Cron is a time-based job scheduler. DBSync uses cron to schedule jobs to run periodically at fixed times, dates or intervals.
The cron is a long-running process that executes commands at specific dates and times. You can use this to schedule activities, either as one-time events or as recurring tasks.
Timing Syntax
Cron determines how often and when the cron job is going to run.
It consists of five parts:
- Minute
- Hour
- Day of month
- Month
- Day of week
Examples based on the above "commands to execute"
This cron job will run every minute, all the time
* * * * * [command]
This cron job will run at minute zero, every hour (i.e. an hourly cron job)
0 * * * * [command]
This will run once a month, on the second day of the month at midnight (i.e. January 2nd 12:00am, February 2nd 12:00am etc.)
0 0 2 * * [command]
Add these 2 commands in system.properties
log.maxcount=
log.cleaner.cron =
