Running the scheduler
======================

Since version 6 of SeedDMS a scheduler is implemented which runs
scheduled tasks. Such tasks must be implemented in an extension
and can be scheduled by the administrator within the user interface.

In order to check frequently for tasks ready to run, a system cron job
must be installed. On Linux this can be done by adding the following line
to the crontab

*/5 * * * * /var/www/seeddms60x/seeddms/utils/seeddms-schedulercli --mode=run

(Of course you need to change the path to `seeddms-schedulercli`)

This will install a cronjob running every 5 minutes. `seeddms-schedulercli` will check
for tasks ready to run and execute them in that case. You can decrease the time between
two calls of the cronjob, but keep in mind that seeddms tasks may take longer and
are being started again before the previous task has been ended.

If the configuration file of SeedDMS is not found, its path can be passed
on the command, though this should not be needed in a regular installation
obeying the directory structure of the quickstart archive.

*/5 * * * * /var/www/seeddms60x/seeddms/utils/seeddms-schedulercli --config /var/www/seeddms60x/seeddms/conf/settings.xml --mode=run

For testing purposes it may be usefull to run `seeddms-schedulercli` in list mode.

seeddms-schedulercli --mode=list

This will just list all tasks and its scheduled exection time. Tasks ready to run,
because its scheduled execution time is already in the past will be marked with
a `*`. Tasks which are disabled will be marked with a `-`.

Executing `seeddms-schedulercli` in `dryrun` mode will behave just like in `run` mode
but instead of running the task it will just issue a line.

Instead of running utils/seeddms-schedulercli you may as well access
op/op.Cron.php which also runs all scheduled tasks. On Linux you do this
by setting up a cronjob like

*/5 * * * * wget -q -O - "http://<your domain>/op/op.Cron.php"
