where is conf/neo4j-wrapper.conf on windows installation - neo4j

Sorry for the newbie question, i see lots of references to conf/neo4j-wrapper.conf , but cannot find this anywhere on my windows server installation of Neo4j 2.1.2.
can somebody tell me where it is please?
thanks

You'll have to create the "conf" directory yourself.
I tried it on my windows machine before answering you, as I encountered the same problem initially.
In my case, I first created the directory
C:\Program Files (x86)\Neo4j Community\conf
and in there I created the files
neo4j.properties
neo4j-wrapper.conf
See Neo4j post here

I might be mistaken, but, I don't believe the Windows version puts an instance of that file on disk.
Given that neo4j.properties is in your actual graph DB directory (e.g. c:\\Neo4j\default.graphdb), you might try creating an instance of the file there and seeing what happens.
Or you could also try creating a conf/ directory from that same location and putting it in there.
I'm used to working with the Linux version, myself.
Let us know what you find!

How to enable jvm remote debugging in neo4j community edition windows and linux

I would like to actually debug the extension running the Neo4j server from within Eclipse.
Can anybody give me a hint on how to do that.
I see lots of references to conf/neo4j-wrapper.conf , but cannot find the file neo4j-wrapper.conf anywhere on my windows(the same thing for linux) server installation of Neo4j 3.5.11. I just have neo4j.conf.
can somebody tell me where I can put the following please in which file?
wrapper.java.additional=-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005 -Xdebug-Xnoagent-Djava.compiler=NONE-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005
Any help would be appreciated.
Many Thanks.
neo4j-wrapper.conf was merged into neo4j.conf in neo4j version 3.1.
See: https://neo4j.com/developer/kb/manually-merging-neo4jwrapperconf-into-neo4jconf-in-neo4j-31/
So, in neo4j 3.1+, all config settings are in neo4j.conf.
Adding on to #Schwertfisch's answer, change suspend=n to suspend=y if you want to debug code that executes at startup, such as the constructor of a trigger. With suspend=y the VM waits until a debugger attaches before starting the application.
https://neo4j.com/docs/java-reference/current/server-debugging/
in file neo4j.conf
dbms.jvm.additional=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005

What is the location of the configuration file in Neo4J 3.2?

I just installed Neo4j 3.2.6 on Windows. I am trying to run apoc.load.json. I have moved the plugins folded. They really need to sort this out.
I run it and I'm getting this error:
Failed to invoke procedure apoc.load.json: Caused by:
java.lang.RuntimeException: Import from files not enabled, please set
apoc.import.file.enabled=true in your neo4j.conf
only one problem, there is no neo4j.conf.
Database starts fine. I can run other statement, just not APOC procedures.
Any ideas?
You can take a look in the Neo4j file location docs. According to these docs the neo4j.conf file location in Windows installations is:
<neo4j-home>\conf\neo4j.conf for zip installations
%APPDATA%\Neo4j Community Edition\neo4j.conf for desktop installation (installer)
For Neo4j Desktop:
C:\Users{user}\AppData\Roaming\Neo4j
Desktop\Application\neo4jDatabases\database-{YOUR DATABASE HERE}\installation-{version}\plugins
For Neo4j Desktop,
Click pull down menu of your project
Click "Open Folder" menu
Click "Configuration"
Then new window of explorer will be opened with the path with neo4j.conf file included, for example:
C:\Users\{user}\AppData\Local\Neo4j\Relate\Data\dbmss\dbms-3a5f5b9b-77b4-48cf-96f4-43aa81cce24b\conf\
If you are not able to find in other directions, you can try searching in the below path where I found my configuration located:
C:\Users\{user}\.Neo4jDesktop\neo4jDatabases\database-{YOUR DATABASE
HERE}\installation-{version}\conf
Hope it helps.
Even though the Neo4j documentation says that for windows desktop neo4j.conf file location is
%APPDATA%\Neo4j Community Edition\neo4j.conf, I couldn't find the file at that particular location.
I found the neo4j.conf file at below location :
{YOUR_NEO4J_DB_DIRECTORY}\neo4jDatabases\database-{SOME_VERSION_STRING}\installation-{YOUR_NEO4J_VERSION}\conf
Hope it helps someone!

Neo4j plugin : can't use the spatial procedures after installing neo4j spatial plugin

So I have neo4j3.1.4 community edition, and tried to put neo4j spatial plugin jar v0.24 file under the "E:\softwares\Neo4j CE 3.2.0\plugins" directory. "E:\softwares\Neo4j CE 3.2.0\" is my neo4j installation directory. I couldn't find any of th procedures of spatial from cypher through browser. But I seem to have done exactly what the manual told me.
Judging from the installation path I'd say you actually have Neo4j 3.2.0 running, no ? Anyway (shouldn't make a difference really), if you take the latest release from https://github.com/neo4j-contrib/spatial/releases/download/0.24-neo4j-3.1.1/neo4j-spatial-0.24-neo4j-3.1.1-server-plugin.jar, drop it into the plugins directory and then restart (don't forget that) Neo4j, things should work. You can verify if the spatial-procedures are there with a CALL dbms.procedures(). If not, please verify the neo4j.log file ... there are multiple messages about loading "geometry" related stuff in there if things go well (or you may see the reason it's not loading otherwise).
Also, and again judging from your installation directory, I think you may have used the Windows installer ? If so, the plugins directory is actually located at C:\Users\youruser\Documents\Neo4j\default.graphdb\plugins, not in the installation directory.
Hope this helps,
Tom

Cannot run Grails from command prompt

I’ve added a GRAILS_HOME environment variable, which points to the folder in which I extracted the Grails distribution zip, and I’ve added %GRAILS_HOME%\bin to my path. Yet after I open a new command prompt, the “grails” command is still not found. Does anyone have any clue as to why this is happening?
I’m running Grails 2.2 on Windows 7.
I have the same problem on Windows 7 64 bit and Grails version 2.*
By removing local neither maven repository nor installed plugins repository doesn't help.
I found - just set properties of %GRAILS_HOME%/bin/grails.bat and startGrails.bat as Run in compatibility mode: Windows XP (Service Pack 3).
To do that You need to have local PC Administrators rights.
/igors
have you create JAVA_HOME in there?
Maybe you are experiencing [STS-2530] Problem deploying Grails App if workspace path has a space. Jira shows the issue as resolved but it would not hurt to check that you do not have a space in your workspace path as it my trip up grails.
Do the following.
Go to your command prompt, execute the Path command. If everything has been set right your paths should show up as complete paths starting with C:... If the paths show up with the % sign that means your paths need to be set correctly. I did noticed that in your example you have used the forward slash - I am assuming that is a typo, because that will be a problem.
Another way to trouble shoot the issue is CD to the location C:\Grails\bin, execute the command grails.bat, if it executes you are in a good place that means you have to tweak your paths - following this path might give you a clue about other issues....
You might want to check the bin folder of your grails installation. The grails.bat file could be missing. I had this problem today and solved it by downloading the zip file again.

Windows x64 RabbitMQ install error with Erlang environment var (ERLANG_HOME)

I'm ask/answering this question because it hung me up & it's likely someone else will have the same problem.
Install of RabbitMQ x64 v2.8.6 on Windows Server 2008 x64.
After Erlang install using default install location to C:\Program Files\erl5.9.2, I'm attempting to start the server via running the rabbitmq-service.bat. Fail:
Please either set ERLANG_HOME to point to your Erlang installation
or place the RabbitMQ server distribution in the Erlang lib folder.
Problem is the .bat file does not have the correct subpath. with 5.9.2 (R15B02) version of erlang. My ERLANG_HOME directory is set correctly, but the script does not use it correctly for this version of Erlang, which, it appears to this Erlang noob to have a new subdirectory called "erts-5.9.2" which is causing the problems. Maybe someone intimate with these scripts can describe how to make this work correctly without the hack workaround I'm about to describe?
1- Set environment variable:
Variable name : ERLANG_HOME
Variable value: C:\Program Files (x86)\erl6.4
note: don't include bin on above step.
2- Add %ERLANG_HOME%\bin to the PATH environmental variable:
Variable name : PATH
Variable value: %ERLANG_HOME%\bin
This works well.
There are several RabbitMQ control .bat files on windows. Every one you use needs to get changed to reflect the Erlang path correctly. In this example, I'm editing the rabbitmq-server.bat because it's one of the easier ones... any of the .bat files you want to run will need this hack to get them to work, with the rabbitmq_service.bat file being the most involved to adjust.
editing that rabbitmq_server.bat file, you can see on about line 48 or so there's a check to see if the erl.exe is found, but the path isn't correct:
if not exist "!ERLANG_HOME!\bin\erl.exe" (
that path does not match the file structure for the 5.9.2 version of Erlang. I fixed this by simply removing this path check from about line 48 to 58, then, where the .bat actually makes a call to the erl.exe on about line 129 which reads:
"!ERLANG_HOME!\bin\erl.exe"
I simply hardcoded the path to my erl.exe:
"C:\Program Files\erl5.9.2\erts-5.9.2\bin\erl.exe"
With the pathing correct, the rabbitmq .bat files will run.
I had the similar issue, modifying ERLANG_HOME in .bat files did not work. Then I tried echo %ERLANG_HOME% in command prompt, that did not print the environment variable value(I could see that ERLANG_HOME environment variable has been created under advance system settings), that lead me to believe that I need to restart server for 64 bit installation of Erlang. After rebooting server, It worked like a charm. I hope this helps someone.
Just to share an up-to-date answer as of 2019: On Windows Server 2019, after setting up the environment variable, a restart is required to solve the problem.
I got into same kind of problem.
I solved it by doing three changes as given below.
Update Path variable "ERLANG_HOME" : "C:\Program Files\erl8.0" in Environment Variables.
Upadte "Path" variable "Path" : ";%ERLANG_HOME%\bin;"
Give urself FULL CONTROL permissions over "Program Files" in C drive.
It worked for me in this way.
This problem still occurs in Erlang 18.3 (erl7.3) and RabbitMQ 3.6.9 on Windows when upgrading from any older version of RabbitMQ to version 3.6.9. The solution as already stated here is to manually set ERLANG_HOME with 'setx -m ERLANG_HOME "C:\Program Files\erl7.3"' before starting the service.
What happens is that the RabbitMQ 3.6.9 installer removes the environment variable ERLANG_HOME from the system while removing the older version of RabbitMQ. Then, when it proceeds to the installation step, it does not put back the ERLANG_HOME variable. Then, the batch files that start up RabbitMQ cannot find Erlang. They try to find Erlang's home directory using "where.exe" but it always fails after an upgrade.
RabbitMQ's installer also does not kill all of the Erlang background processes, causing many of its files to be undeletable due to the Windows "file in use" problem. This leaves behind "files in use" in %APPDATA%\RabbitMQ and "C:\Program Files\RabbitMQ." These processes are "erl.exe," "erlsrv.exe," and "epmd.exe." The RabbitMQ installer should taskkill these processes after shutting down the RabbitMQ Windows service.
RabbitMQ is rather clunky on Windows.
Download Erlang or OTP - Only one Version of OTP should be installed
Download RabbitMQ installer
Install both exe file as Administrator
Set class path for Erlang. (Setting classpath is a bit troublesome, so follow these steps)
Set a new path with name ERLANG_HOME and value C:\Program Files\erl-23.1 (do not copy bin folder here)
Edit System "path" and add %ERLANG_HOME%\bin
Go to Start - Open rabbitmq command promt and run
rabbitmq-plugins enable rabbitmq_management
Navigate to localhost:15672
Use guest/guest to login
Interesting that this worked for you. There is record of a two bugs in Erl5.9.2 that cause an incomplete installation where %ERLANG_HOME%\bin is not installed.
Either of
* Installed 64bit erlang on 32bit machine
* "The program can't start because MSVCR100.dll is missing from your computer."
https://groups.google.com/d/topic/erlang-programming/wGtFLzapiQ0/discussion
Try 5.9.1 or any other version. They also mention making the future versions of the installer alert you if it fails.
I just had the same problem mentioned here. I installed otp_win64_R15B02 on a Windows 7 machine and everything worked perfectly, but I used the same installer on a Windows 2008 server and the bin directory was not created. I then uninstalled otp_win64_R15B02 and downloaded the otp_win64_R15B02_with_MSVCR100_installer_fix and the bin directory was created.
I suspect the reason it worked on my Windows 7 system is that I have Visual Studio installed and the required libraries were already available which allowed the otp_win64_R15B02 installer to work correctly.
Oh, and if you're installing Erlang to run RabbitMQ the RabbitMQ install will succeed with the broken installer but installing otp_win64_R15B02_with_MSVCR100_installer_fix after RabbitMQ will not work, just un-install and re-install RabbitMQ to resolve this.
Just give C:\Program Files\erl10.6\ not C:\Program Files\erl10.6\bin\erl.exe in the environment variable. If you open the server.bat file I came to know the issueenter image description here
I think this is encoding issue on windows.I see a correct value but I write echo %ERLANG_HOME% on console the value come with question mark. These steps fix it.
1.go environment variable window
2.edit ERLANG_HOME item
3.copy the value, open notepad and paste there
4.copy again on notepad and paste to edit window
5.apply and exit window
6.close command line tools and reopen
7.run rabbitmq bat file.
I solved it in a quick and dirty way,without naming path variables
I've opened the bat file and replaced every occurrence of
!ERLANG_HOME!\bin\erl.exe
with hard coded path for example might be diffrent path for you because of diffrent version
C:\Program Files\erl10.3\erts-10.3\bin\erl.exe
and replaced
%RABBITMQ_HOME%\escript\rabbitmq-plugins
with
C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.14\escript\rabbitmq-plugins
Even I was this problem. The issue was the environment variable ERLANG_HOME=c:\Program Files\erl9.0 which was never existed.
I cross checked the path. The correct path was c:\Program Files\erl9.3.
After correcting the
ERLANG_HOME=c:\Program Files\erl9.3
the problem solved. So, definitely it is a path issue.
In my case, it should be installed erlang using admin role running
If above solutions doesn't work for you then you can try following
Find another compatible version of erlang for your rabbit mq e.g. for rabbit 3.7.x erlang version 20.3.x to 22.0.x all are compatible .
Right click newly downloaded erlang version and from properties select the option to unblock the file .
Run the erlang with admin persssion .
Re run rabbit mq exe
