JPrc Cron is a Joomla package (a component and a plugin) for Cron Jobs Management and Scheduling.
Its purpose is to simulate cron jobs through Joomla front end interface at preset periods of time for users who either don't have access to the server crontab/cPanel or don't want to use it for any purpose.
It is launched at the preset time only if your site gets visits in place. Each time a user or spider accesses your public site you will have the cron running. Eg if you set 3:00am, it might run 3:10am (according your site traffic).
If you need a solution to run, even if there's no visit, you need a server side solution to run within regular and fixed periods of time.
*** This software is a based in venerable JCron, updated for Joomla! 2.5 and 3.0 ***
Installation & Upgrading
Please, install it using the default Joomla procedure.
Note: to execute the cron jobs, it uses the PHP exec() function, so your provider must have it enabled to run a command. In the other hand, you can also work only calling Urls.
Please, remember to enable the plugin. After that, you can create your first Job.
These are the Job parameters:
- Task name
- Task types: SSH Command / Web Address fopen() Web Address fsockopen() / Plugin / Curl - Experimental
- Command to Run
- Run at: Minute(s)/ Hour(s)/ Day(s)/ Months(s)/ Weekday(s)
- UNIX Crontab
- Enable logs
- Last Run Time
- Last Run Log Text
These are the Component parameters:
- Enable CRON RUN
- Send Cron Logs to Email
- Activate Email Logs
- Enable Database Logs
About Backup Usage - Experimental
The Curl method is not ready for production usage to create backups:
- A backup can take anywhere from 10 seconds to 10 hours, beyond the usual Apache 5' session.
- The page load will be delayed for that long when the plugin is running.
- Relying on site access to run the backup is extremely dangerous and consistently leads to corrupt backup archives, inconsistent database backups or even ever-looping backup jobs
