Keep your WSO2 products up-to-date with WUM

WSO2 Update Manager

We at WSO2 continuously improve our products with bug fixes, security fixes , and various other improvements. Every major release of our WSO2 products is followed by a series of periodic dot releases that roll up all these recent updates.

We want everyone evaluating, developing on, or preparing WSO2 products for production deployments to have the best experience — and especially not trip over a bug that has already been fixed! Therefore we recommend always to use the latest versions of our products.

Usually, we do dot releases once a month, once in two months, once in a quarter. But sometimes these releases can get delayed even further. Though we continuously improve our products, you have to wait for dot releases to gain access to those updates.

But with WUM, we are bridging this gap. WUM gives continuous access to WSO2 product updates. You will get access to latest updates as and when we release them.

What is WUM?

WUM is a command-line application which allows you to keep WSO2 products up-to-date. It determines which updates are new and relevant for your WSO2 products, downloads and installs them. WUM builds you a new product distribution with all the relevant updates, which is ready to deploy into your development or production environment. Note that WUM will not push updates into production — you have full control over when and how you want to such pushes to occur.

Updates are available for the following products and versions. We are in the process of adding more products and versions.

  • WSO2 Enterprise Service Bus 5.0.0
  • WSO2 Enterprise Service Bus 4.9.0
  • WSO2 Enterprise Service Bus Analytics 5.0.0
  • WSO2 API Manager 2.0.0
  • WSO2 API Manager Analytics 2.0.0
One important thing to note here is, that fresh WSO2 product distributions downloaded via the site or using WUM, are licensed under Apache 2. But the product distributions built by WUM with updates installed are licensed under WSO2 Update License 1.0. Therefore the updated product distributions are not licensed for use in production without a valid WSO2 subscription. Visit for more information about WSO2 subscription.

Local product repository

WUM maintains a local product repository in your machine, where it stores WSo2 product distributions. Whenever you update a product, WUM creates a new distribution with all these updates and stores it in this repository.
By default, WUM creates this repository in the user’s home directory, but you have the option to change this as well.

Search and add WSO2 products

Before you update any WSO2 product, you need to add the product to your local product repository. You can either download a product or add an already downloaded product. If you are not sure about what product name to use, you can use the ‘wum search’ command. If you run the search command without any arguments, it will list all the WUM supported WSO2 products.

$ wum search

wso2esb-4.9.0 - Enterprise Service Bus
What's next?
use "wum add <product>" to download a product
e.g "wum add wso2esb-5.0.0" to download Enterprise Service Bus 5.0.0

You can also search using keywords.

As I’ve explained earlier, WUM creates a new product zip file with all the updates installed. But if you want to check whether updates are available before you attempt to update, you can use the “check-update” command as follows.

$ wum check-update wso2esb-4.9.0
