Patching a running instance
The newest version of the JBoss Application Server comes with a patching utility that al-
lows you to automatically update parts of the server with newer versions. Currently, the
patching is done using a CLI. Any patch can be reverted, and the administrator is able to
track the history of patches.
A patch can be applied by simply calling the patch apply <file path>
(without -) command. A complementary command is patch rollback --
patch-id = id , a patch-rollback command. To obtain information about the installed
patches, simply call patch info . Patches are distributed by teams responsible for spe-
cific WildFly subsystems. Visit their websites if you need a patch for a specific module.
