neo4j.
See https://neo4j.com/developer/kb/store-format-versions/ .
And there are two solutions for this issue. One solution is downgrading the version of neo4j you used to 2.1.0. Another is upgrading your data manually to 0.A.8.
Good luck!
I am currently unable to start a neo4j instance on a server where it was previously working. Neo4j produces an error saying one of the files is externally locked. From reading answers to similar questions I know this usually means another instance is currently using the store.
I have used lsof to look for any open files with 'neo' in their name but there are no open files.
I have used ps to look for any process with 'neo' or 'java' it it's name but no luck with that either.
I am not sure where to go from here to get neo4j working again. How do I figure out why this file is locked?

today I´ve updated my Neo4j Server (running on Ubuntu) from version 3.1.0 to 3.1.3! Everything works so far, so good.
After restarting my server, it crashes instantly. This happens everytime when I start/restart the server...
This is the part from the error log neo4.log

Does anyone had this problem after updating Neo4j or can help me with "understanding" that error log?
Thanks in advance ;)
UPDATE
When I start Neo4j I´ll get this message:
Starting Neo4j.
Started neo4j (pid 28724). By default, it is available at http://localhost:7474/
/usr/share/neo4j/bin/neo4j: line 176: /usr/share/neo4j/logs /var/log/neo4j/neo4j.log: No such file or directory
There may be a short delay until the server is ready.
See /usr/share/neo4j/logs /var/log/neo4j/neo4j.log for current status.
I´ve highlighted the 'suspect' part, which doesn´t appear before updating...
This is the ultimate cause in your call stack:
Caused by: org.neo4j.kernel.api.exceptions.ProcedureException: Unable to register procedure, because the name `apoc.algo.betweenness` is already in use.
This type of exception, where an APOC procedure name is already in use, can be seen when you install a new APOC plugin .jar without removing an existing APOC .jar.
If this applies to you, delete the old APOC .jar and try starting neo4j again.
I have been using Neo4j for more than 3 months on this server. Not sure what changed, but today morning I am unable to start Neo4j server.
Till today everything was fine and there were not changes that I know of were made to Neo4j or anything else.
I am currently using neo4j 3.1.0.
The following is the error log.
xxx#dataserver:~$ sudo neo4j console

Stop service
Change dbms.allow_upgrade to true in neo4j config file
Start service again
I had the same problem, and upgrading the db fixed it. I would also suggest changing the password if you are still using default password. Once you start the service it should upgrade the database, once upgraded, you can change the dbms.allow_upgrade to false again if you dont want neo4j to update automatically.

The server lib were magically updated to 2.3.0-M01.
How do I fix this problem? Would downgrade to the older binary help me? If so, which binary supports NodeStore v0.A.4?
Seems like you have upgraded your Neo4j instance but it will not start since the database store files have not been upgraded. These require an explicit upgrade. What was the version of Neo4j you were running previously?
To upgrade your graph database explicitly you need to set
allow_store_upgrade=true
in \conf\neo4j.properties. Note that this line should be present in the file already but commented out with a #.
Bear in mind that 2.3.0-M1 is a milestone release and may not be stable. The latest stable version is 2.2.1.
