I'm using Neo4j Desktop Version 1.4.3. I've created a new project named "Yelp Project", then uploaded the yelp dump file in it, but I'm not getting the option "Create new DBMS from dump". So I selected Add --> Local DBMS and created a database. But when I open Neo4j Browser, there are no nodes and relationships. I'm not able to figure out how to get this done, can someone help refer image
The feature that you are looking for is not yet available for Neo4j desktop Windows version. See below community thread discussion then scroll at the bottom.

I am trying to edit the settings of my AuraDB hosted neo4j instance, specifically, trying to set the following line:
apoc.import.file.enabled=true
I have looked at the official tutorial and many other places, and for the life of me, I am not able to find out where either the "settings" button is located, or how to locate the neo4j.conf or apoc.conf files. It seems that something has possibly changed in a newer version. I have tried both in the browser at https://console.neo4j.io/#databases and in Neo4J Desktop. For the desktop application, I am running it on Ubuntu via the .appimage. I created my database on the website and connected via remote connection following this guide.
Some things that might help me solve the issue:
Is it possible to open a shell in auradb to let me run normal bash commands?
Is the .conf accessible "within" the .appimage?
From the official description of File locations, I am supposedly able to do the following in Neo4j Desktop to find the configuration file:
From the Open dropdown menu of your Neo4j instance, select Terminal,
and navigate to /conf/neo4j.conf.
Yet, when I press the Open dropdown menu, I do not see a Terminal option. What I get is Neo4j Browser, Neo4j Bloom, and Neo4j ETL Tool.
Aura is a managed database - which is to say that you don't get low-level access to configuration of the kind you're describing. The documentation you're looking at relates to self-hosted instances of Neo4j, where you're the one managing and configuring the instance from scratch and where you have that level of access to the underlying configuration.
To the problem you're trying to solve, the following article entitled Loading data into Neo4j Aura is your best bet for the currently available options for loading data into your managed database.
Per the documentation, APOC is installed in Aura databases, but only a limited set of functions and procedures are enabled (as of May 2022). In particular, only a small subset of apoc.import procedures are available - from what I can see, CSV and GraphML support is enabled via apoc.load.csv and apoc.load.graphml, while you also have access to apoc.load.json and apoc.load.xml.
Lists of the currently supported procedures and functions are available at the foot of that document:
Neo4j Aura Supported APOC procedures (updated).json
Neo4j Aura Supported APOC functions (updated).json
From a Neo4j Aura Knowledge Article:
In Aura, we currently do not support changing any property that may
exist in the Neo4j product and defined in neo4j.conf.
this might be a stupid question but I'm new to neo4j.
I'm using the desktop version and from there I created a new database from a new project. I also can see it from the browser and I can see data and stuff.
But if I go on my terminal and run
cypher-shell
and from there I type
SHOW DATABASES;
I can only see the default dbs:
Does anyone know what I am doing wrong?
From the Neo4j desktop, you'll see the Start/Stop and Open buttons for a project database. Just to the right of these are 3-dots. Click on that and then open folder. This will get you to the various folders for the database. It's useful for seeing the size of the database, working with the config file, managing transaction logs, etc.
My Neo4j version is community-4.2.4 in the Mac OS.
I used 'bin/neo4j-admin load --from=xxx/g.db.dump --database=xxx.db --force'. And succeed in finding db file in /data/databases as photo showed below.
enter image description here
But the result returned in Browser adding 'show databases' and cannot find the database what I want.
Thanks u guys all for helping me.
OR sending email for communicating more at masichengyo#gamil.com.
So neo4j-admin load and neo4j-admin restore take care of setting up the db in the filesystem. Back in the 3.5.x days this was enough, provided the name of the graph directory matched the name of the active graph configured in the neo4j.conf.
In Neo4j 4.x we support multidatabase, and the system database is where we can do things such as creating new databases, and if you CREATE DATABASE in the system db with the name of the new database, it will use just use the files it finds and create the entry in the system db, allowing you to use it and switch to it in Neo4j.
Since you're on community edition, you won't be able to create a new database, you're restricted to only the neo4j database, so your import would have to force it using neo4j as the db name, and it would overwrite your current neo4j db.
If you need to create multiple databases besides neo4j and system, then you need to be using enterprise edition.
I am really sorry to ask a simple question like this, but it is getting frustrating. I installed neo4j 4.0.4 on my Windows machine, created a new project as shown in the official tutorial video and set a password for my local graph. Funnily, the tutorial video ends after setting the password and opening the browser not showing how to perform Cypher queries on this newly created database. In neo4j Desktop my database is shown correctly and it seems to be up and running.
However, when I try to connect to this database via the browser, I do not see the database at all. It is so confusing when connecting to the server to specify a username and password, if you only need to set a password for your database?! The default neo4j user can see the system and default database but not my project database. In addition, I cannot link files from the project directory in Cypher queries. I tried to disable authentication, but it did not help at all.
When I issue SHOW DATABASES command, it does not list my database as well.
Update / Edit:
Seems I misunderstood the concept of projects. Every database is named neo4j - default, regardless of the name specified in the project ?!. However, I still cannot access project files. So far, I copied the files manually in the database directory under "imports". But I guess that is not the intended way.
After importing data to this default database, it still shows no data in the project itself.
Data files in the imports directory are not automatically imported into the DB. That is because neo4j has no idea how you want to store that data as nodes and relationships.
So, it is up to you to determine your desired data model, and then write the appropriate code to enforce that data model.
You can take a look at this page to learn about how to import CSV data (probably the most commonly used import data format).
I recently upgraded to Neo4j 4.0.6. (Community Edition)
After upgrading my "old" Neo4j database the browser :sysinfo command (Chrome and Safari) doesn't show any information. It just displays the empty tables for Store Size, id Allocation etc.
All the tables and labels are shown as in Neo4j 3.x but no values are prompted. It doesn't matter if I change the "Use Database" settings (switch to system and back) or if stop and restart the server. No entries for :sysinfo show up.
Any idea how to reactivate the DB :sysinfo in the browser interface again is greatly appreciated.

I tend to think its an issue with recent versions.
It caused me to believe a multi upgrade store was incorrect.
So I went the long 'dump to cypher and reimport' route.
After node import, sysinfo was working (4.1 CE)
This behaviour appeared when I added relations
CALL db.schema.visualization() is broken too (no graph tab)
What a time loss, I tell you.
Wont count the days
Somewhere I read to reset the indexes, be sure btree was used.
No, it didnt work.
your next move is to file an issue
It seems ppl also have this issue since 3.5 w/ clusters
