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.

Esempio di crontab

Un esempio di crontab di Koha si trova in misc/cronjobs/crontab.example

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

Copia di sicurezza

Daily backup

Script path: misc/cronjobs/backup.sh

Does: creates a daily backup of the Koha database.

Frequenza consigliata: giornaliera

Circolazione

Holds queue

Script path: misc/cronjobs/holds/build_holds_queue.pl

Does: updates holds queue report

Required by: Holds queue report

Frequenza consigliata: ogni 1-4 ore

Descrizione:

  • Si tratta di uno script che dovrebbe essere eseguito periodicamente, se la vostra biblioteca permette agli utenti di richiedere prenotazioni a scaffale. Questo script decide quale biblioteca deve incaricarsi di soddifare una data richiesta di prenotazione.

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

    Se non vuoi che le tue biblioteche partecipino al processo di assegnazione di prenotazioni, *devi* comunque elencare qui le biblioteche che vi prendono parte, con una lista di codici di biblioteca separate da virgola (es.: «MPL,CPL,SPL,BML» ecc. ).

    Per default, la coda delle prenotazioni funziona in modo che il sistema prima tenta di soddisfare una prenotazione utilizzando copie che sono già presso la biblioteca del ritiro. In mancanza, build_holds_queue.pl userà la lista di biblioteche definite in StaticHoldsQueueWeight. Se RandomizeHoldsQueueWeight non è attiva (come da default), lo script assegnerà le richieste in base alla preferenza di sistema StaticHoldsQueueWeight.

    Per esempio, se il tuo sistema ha tre biblioteche, di varia dimensione (piccola, media e grande) e vuoi che il processo di assegnazione prenotazioni usi prima la alla grande biblioteca e poi le piccole, potresti impostare la preferenza di sistema “StaticHoldsQueueWeight” a «LRG,MED,SML».

    Se vuoi che il carico delle prenotazioni venga suddiviso equamente tra le varie biblioteche del sistema, abilita la preferenza di sistema RandomizeHoldsQueueWeight. Quando è attiva, l’ordine delle biblioteche verrà rigenerato casualmente ogni volta che viene creata la loro lista.

    Lasciare vuota la preferenza di sistema StaticHoldsQueueWeight è controindicato. Se fosse, lo script build_holds_queue script ignorerà RandomizeHoldsQueueWeight e processerà le richieste di prenotazione per ordine alfabetico, non a caso.

Expired holds

Script path: 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.

It is possible to add a cancellation reason with the –reason parameter. Use the cancellation code from the HOLD_CANCELLATION authorized value category

Frequenza consigliata: giornaliera

Unsuspend holds

Script path: 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.

Frequenza consigliata: giornaliera

Multe

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.

Richiesto dalla preferenza di sistema: finesMode

Frequenza consigliata: notturna

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

    • output 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.

Frequenza consigliata: notturna

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.

Nota Le multe non verranno attribuite durante le feste.

Long overdues

Percorso dello script: misc/cronjobs/longoverdue.pl

Che cosa fa: permette di specificare i ritardi necessari per cambiare lo stato di “smarrito” di un elemento ad un valore differente. Opzionalmente addebita gli elementi smarriti, utilizzando il prezzo di sostituzione registrato nel record di ciascun elemento.

Frequenza consigliata: notturna

Nota

Staff can control some of the parameters for the longoverdue cron job with the DefaultLongOverdueLostValue and DefaultLongOverdueChargeValue preferences.

Track total checkouts

Script path: misc/cronjobs/update_totalissues.pl

Che cosa fa: aggiorna il campo biblioitems.totalissues nel database con il il totale aggiornato dei prestiti basandosi sulle statistiche dello storico prestiti.

Frequenza consigliata: notturna

Avvertimento

Se l’ora sul server del database non coincide con l’ora sul server di Koha, bisogna tenerne conto e probabilmente utilizzare l’opzione –since, invece dell’opzione –interval, per l’aggiornamento incrementale.

Nota

Questo cron job può essere usato in caso di problemi di performance. Altrimenti usare la preferenza di sistema UpdateTotalIssuesOnCirc.

ESEMPI DI USO

«update_patrons_category.pl»

«update_patrons_category.pl» -b=<branchcode> -f=<categorycode> -t=<categorycode> -c» (Processes a single branch, and updates the patron categories from category to category)

«update_patrons_category.pl» -f=<categorycode> -t=<categorycode> -v» (Processes all branches, shows all messages, and reports the patrons who would be affected. Takes no action on the database)

Update patrons” messaging preferences

Script path: misc/maintenance/borrowers-force-messaging-defaults.pl

Does: updates patrons” messaging preferences to the default values set in the patron categories.

Messaging preferences defaults are automatically set when adding a new patron or when importing patrons with the patron import tool. However, if you import patrons directly in the database, these messaging preferences will not be set.

There is no suggested frequency. This is a tool to be used when needed, although if you regularly import patrons directly in the database (through a third-party, for example), you can add it to your crontab.

DESCRIZIONE

If the EnhancedMessagingPreferences system preference is enabled after borrowers have been created in the DB, those borrowers won’t have messaging transport preferences default values as defined for their borrower category. So you would have to modify each borrower one by one if you would like to send them “Hold Filled” notice for example.

This script creates/overwrites messaging preferences for all borrowers and sets them to default values defined for the category they belong to (unless you use the options -not-expired or -no-overwrite to update a subset).

PARAMETERS

  • –doit

    Update the patrons. The script will not update patrons” messaging preferences without this option. It will only list the patrons who would have been updated.

  • –not-expired

    Only update patrons who are still active (whose files are not yet expired).

  • –no-overwrite

    Only update patrons without any messaging preferences. This option will skip patrons who have already set their preferences.

  • –category

    Only update patrons from the specified category.

    Avvertimento

    This option cannot be repeated.

    For example:

    borrowers-force-messaging-defaults.pl --doit --category PT --category B

    will only update patrons from category B (the last category specified).

  • –since

    Only update patrons enrolled since the specified date.

    Nota

    This option can use specific or relative dates.

    For example:

    borrowers-force-messaging-defaults.pl --doit --since "2022-07-12"

    will only update patrons enrolled since July 12, 2022.

    And:

    borrowers-force-messaging-defaults.pl --doit --since `date -d "1 day ago" '+%Y-%m-%d'

    will only update patrons enrolled since yesterday.

ESEMPI DI USO

borrowers-force-messaging-defaults.pl --doit

Updates all patrons to give them the default messaging preferences values from their respective category.

borrowers-force-messaging-defaults.pl --doit --not-expired

Updates all patrons whose memberships are not expired to give them the default messaging preferences values from their respective category.

borrowers-force-messaging-defaults.pl --doit --category PT

Updates all patrons in the PT category to give them the default messaging preferences for that category.

borrowers-force-messaging-defaults.pl --doit --no-overwrite --since "2022-03-01"

Daemons

Daemons are continuously running tasks that help support Koha operation. Your database and web-server 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.
