I need to index 80.000 nodes.
The max amount of nodes I can index per each cron run is 500.
I need to run crone 80.000 / 500 times to index the entire website.
How can I automatically schedule these runs (when a run is finished, the next run automatically should start)?
I don't have SSH access so I cannot use drush.
Thanks
Why don't you set a cronjob every 4 minutes or so? Just make sure that the interval between cronjobs is longer than the time it takes to run the cron script, so it won't overlap.
Did you try Poormanscron?
A module which runs the Drupal cron operation using normal browser/page requests instead of having to set up a crontab to request the cron.php script. The module inserts a small amount of JavaScript on each page of your site that when a certain amount of time has passed since the last cron run, calls an AJAX request to run the cron tasks. Your users should not notice any kind of delay or disruption when viewing your site. However, this approach requires that your site gets regular traffic/visitors in order to trigger the cron request.
All cron does is visit yoursite.com/cron.php
So you could use cron/schedule task/etc on a local machine.
To reiterate and clarify other answers: As long as you haven't explicitly blocked it in .htaccess or Apache configuration, you can trigger Drupal's cron.php simply by visiting yoursite.com/cron.php from any browser. You can also set up your local machine (or any other machine that has web access, really) to run its own cronjob which triggers your site's cron.php. This process varies from platform to platform, but for example, on most Linux systems, you could run crontab -e and add a line like this:
0 * * * * wget -O - -q -t 1 http://www.example.com/cron.php
# Run example.com's cron tasks at the beginning of every hour.
or possibly:
*/5 * * * * wget -O - -q -t 1 http://www.example.com/cron.php
# Run example.com's cron tasks at every five minute interval.
