Cron Jobs

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. Koha has many cron jobs in place that you can enable (search engine indexing, overdue notice generation, data cleanup and more), 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 cronjob entries for the most commonly-used cronjobs.

The locations below assume a dev install which puts the crons in misc/, if you have a standard install you may want to look in bin/ for these files if you cannot find them in misc/

Fronta rezervací

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

Vaše pořadí ve frontě rezervací

Required by: Holds Queue Report

Vybrané návrhy:

Popis:

  • Chcete-li vytvořit tuto zprávu, musíte mít běžící cron (plánovač) na „Build Holds Queue“. Tato plánovaná úloha je skript, který by měl být spouštěn pravidelně, pokud váš knihovní systém umožňuje čtenářům dávat rezervace na polici. Tento skript rozhodne, která knihovna by měla být zodpovědná za plnění daného požadavku na rezervaci.

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

    If you do not want all of your libraries to participate in the on-shelf holds fulfillment process, you should list the the libraries that *do* participate in the process here by inputting all the participating library’s branchcodes, separated by commas ( e.g. „MPL,CPL,SPL,BML“ etc. ).

    By default, the holds queue will be generated such that the system will first attempt to hold fulfillment using items already at the pickup library if possible. If there are no items available at the pickup library to fill a hold, build_holds_queue.pl will then use the list of libraries defined in StaticHoldsQueueWeight. If RandomizeHoldsQueueWeight is disabled ( which it is by default ), the script will assign fulfillment requests in the order the branches are placed in the StaticHoldsQueueWeight system preference.

    Například, pokud váš systém má tři knihovny, různých velikostí (malé, střední a velké) a chcete větší zátěž na plnění rezervací na větších knihovnách před menšími knihovnami, měli byste StaticHoldsQueueWeight nastavit takto „LRG, MED, SML „.

    Chcete-li zátěž na plnění rezervací rozprostřít rovnoměrně na celý knihovní systém, jednoduše zvolte RandomizeHoldsQueueWeight. Je-li tato předvolba zvolena, bude pořadí, ve kterém budou knihovny žádány aby plnily objednávky, náhodné při každé změně fronty.

    Leaving StaticHoldsQueueWeight empty is contraindicated at this time. Doing so will cause the build_holds_queue script to ignore RandomizeHoldsQueueWeight, causing the script to request hold fulfillment not randomly, but by alphabetical order.

Vyprší

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

Does: By default, this cron job will only automatically cancel 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.

Does: This script 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.
