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.

Circulación

Fila de reservas

Ruta del script: misc/cronjobs/holds/build_holds_queue.pl

Qué hace: actualiza el informe de fila de reservas

Requerido por: Informe de fila de reservas

Frecuencia sugerida: cada 1-4 horas

Descripción:

  • Un script que se debe ejecutar periódicamente si su sistema de bibliotecas permite a los usuarios hacer reservas. Este script decide qué biblioteca debe ser responsable del cumplimiento de una solicitud de reserva dada.

    Su comportamiento está controlado por las preferencias del sistema StaticHoldsQueueWeight y RandomizeHoldsQueueWeight.

    Si no desea que todas las bibliotecas participen en el proceso de satisfacer reservas, se deberán incluir las bibliotecas que *sí* participan introduciendo los códigos de sucursal de todas las bibliotecas participantes, separados por comas ( por ejemplo «MPL,CPL,SPL,BML» etc. ).

    Por defecto, la fila de reservas será generada de forma que el sistema intentará primero cubrir las reservas utilizando ejemplares disponibles en la biblioteca de retiro de ser posible. Si no hay ejemplares disponibles para cubrir la reserva, build_holds_queue.pl utilizará la lista de bibliotecas definida en StaticHoldsQueueWeight. Si RamdomizeHoldsQueueWeight está deshabilitada (comportamiento por defecto), el script asignara los pedidos de cobertura en el orden de ubicación de las sucursales en la preferencia del sistema StaticHoldsQueueWeight.

    Por ejemplo, si su sistema cuenta con tres bibliotecas, de diferentes tamaños ( pequeño, mediano y grande ) y quiere que la carga de cumplimiento esté en las bibliotecas más grandes más que en las bibliotecas más pequeñas, usted querría que StaticHoldsQueueWeight fuese algo así «LRG,MED,SML».

    Si quiere que la carga de cumplimiento se extienda por igual por todas las bibliotecas del sistema, sólo tiene que activar RandomizeHoldsQueueWeight. Cuando esta preferencia del sistema está activada, el orden en el que las bibliotecas se les pedirá que satisfagan una reserva se asignará aleatoriamente cada vez que se vuelve a generar la lista.

    Dejar StaticHoldsQueueWeight vacío está contraindicado. Si lo hace, hará que el script build_holds_queue ignore RandomizeHoldsQueueWeight, provocando que el script solicite que se satisfaga las reservas no al azar, sino por orden alfabético.

Expired holds

Ruta del script: 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.

Frecuencia sugerida: diaria

Unsuspend holds

Ruta del script: 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.

Frecuencia sugerida: diaria

Multas

Ruta del script: 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.

Requerido por: preferencia del sistema finesMode

Frecuencia sugerida: todas las noches

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.

Frecuencia sugerida: todas las noches

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.

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.
