Cron jobs and daemons

Koha is supported by a number of background tasks. These tasks can either be periodically executed tasks (cron jobs) or continuously running tasks called daemons.

A cron job is a Linux command for scheduling a command or script on your server to complete repetitive tasks automatically. Scripts executed as a cron job are typically used to modify files or databases; however, they can perform other tasks that do not modify data on the server, like sending out email notifications.

A daemon is a Linux command that is typically started when the system is booted and runs in the background doing some function. The database used by Koha (either MySQL or MariaDB) is a daemon as is the web server (typically Apache).

Koha has many cron jobs in place that you can enable (search engine indexing, overdue notice generation, data cleanup and more), and a few daemons. This chapter will explain those for you.

Crontab example

An example of a Koha crontab can be found in misc/cronjobs/crontab.example

The example includes sample boilerplate cron job entries for the most commonly-used cron jobs.

Does: updates holds queue report

Required by: Holds queue report

اقتراح التردد: كل 1-4 ساعة

وصف:

  • السكربت الذي يجب تنفيذ النظام بشكل دوري أذا مكتبة النظام تسمح للمستعيرين بوضعة على رف الحجوزات. هذا السكربت يقرر ماإذا كانت المكتبة يجب أن تكون مسؤولة عن تحقيق طلب حجز معين.

    It's behavior is controlled by the system preferences StaticHoldsQueueWeight and RandomizeHoldsQueueWeight.

    إذا كنت لا تريد مشاركة كل مكتباتك في عملية ملء الحجوزات على الرف، يجب عليك إدراج المكتبات التي *تقوم* بالمشاركة في هذه العملية هنا عن طريق إدخال رموز فروع كل المكتبات المشاركة مفصولة بفواصل (مثال: "DPB، LC ، SPL، BML، الخ.)

    افتراضياً، سيتم توليد صف الحجوزات لكي يحاول النظام ملء الحجز أولًا باستخدام المواد الموجودة بالفعل في مكتبة الالتقاط إذا أمكن. في حالة عدم وجود مواد متاحة في مكتبة الالتقاط لملء حجز، سيقوم hold, build_holds_queue.pl عندئذ باستخدام قائمة المكتبات المعرفة في StaticHoldsQueueWeight. إذا تم إيقاف RandomizeHoldsQueueWeight ( وهو الافتراضي)، سيقوم النص بتعيين طلبات الملء بترتيب المكتبات الموجودة في التفضيل StaticHoldsQueueWeight.

    على سبيل المثال نظامك يتكون من ثلاث مكتبات، باحجام مختلفة (صغيرة ،

    إذا ما أردتَ أن تقوم بنشر عبء الحجوزات بالتساوي في نظام مكتبتك. ببساطة مكِّن التفضيل RandomizeHoldsQueueWeight . فعندما يكون هذا التفضيل ممكَّناً، فإن الترتيب الذي سيطلب من المكتبات إنجازحجز لمواد على الرف سيكون عشوائياً في كل مرة يتم إعادة توليد القائمة.

    من غير المستحسن ترك التفضيل StaticHoldsQueueWeight فارغاً في هذا الوقت. لأن ذلك سيؤدي إلى أن يقوم نص build_holds_queue بتجاهل التفضيل RandomizeHoldsQueueWeight، مما سيتسبب في أن يقوم النص بطلب ملء الحجوزات بالترتيب الأبجدي وليس عشوائيًا.

Expired holds

مسار النص: misc/cronjobs/holds/cancel_expired_holds.pl

Does: cancels holds where the user has set an expiration date. If the library is using the ExpireReservesMaxPickUpDelay and ExpireReservesMaxPickUpDelayCharge preferences then this script will also cancel holds that have been sitting on the hold shelf for too long and will (if the library does) charge the patron for not picking up the hold.

إقتراح التردد : يومياً

Unsuspend holds

مسار النص: misc/cronjobs/holds/auto_unsuspend_holds.pl

Does: checks to find holds that should no longer be suspended and removes the suspension if the AutoResumeSuspendedHolds preference is set to 'allow'. This puts the patron back in to the queue where they were when the hold was suspended.

إقتراح التردد : يومياً

غرامات

مسار السكربت: misc/cronjobs/fines.pl

Does: calculates and charges (or increments) overdue fines per item to patron accounts. The fine calculation is done using the grace period, fine interval, fine amount and other parameters from the circulation and fines rules.

مطلوب بواسطة: التفضيل finesMode

إقتراح التردد: ليلاً

Note If the Koha system preference 'finesMode' is set to 'production', the fines are charged to the patron accounts. If set to 'test', the fines are calculated but not applied.

Note Fines will not be applied on a holiday.

PARAMETERS - -h|--help

get help message

  • -l|--log log the output to a file (optional if the -o parameter is given)

  • -o|--out ouput directory for logs (defaults to env or /tmp if the directory does not exist)

  • -v|--verbose verbose mode

  • -m|--maxdays how many days back of overdues to process this can improve performance by simply the number of records that need to be processed. It can be safe to limit the overdues processed to those under X days overdues given that circulation policy often caps fines at a maximum after a number of days.

Static fines

Script path: misc/cronjobs/staticfines.pl

Does: charges a single static fine for any/all overdues a patron currently has outstanding. The charge amount is either defined on the command line per borrower category or will use the circulation rules associated with the oldest overdue item the patron has currently checked out (for the first fine period only) Once charged, the fine is static: No new fines will be added until the existing fine is paid off in full.

إقتراح التردد: ليلاً

Note If the Koha system preference 'finesMode' is set to 'production', the fines are charged to the patron accounts. If set to 'test', the fines are calculated but not applied.

Note Fines won't be applied on a holiday.

Warning

If the time on your database server does not match the time on your Koha server you will need to take that into account, and probably use the --since argument instead of the --interval argument for incremental updating.

Note

This cronjob can be used if there is a performance concern. Otherwise, use the UpdateTotalIssuesOnCirc System Preference.

Daemons

Daemons are continuously running tasks that help support Koha operation. Your database and webserver are run as daemons. Newer versions of Koha start two different daemons for most koha instances:

  • zebra - this is the index server

  • koha-indexer - this daemon updates the index server with new and modified data (biblios and authorities)

These daemons are started by the script /etc/init.d/koha-common.

Zebra indexer daemon

Script path: /usr/sbin/koha-indexer (invoked from /etc/init.d/koha-common)

The koha-indexer script invokes rebuild_zebra.pl in daemon mode. In this mode, the script will run continuously and check the database for new or modified data every 30 seconds. New or modified records are then sent to Zebra for indexing, which only takes a second or so. The advantage of this approach is a search system which is much more responsive to changes, compared to the cron job approach.
