[Koha] Koha 16.05 - Holds Script - Run Frequency

[Craig Butosi]

Hi Liz,

Ah, okay. It's clearer to me now how to edit crons in the .hourly, .daily folders. I thought it might have had something do with commenting out extant entries and moving them elsewhere - thanks for clarifying! If " build_holds_queue.pl " has nothing to do with posting holds to the "Holds to Pull" page, then I won't touch it.

I had a strange report of a student placing a hold recently, but nothing appearing on the "Holds to Pull" page (we've had no problems with our hold system to date, which has been running since September). My first thought was possible lag time between the hold request itself and a holds-related script running; but, this issue may be a case where the student didn't place a hold correctly, or something else. I'll investigate further.

Many thanks,

Hi Craig,
The cron job is run from files are in /etc/cron.hourly/koha-common for a package install.

Note that "build_holds_queue.pl" doesn't affect the holds to pull. It only affects the hold queue.

To change the frequency, you could comment out the job in /etc/cron.hourly/koha-common, adding an octothorpe at the beginning of the job like

# koha-foreach --enabled
/usr/share/koha/bin/cronjobs/holds/build_holds_queue.pl

and then create one in the /etc/cron.d/koha-common like

*/15 * * * * koha-foreach --enabled
/usr/share/koha/bin/cronjobs/holds/build_holds_queue.pl

very much like the process_message_queue.pl entry. This will run the job every 15 minutes, at 00, 15, 30, and 45. To change the interval, swap out the the 15 in */15 for your desired interval.

On a recent debian(8)/ubuntu(16), you can check the cron log super easily with sudo systemctl status cron

I hope this helps!

Cheers,
Liz

By 'processing' I mean when a patron clicks on "Place Hold" from the OPAC, and then that request gets entered into the "Holds to Pull" screen in the staff client. I see in directory /etc/koha/cron.hourly/ there is a script called "build_holds_queue.pl". Is this the one?

Are there any issues will running this script more frequently than every hour? (We are a library with a user base of about 600, and with a collection of about 50,000 items; by most standards a small library).
