File listener process interrupted with server restart
what happens when a file listener is processing a request and server is restarted? after restart the same request will be processes again?
In our application file listener picks up a file reads it process it and finally send out a email communication. if server restarted when processing a request, after server restart will the mail communication be sent out?
Thanks in advance

I would think this needs to be designed carefully and on a case-by-case basis.
Here's two examples:
1) If your listener's job is to send out invitations, and the server is shut down in the middle, restarting the one you were on is ok, since it just means someone will receive two copies of the invitation which is no big deal, and is better than someone not getting any invitation.
2) If your listener's job is to cut and mail checks, and the server is shut down in the middle, restarting the one you were on could be really bad since someone might receive two checks.

Hi Shashikalavathi,
Have tried this?
What is the clean up operation you mentioned in the File Listener?
Hope, if the file listener operation is not successfully processed, then the file will remains in the same location.
Hence the file will be picked once the server is up again.
Thanks.

Hi Shashi,
you need to configure your file listener properly to handle the error situation. You need to set them in the "Error " tab of the listener rule form. Please refer the help article for details :https://community.pega.com/sites/default/files/help_v719/procomhelpmain.htm

Hi,
As Aruldevan said, the file will remain in the location, the listener can pick it up and proceed.
But this will again start from the beginning. as the requestor created for the initial process would have been cleared.
