9.4.1. The Patch Management System

The JBoss EAP 6 patch management system is used to apply downloaded zip patches to a single JBoss EAP 6 server. It can be accessed either through the Management CLI by using the patch command, or through the Management Console. The patch management system cannot be used to automatically patch JBoss EAP 6 server instances across a managed domain, but individual server instances in a managed domain can be patched independently.


JBoss EAP 6 server instances which have been installed using the RPM method cannot be updated using the patch management system. Refer to Section 9.5, “Patching an RPM Installation” to update RPM-installed JBoss EAP 6 servers.


The patch management system can only be used with patches produced for versions of JBoss EAP 6.2 and later. For patches for versions of JBoss EAP prior to 6.2, you should instead refer to the relevant version's documentation available at
In addition to applying patches, the patch management system can provide basic information on the state of installed patches, and also provides a way to immediately rollback the application of a patch.
When applying or rolling back a patch, the patch management system will check the modules and other miscellaneous files that it is changing for any user modifications. If a user modification is detected, and a conflict-handling switch has not been specified, the patch management system will abort the operation and warn that there is a conflict. The warning will include a list of the modules and other files that are in conflict. To complete the operation, it must be retried with a switch specifying how to resolve the conflict: either to preserve the user modifications, or to override them.
The table below lists the arguments and switches for the Management CLI patch command.
Table 9.1. patch Command Arguments and Switches
Argument or Switch Description
apply Applies a patch.
--override-all If there is a conflict, the patch operation overrides any user modifications.
--override-modules If there is a conflict as a result of any modified modules, this switch overrides those modifications with the contents of the patch operation.
--override=path(,path) For specified miscellaneous files only, this will override the conflicting modified files with the files in the patch operation.
--preserve=path(,path) For specified miscellaneous files only, this will preserve the conflicting modified files.
--host=HOST_NAME Available in domain mode, this specifies the host that the patch operation will be performed on.
info Returns information on currently installed patches.
history Returns information on the patching history.
rollback Rollsback the application of a patch.
--patch-id=PATCH_ID Required for rollback, the ID of the patch to rollback.
--reset-configuration=TRUE|FALSE Required for rollback, this specifies whether to restore the server configuration files as part of the rollback operation.
--rollback-to If the patch to rollback is an individual (one-off) patch, using this argument specifies that the rollback operation will also rollback all other one-off patches that have been applied on top of the specified patch.
