Could not find handle.exe with Rabbit 3.8.3

[Sri Reddy]

I have upgraded my Erlang, RabbitMQ Server and RabbitMQ Client (C#) to the following versions:

RabbitMQ Server 3.8.3Erlang 22.3 and Client 6.0.0

I started the RabbitMQ Server and immidiately  see this error in the logs. I downloaded `handle.exe` and updated the path variable. Restarted the machine, but i still see this error. 

Please let me know if you need any more information?

What OS are you using? Do you have full privileges to install application?

See Environment Variable Changes on Windows [1]. You must reinstall the *Windows service* (not RabbitMQ itself) for environment variable values to be picked up by it.

I am using Microsoft Windows 10 Enterprise and have full privileges. I installed Erlang, RabbitMQ server without any problem. I tried to follow the steps mentioned in the link provided - 

• Start an administrative command prompt
• cd into the sbin folder under the RabbitMQ server installation directory (such as C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-{version}\sbin)
• Run rabbitmq-service.bat stop to stop the service
• Run rabbitmq-service.bat remove to remove the Windows service (this will not remove RabbitMQ or its data directory)
• Set environment variables via command line, i.e. run commands like the following:

  setx path="C:\Windows\Handle"

• Run rabbitmq-service.bat install
• Run rabbitmq-service.bat start

No luck. And i can see that handle.exe is working from path, as I can run it from command line. Not sure, what else should i check.

Are you configuring PATH or other environment variables for the same user that installed RabbitMQ? (used to run the Windows service)

 

Rabbitmqctl.bat eval 'os:getenv().'

 

Will print all environment variables as seen by the server. On other OSes it will also include the user, I am not sure about Windows. But that will give you more data to compare anyway.

I configured PATH for the current user. Also, I have tried with updating the other env variables.

But, I still get the same error. 

I tried to run the command you mentioned and get the following syntax error:

C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.8.3\sbin>Rabbitmqctl.bat eval 'os:getenv()'

Error (argument validation): "syntax error before: "

Arguments given:

        eval 'os:getenv()'

“The current user” does not answer my question, I’m afraid. It has to be the same user that *runs RabbitMQ*,

which is not necessarily “the current one”.

 

In your eval line, you are missing the dot in eval 'os:getenv().'

Yes, it is important since you are executing an Erlang function via rabbitmqctl.

Hi Sri,

• Please remove the PATH changes you have made
• Save handle.exe to C:\Windows\system32
• Log in as the admin user you used to install RabbitMQ and open the "RabbitMQ Command Prompt (sbin dir)" item
• Use the set command to ensure your PATH changes have been reverted
• Ensure that you can run handle from this command prompt
• Remove and re-install the RabbitMQ windows service

Let us know if this resolves your issue.

Thanks,

Luke

Hi Liuke,

Thanks for your suggestion. It is working now. But, I do see these messages though

Not sure, what would be the reason for this?

[Luke Bakken]

Hello,

That is a known issue with handle.exe. Sometimes it does not produce the expected output. I have never been able to reproduce it, however.

Thanks,

Luke

[Sri Reddy]

Thanks Luke for responding. Hope this will not impact negatively on performance or anything. Right?
