Neo4j Enterprise VM Version 3.5 Database Transfer - neo4j

I upload Neo4j Enterprise VM Version 3.5 to my Azure account. So right now I am using Neo4j in the Azure. 
I created before my database in the local desktop edition and I want to transfer it to Remote one (Neo4j Enterprise VM Version 3.5)  which is in Azure . 
However I couldnt find a way to do it. There is no option in Neo4j Enterprise VM Version 3.5 to put my graph.db zip file.
Someone can help to how transfer my local database to remote one ?
Thanks

The documented way to transfer a neo4j DB is to use:
The neo4j-admin dump command on the originating machine to create a dump file.
The neo4j-admin load command on the destination machine to fill a fresh DB from that dump file.
Refer to the documentation for more details.

How to start the Community Edition in Neo4j Desktop?

I would like to use Neo4j to learn how graph databases work and make some experiences with my own datasets. According to that and since Neo4j claims to be open source I've downloaded the Windows Neo4j Desktop version, but every project and database initialized shows the "Enterprise" attribute which means that I just initialized the Enterprise edition.
Any idea how to setup a project and a database based on the community edition?
Solved it. If you dont setup path variables you have enter the bin directory via cmd and type "neo4j.bat install-service" and then neo4j.bat to start the database-server. The officiall installation instructions should have those details.
just open a commandline in the bin folder. There you execute the command "neo4j.bat console" which creates a local server, that you then reach via localhost:7474.
The neo4j Download Center allows you to choose between downloading the Enterprise Edition, the Community Edition, and the Desktop.

Copy Neo4j Desktop Edition DB to cloud

I am trying to get the Paradise Papers running on an AWS cloud server. I installed Neo4j Desktop on my mac, and commissioned a server by deploying the AMI from https://aws.amazon.com/marketplace/pp/B071P26C9D.
I then copied the data from the Desktop install to the cloud install, updated the neo4j.template file to point to the new directory, and restarted the service.
The problem is that I can no longer connect to the server. In the log files I can see the following lines (along with a lot of diagnostic information).
2018-09-30 07:41:59.920+0000 INFO [o.n.k.i.f.CommunityEditionModule] No locking implementation specified, defaulting to 'community'
2018-09-30 07:42:00.104+0000 INFO [o.n.k.AvailabilityGuard] Requirement makes database unavailable: Database available
I suspect that there may be some kind of licensing or version constraint that is preventing the database from running. Could this be possible? Or is it something else?
Your issue is not related with a licensing or version problem.
In your debug.log, I don't see any message that can explained your issue.
Is there something useful in the neo4j.log file ?
Can you try to start neo4j after after removing all your plugins (apoc) ?
Can you try to start Neo4j on an empty database ?

Neo4j community edition in read-only mode

I'm trying to make the config flag dbms.read_only=true working with Neo4j community edition (I know there are user roles in the enterprise, but I'm not wealthy enough for their expensive fees).
I've done this:
Created a database as read/write, using Neo4j Desktop (v1.1.8) under Mac and 3.4.5 as database engine.
Populated it with just a few nodes
Stopped, set dbms.read_only=true and restarted
At the last step, the server logs shows the error: "UnsupportedOperationException: Can't create index writer in read only mode" and shuts down. So, is that option really (still) working?
Neo4j Desktop is meant for usage with Enterprise Edition (you do get an individual license for usage for dev purposes only), not Community Edition.
I believe there's an issue with dbms.read_only=true and running via Neo4j Desktop, but there isn't any problem using the server deployment of Neo4j Community edition and using that setting.
My advice would be to download the community edition from Neo4j and use that directly rather than going through Neo4j Desktop.

Its lock file has been locked by another process - Neo4j Embedded

I am developing a embedded application of the Neo4j and I try run this but I get this error:
Store and its lock file has been locked by another process:
/home/dev/neo4j-community-2.3.2/data/graph.db/store_lock. Please
ensure no other process is using this database, and that the directory
is writable (required even for read-only access)
I know that is because the neo4j server application is running and it lock the directory to writable for another application.
But I want run both, the neo4j server with browser studio and my embedded application.
I am use the community edition 2.3.2 in Linux.
How can I do it?
It is possible in enterprise version?
Thanks
On the very same directory you can only run at most one instance at a given time.
Enterprise edition enables master-slave replication, so the graph.db is folder is propagated from master to slave instance. This would be an option for you.
I assume you want to access you embedded instance via the browser. See this blog post http://graphaware.com/neo4j/2014/11/21/neo4j-browser-with-embedded.html - be aware this one is based on 2.1 - as far as I remember in 2.3 some things have changed since then.

Migrate Neo4j data to GrapheneDB

So I’m ready to move my Neo4j database from my local machine to GrapheneDB for further development.
How can I move the data on my local machine to the GrapheneDB remote store?
I'm one of the founders at GrapheneDB.
Moving your data from your local machine to GrapheneDB is simple:
Stop your local instance: $ bin/neo4j stop
Put the contentes in a tarball or other type of compressed file (zip, gz): tar -cjf graph.tar.bz2 data/graph.db
Sign up or log in to GrapheneDB and create your database instance
Once the DB is created, navigate to the admin and use the restore feature to upload your compressed store files
Notes:
Neo4j should be stopped before copying your store files into a compressed file
You should restore into the same or a higher version on GrapheneDB, i.e. 2.0.X into 2.1.X or 2.1.6 into 2.1.6.
I hope this helps.
