Cron (Scheduled Task) for Notifications #

Notification cron is used to send periodic notifications. Document expiry notifications will depend on this scheduler.

To trigger the scheduler you need to run the following file

(IceHrm Root)/app/cron.php

Setting up Linux Cron #

In a Linux environment, a cron should be set up to run every 10 minutes.

This can be done by placing the following line in your crontab. Depending on your server you can edit crontab sudo vi /etc/crontab

or you can use crontab -e command

/10 * (IceHrm Root)/app/cron.php

Make sure that (IceHrm Root)/app/cron.php file is executable.

For setting up the windows scheduler please check :
