13.4.3. Rollback the Application of a Patch in Zip Form Using the patch Command

Procedure 13.3. Rollback a patch from a JBoss EAP 6 server instance using the patch command

1. From the Management CLI, use the patch info command to find the ID of the patch that is to be rolled back.
   • For cumulative patches, the patch ID is the value of the first cumulative-patch-id shown in the patch info output.
   • One-off security or bug fix patch IDs are listed as the value of the first patches shown in the patch info output, with the most recently applied one-off patch listed first.
2. From the Management CLI, rollback the patch with the appropriate patch ID from the previous step.

   Warning

   Use caution when specifying the value of the --reset-configuration switch.

   If set to TRUE, the patch rollback process will also rollback the JBoss EAP 6 server configuration files to their pre-patch state. Any changes that were made to the JBoss EAP 6 server configuration files after the patch was applied will be lost.

   If set to FALSE, the server configuration files will not be rolled back. In this situation, it is possible that the server will not start after the rollback, as the patch may have altered configurations, such as namespaces, which may no longer be valid and have to be fixed manually.

   [standalone@localhost:9999 /] patch rollback PATCH_ID --reset-configuration=TRUE

   The patch tool will warn if there are any conflicts in attempting the rollback the patch. Refer to Section 13.4.1, “The patch Command” for available switches to re-run the command to resolve any conflicts.
3. Restart the JBoss EAP 6 server instance for the patch rollback to take effect:

   [standalone@localhost:9999 /] shutdown --restart=true
