The presentation will have two parts. The first will enumerate the various scheduled jobs (cronjobs) that your Koha system should be running, and the options available for each, including: Advanced Notices, Long Overdues, Overdue Notices, Fines, Message Queue Processing, and Zebra Indexing. The second part of the session will briefly explain what goes into writing a good cronjob, with a look at some examples and perl modules you can use to help. - Joe Atzberger

13. fines.pl
• No help
• No command-line options either
• sysprefs: finesMode, CircControl
• staff: fines rules, Calendar!
• TIP: run fines before notices

14. advance_notices.pl
• Like overdue notices, but before due
• “EnhancedMessagingPreferences” syspref
• Opt-In for individual patrons via OPAC

15. Building a good cronjob
• Documentation for use case!
• Good perl: use strict; use warnings;
• use Getopt::Long; # handle --options
• use Pod::Usage; # makes --help like perldoc
• internalize, like process_message_queue.pl
• test cases, dry run, operational feedback
