Chapter 19. Applying Patches


Red Hat JBoss Fuse supports incremental patching. FuseSource will supply you with easy to install patches that only make targeted changes to a deployed container.

19.1. Patching Overview

Incremental patching allows you apply targets fixes to a container without needing to reinstall an updated version of Red Hat JBoss Fuse. It also allows you to easily back the patch out if it causes problems with your deployed applications.
Patches are ZIP files that contain the artifacts needed to update a targeted set of bundles in a container. The patch file includes a .patch file that lists the contained artifacts. The artifacts are typically one or more bundles. They can, however, include configuration files and feature descriptors.
You get a patch file in one of the following ways:
  • Customer Support sends you a patch.
  • Customer Support sends you a link to download a patch.
  • Download a patch directly from the Red Hat customer portal.
The process of applying a patch to a container depends on how the container is deployed:
  • standalone—the container's command console's patch shell has commands for managing the patching process
  • fabric—patching a fabric requires applying the patch to a profile and then applying the profile to a container
    The management console is the recommended way to patch containers in a fabric. See chapter "Patching a Fabric" in "Management Console User Guide"for more information.
