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.

Cron jobs

The locations below assume a development 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/

Holds queue

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

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.

    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.

    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.

    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.

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

إقتراح التردد : يومياً

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.

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.

Required by: finesMode system preference

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

    • 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.

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.

إقتراح التردد: ليلاً

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.

Batch delete patrons

Script path: misc/cronjobs/delete_patrons.pl

Does: deletes patron records in batch based on date not borrowed since, expired before, last seen, category code, or library branch.

Note

Dates should be in ISO format, e.g., 2013-07-19, and can be generated with date -d '-3 month' "+%Y-%m-%d".

Important

The options to select the patron records to delete are cumulative. For example, supplying both --expired_before and --library specifies that patron records must meet both conditions to be selected for deletion.

PARAMETERS

  • --not_borrowed_since Delete patrons who have not borrowed since this date.

  • --expired_before Delete patrons with an account expired before this date.

  • --last_seen Delete patrons who have not been connected since this date. The system preference TrackLastPatronActivity must be enabled to use this option.

Does: Updates the patron category of patrons matching the given criteria to another specified patron category. This can be used to convert child patrons from a child patron category to an adult patron category when they reach the upper age limit defined in the patron category.

This script replaces the j2a.pl script.

إقتراح التردد: ليلاً

DESCRIPTION

This script is designed to update patrons from one category to another using the criteria specified using command line arguments.

PARAMETERS

  • --too_old Update, if patron is over the upper age limit of their current patron category.

  • --too_young Update, if patron is below the minimum age limit of their patron category.

  • --fo=X|--fineover=X Update, if the total fine amount on the patron account is over X.

  • --fu=X|--fineunder=X Update, if the total fine amount on the patron account is below X.

  • --rb=date|regbefore=date Update, if the registration date of the patron is before the given date.

  • --ra=date|regafter=date Update, if the registration date of the patron is after the given date.

  • -d --field name=value Update, if the given condition is met. <name> has to be replaced by a column name of the borrowers table. The condition is met, if the the content of the field equals <value>.

  • --where <conditions> Update, if the SQL <where> clause is met.

  • -v|--verbose Verbose mode: Without this flag only fatal errors are reported.

  • -c|--confirm Commits the changes to the database. No changes will be made unless this argument is added to the command.

  • -b|--branch <branchcode> Update, if the home branch of the patron matches the <branchcode> given.

  • -f|--form <categorycode> Update, if the patron currently has this patron category.

  • -t|--to <categorycode> Update the patrons matching the criteria to this patron category.

USAGE EXAMPLES

"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.

DESCRIPTION

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.

    تحذير

    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.

    ملاحظة

    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.

USAGE EXAMPLES

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"

Updates patrons who do not have any messaging preferences set and who are enrolled since March 1st, 2022.

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.
