Koha Hacks: How to Enable Plack on Koha Library System (Running On Ubuntu 20.04LTS)

Is your Koha server taking too long to catalog or checkout items? Before you break the bank and purchase a bigger server with bucket-loads of RAM and processing power, enable Plack instead – It will make your server much faster, and  you might just save yourself a lot of time and money!

How to Enable Plack in Koha Library System

Plack is “an interface between Perl web applications and web servers” and makes Koha’s modules persistant so that they don’t have to be loaded everytime they are needed. Plack makes Koha work faster – much, much faster. One test showed that it increased Koha’s processes by 25% and reduced the server load by 70% (this means Plack enables a server to handle the same computational processes with more than 2 times few resources as another server without Plack). 

Plack is included in Koha by default but sometimes it may need to be enabled (again check your About Koha page to see if it’s running or not).  Do the following:

sudo koha-plack --enable library
sudo koha-plack --start library
sudo systemctl restart apache2.service

Then check your Home > About Koha page. You should have “PSGI: Plack (deployment)” under Server Information if Plack is running and configured correctly.

Tweaking Your Koha Library Server

Pro Tip: You should regularly check Koha’s Home > About Koha page. It gives you a quick overview of your server information. If there are any errors, missing applications or dependencies that might be slowing down your server, they will show up here. Now, read on to find out how to make the most of Koha library system.

7 Reasons Why You Need an Integrated Library Management System

7 Reasons Why You Need an Integrated Library Management System

Running a library isn’t as simple and straightforward as many people I have encountered think. It’s more than just checking out books and putting them back on the shelf when they are returned. Librarians have to deal other complex, time-consuming responsibilities like acquisitions, cataloguing, inventory, budgets, reports and interlibrary loaning. Pen and paper won’t cut it, and using an excel spreadsheet is only marginally better than digging a trench using a caviar spoon.
