I have created a node application that is for subscribing to an OPC-UA server and storing the data on our s3 bucket. I am using the node-opcua module for that purpose.
I am working on a Windows server via RDP and the node-opcua
module creates some files under %LOCALAPPDATA%\Temp
as part of the process and uses it. I am using pm2
to run the application and it is getting the path of those files via TMP
and TEMP
environment variables which are dynamically generated by the process itself.
When the Windows server restarts it delete those files and the location updates of the new file. I already have run pm2 save
and put the pm2 resurrect
command in the Batch file which has a shortcut in the windows startup to make sure the process automatically gets started.
The issue was that the pm2 process was resurrected but still throwing the error %LOCALAPPDATA%\Temp\{some_path} file not found
by the node-opcua
process which was running through pm2. I ran pm2 restart
manually but still didn't work out.

First I was thinking of it from the problem with the node-opcua module and thought about how can make it use the new system variables, but that was not in had as the process keeps making and deleting temporary files, so I need the pm2 to use the new system variable which has the updated path after system reboot and was not updating even after pm2 restart
.
So, for updating the variables I figured out two solutions:
- Either delete the old process and initiate a new pm2 process to run that application and put it in the batch file which is being called at server reboot
- Adds
pm2 restart {name} --update-variable
afterpm2 resurrect
and the system variables will be updated.
