3.8. Software Collection cronjob Support

Procedure 3.8. Running periodic tasks with cronjobs

1. To use cronjobs for running periodic tasks, place a crontab file for your Software Collection in the /etc/cron.d/ directory with the Software Collection's name.
   For example, create the following file:

   %{?scl_prefix}crontab

2. Ensure that the contents of the crontab file follow the standard crontab file format, as in the following example:

   0 1 * * Sun root scl enable software_collection '/opt/provider/software_collection/root/usr/bin/cron_job_name/opt/provider/software_collection/root/usr/bin/cron_job_name/opt/provider/software_collection/root/usr/bin/cron_job_name/opt/provider/software_collection/root/usr/bin/cron_job_name/opt/provider/software_collection/root/usr/bin/cron_job_name/opt/provider/software_collection/root/usr/bin/cron_job_name'

   Copy to Clipboard Toggle word wrap
   where software_collection is the name of your Software Collection, and /opt/provider/software_collection/root/usr/bin/cron_job_name is the command you want to periodically run.
3. Add the file to your spec file of the Software Collection package:

   SOURCE2: %{?scl_prefix}crontab

4. Install the file into the system directory /etc/cron.d/ by adjusting the %install section of the Software Collection package's spec file:

   %install
   install -p -c -m 644 %{SOURCE2} $RPM_BUILD_ROOT%{?scl:%_root_sysconfdir}%{!?scl:%_sysconfdir}/cron.d/
