I installed a windows service using InstallShields generated msi file.
How am I able to get the version of the service using WMI-Query? I already checked win32_Service but there's no version number displayed. Is this information queryable using WMI or do I have to use the registry for this scenario?
Okay, got it. The information is stored in Win32_Product.

I cannot get APOC to work on neo4j.
Documentation is good ... when present!
I installed the apoc library via Neo4j Desktop:
Launch Neo4j Desktop
Locate DBMS
Select Plugins tab on right
installed the plugin
Then I open a project.
I try:
CALL apoc.load.json("file:///person.json")
YIELD value
RETURN value;
but
There is no procedure with the name `apoc.load.json` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.
Indeed The available procedures does not display apoc, in spite it is installed.
Then, after I cleared out that Neo4j Desktop is not using the installed community edition I had, and found that i can find the installed versions under the "more" options > Terminal:
I checked that my neoj4.conf file have these lines:
# Leaving this unconfigured will load all procedures found.
#dbms.security.procedures.allowlist=apoc.coll.*,apoc.load.*,gds.*
(commented out, to load everything, so apoc should load...)
I think I have done OK, as here:
APOC installation neo4j desktop
I also tried to delete the project and set it up again:

but still not working...

How do I get APOC to work ??
Do I have to install it for each project ?
Do I need to configure it for each DB in the project ?
I am using neo4j desktop 1.5.6.
#Edited
today I replicated steps of yesterday, paying attention to the recommendations of #William Lion answer.
At launch of neo4j Desktop, I was prompted an alert that "Local graph password has been changed".
That is strange, because I have not changed it...
It did not accept nor my previous password (the one I use for the server), nor the default 'neo4j', but could pass the alert because I could ignore this change until the next Graph start.
So I ignored it, and was prompted to enter the password to connect with the neo4j server. And this time, apoc were found.
I tried to close the neo4j desktop, quitting from all open projects, and relaunch. This time I was not asked to input the password for the local dbms. So, I assumed the to have restarted the next Graph, following the previous alert, and I was expected to be requested to input the password again.
Maybe the problem was here. So, to avoid future hiccups:
does neo4j reset the password of local dbms itself after a while or after certain conditions ?
after neo4j desktop closes, am I sure all server and open dmbs instances are properly shut down ? What does until the next Graph start actually mean ?
Plugins must be installed for each DBMS instance in Neo4j Desktop (there can be multiple DBMS instances in each project). Also, there can only be one active DBMS in Neo4j Desktop at a given time. Make sure that you have installed the plugin for the DBMS instance that you want to work with AND that DBMS is the one that is currently running. I'm guessing that you successfully installed the plugin for one DBMS, but tried querying with a different active DBMS that did not have the plugin.
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.
I have a 2016 access file, when I try to access this file with an SQL or Access datasource in visual studio I get the following error message:
Database schema could not be retrieved for this connection. Please make sure the connection settings are correct and that the database is online.
The database you are trying to open requires a newer version of Microsoft Access
I checked my database and I don't have any Large Number in it so I'm not sure what exactly is the problem.
It was working fine before I did some changes with a few Date/Time data type but I since changed all the Date/Time to Short Text. I'm not certain if it has any relation to the error message but it was the only change I've made before the error.
Can anyone help?
I had this problem and its stems from the use of new data fields.
Eliminating them alone did not do the trick. When you use one of the new field types it steps the version up to 16.7, which is not compatible with earlier access versions.
Note that you can get the version number with ? Currentdb.Version in the immediate window
I had to run the compact and repair routine in order to get the version to step down.
I've built and installed the "apoc" procedures according to the github page (The apoc-1.0.0-SNAPSHOT.jar file was copied into the plugins directory after the suerver was stopped, and then I started the server again) but when I try to call any of the procedures, I get an error message.
ex:
$ call apoc.help('search') ;
"There is no procedure with the name apoc.help registered for this
database instance. Please ensure you've spelled the procedure name
correctly and that the procedure is properly deployed."
I have come across the issue on both MacOs and Windows installations. I'm running Neo4j 3.0.0 as a server (locally on port 7474).
Have I missed any of the settings?
Thanks,
Babak.
I had to manually add this line to the .neo4j.conf file:
dbms.directories.plugins=/Applications/Neo4j\ Community\ Edition.app/Contents/Resources/app/plugins
(assuming that's where you dropped the APOC jar) and then restart the server.
(It's a little confusing as there's an option in the management app to configure this path, but it seems not actually to enable plug-ins on the server.)
For Windows users it should look like this:
dbms.directories.plugins=c:/Program\ Files/Neo4j\ CE\ 3.0.0/plugins
Assuming You have Neo4j installed at Neo4j CE 3.0.0. The import
Now (2023) the procedure seems to be different.
There are potentially two files needed to run APOC (https://community.neo4j.com/t5/neo4j-graph-platform/unable-to-see-some-apoc-load-functions/m-p/64154)
Some functions may be disabled by default and need to be enabled in the relevant database config e.g., dbms.security.procedures.allowlist=apoc.coll.,apoc.load.,apoc.periodic.*
Consider turning it on and after use off again for security.
I'm creating services on Windows XP.
I have to use a utility that we are using . The utility is making registration in the registry.
My question is that when I'm creating the service a folder name Enum is not created, which I saw was created for all other services.
Is it important ? For what I need it ?
Thanks
You should use the service APIs (CreateService) to create your service instead of manipulating the registry manually (or via your utility).
The format of the services registry has changed over the years and if you don't use the defined APIs, you may risk malfunctions (you're also going to require a reboot after the registry changes are made because the service controller has now way of knowing about your new service).
A common windows service doesn't need anything such as "Enum" Directory. It must be something specific in your applications. So if the directory wasn't created automatically, you need to write an installer for your service which creates this directory automatically, or create it manually.
You can use the command "instsrv" if you want to register a new service running under Windows XP.
