Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

Chapter 1. JBoss EAP 8.0 update methods
Copy link

You can update JBoss EAP 8.0 using the following methods:

  • JBoss EAP Installation Manager
  • Management CLI
  • Web console
  • RPM

From JBoss EAP  8.0 onward, the JBoss EAP server can be updated in either online or offline mode. These modes are supported by all the update methods.

  • Online update: You can update JBoss EAP directly from an online repository. You must have access to the Red Hat repositories or their mirrors to use this mode. This option always updates to the latest available JBoss EAP  8.0 update.
  • Offline update: You can update JBoss EAP from a local file-system. Use the offline update mode if you do not have online access to the Red Hat repositories or their mirrors. You will need to download the latest update and distribute it to your systems.

Depending on your requirements, choose one of the listed update methods. The following table provides a brief overview of each type of update method.

Chapter 2. Understanding channels in JBoss EAP
Copy link

The jboss-eap-installation-manager provides a streamlined and controlled pathway to access the most recent supported versions of JBoss EAP components. These streamlined and controlled pathways are called channels. A channel consists of a curated list of component versions (called channel manifest) and a collection of repositories used to resolve and retrieve those components. Each repository has a unique name (id) and a default Maven repository URL. The jboss-eap-installation-manager allows you to manage these channels effectively in both stand-alone and managed domain configurations.

You can update JBoss EAP periodically if new updates are available after you have downloaded and installed it.

Prerequisites

  • You have access to the internet.
  • You have created an account on the Red Hat customer portal and are logged in.
  • You have downloaded the jboss-eap-installation-manager.

In JBoss EAP 8.0, we have integrated the jboss-eap-installation-manager into the JBoss EAP server management model, allowing you to update and revert your remote server installations without the need to log in to the remote machine and use the jboss-eap-installation-manager from the operating system command line.

Note

If you are updating or reverting a local JBoss EAP installation, the jboss-eap-installation-manager is recommended instead of the Management CLI operations. However, you cannot use the jboss-eap-installation-manager to update or revert a remote JBoss EAP installation. In this case, use the Management CLI.

5.1. Prerequisite
Copy link

  • You have a JBoss EAP installed.

You can update your JBoss EAP server installation in a stand-alone server or a managed domain using the JBoss EAP Management CLI. The following steps outline the phases of the update process.

  • List update: Before preparing the server to be updated, the installer update command will check for all available updates and provide a list of updates ready to be applied to your JBoss EAP instance.
  • Prepare update: After confirming the available updates, the command will prepare a candidate server ready to be applied to your current installation. The candidate server is prepared in the server temporal directory, which is the directory represented by the file system path jboss.domain.temp.dir in a managed domain or jboss.server.temp.dir in stand-alone server mode. Once the preparation phase is completed, no further server preparations can be made. However, at any time, you can remove the prepared candidate server by cleaning up the manager cache. This action clears the cache and allows the preparation of a different installation, enabling you to start afresh. For more information, see Cleaning the installer.
  • Apply update: Once the candidate server is created, you can apply it to your instance by restarting your JBoss EAP server.

Procedure

  1. Launch the JBoss EAP Management CLI. 

    EAP_HOME/bin/jboss-cli.sh
    Copy to Clipboard Toggle word wrap

  2. Update JBoss EAP:

    1. Update JBoss EAP in a stand-alone server.

    2. Update JBoss EAP in a managed domain 

      [domain@localhost:9990 /] installer update --host=target-host
      Copy to Clipboard Toggle word wrap

  3. Restart your JBoss EAP server to complete the update process:

    Note

    You must ensure that no other processes are launched from the JBOSS_EAP/bin folder, such as JBOSS_EAP/bin/jconsole.sh and JBOSS_EAP/bin/appclient.sh, when restarting the server with the --perform-installation option. This precaution prevents conflicts in writing files that might be in use by other processes during the server’s update.

    1. Restart your JBoss EAP server in a stand-alone server. 

      [standalone@localhost:9990 /] shutdown --perform-installation

Additional resources

The JBoss EAP Management CLI allows you to easily view the history of all the updates and reverts that you applied on your JBoss EAP server. The Management CLI provides you with a comprehensive list of changes on your JBoss EAP server when you run the installer history command. These include updates, reverts and other modifications to the channel configuration. If you need more detailed information about a particular change, you can investigate futher it by appending --revision=<Installation state> to the command. This allows you to access the specific revision’s details and gain deeper insights into the changes to your JBoss EAP server.

6.1. Prerequisite
Copy link

  • You have a JBoss EAP server installed.

The following example describes how to use the JBoss EAP Management CLI to view the history of updates, reverts, or configuration changes on your JBoss EAP server in a stand-alone or a managed domain.

      Copy to Clipboard Toggle word wrap

You can revert updates applied to your JBoss EAP server using the Management CLI. To revert the changes applied to your JBoss EAP server, use the installer history command to view the previous versions of JBoss EAP installations on your server. Once you have confirmed the correct version of JBoss EAP you want to revert to, prepare a candidate server using the installer revert command. After preparing the candidate server, restart your JBoss EAP server to complete the revert process.

For more information see how to view the history of JBoss EAP installations on your server.

You can revert your JBoss EAP server installation in a stand-alone server or a managed domain using the JBoss EAP Management CLI. The following steps outline the phases of the revert process.

  • Prepare revert: In this phase, the JBoss EAP installation is prepared for the revert on the target machine. The candidate server is prepared in the server temporal directory, which is the directory represented by the file system path jboss.domain.temp.dir in a managed domain or jboss.server.temp.dir in stand-alone server mode. Once this phase is completed, no further server preparations can be performed on the same candidate server. However, you can clean the installation manager cache, which allows you to prepare a different installation if needed. For more information, see Cleaning the installer.
  • Apply revert: Once you have completed the revert process, restart your JBoss EAP server to apply the candidate server prepared to revert your installation.

9.5. Exporting a server snapshot
Copy link

You can export the installation manager configuration used by your JBoss EAP server to an archive file. This file can be used to recreate the same server configuration using the jboss-eap-installation-manager tool. This feature ensures easy replication of your server setup in other environments. For information see exporting a server snapshot using the jboss-eap-installation-manager.

One compelling use case for this capability is when you encounter a technical issue and need to seek support from the JBoss EAP team. By sharing the exported archive file with the support team, they can recreate your server configuration precisely as it is in your environment. This ensures that the support team can replicate the issue you are facing and provide targeted assistance, ultimately expediting the resolution process. You can also provide more details about your environment by following the steps in the JDR tool documentation.

Procedure

  1. Launch the Management CLI:

Chapter 11. Updating an RPM installation
Copy link

Before updating your current JBoss EAP instance by using the RPM installation method, check that your system meets certain setup prerequisites.

Prerequisites

  • You installed JBoss EAP server using RPM installation method.
  • The base operating system is up to date, and you get updates from the standard Red Hat Enterprise Linux repositories.

  • You are subscribed to the relevant JBoss EAP repository for the update.

    • If you are subscribed to a previous minor JBoss EAP repository, you have changed to the latest minor repository to get the update.
Important

For a managed domain, update the JBoss EAP domain controller before you update to a newer release of JBoss EAP.

An updated JBoss EAP 8.0 domain controller can still manage other JBoss EAP 8.0 hosts in a managed domain, as long as the domain controller is running the same or more recent version than the rest of the domain.

Procedure

  1. Update your current JBoss EAP version to the newer JBoss EAP version by issuing the following command in your terminal: 

    # dnf update
    Copy to Clipboard Toggle word wrap
  2. Enable new features in the updated release, such as new subsystems, by manually merging each .rpmnew file into your existing configuration files. The RPM update process does not replace any of your modified JBoss EAP configuration files, but it creates .rpmnew files based on the default configuration of your updated JBoss EAP instance.
