Java Policy Agents 2023.9

Upgrade

For information about upgrade between supported versions of Java Agent, refer to ForgeRock Product Support Lifecycle Policy | IG and Agents.

This section describes how to upgrade a single Java Agent instance. To upgrade sites with multiple Java Agent instances, one by one, stop, upgrade, and then restart each server individually, leaving the service running during the upgrade.

Java Agent supports the following types of upgrade:

  • Drop-in software update:

    Usually, an update from a version of Java Agent to a newer minor version, as defined in Release naming. For example, update from 2023.3 to 2023.6 can be a drop-in software update.

    Drop-in software updates can introduce additional functionality and fix bugs or security issues. Consider the following restrictions for drop-in software updates:

    • Do not require any update to the configuration

    • Cannot cause feature regression

    • Can change default or previously configured behavior only for bug fixes and security issues

    • Can deprecate but not remove existing functionality

  • Major upgrade:

    Usually, an upgrade from a version of Java Agent to a newer major version, as defined in Release naming. For example, upgrade from 5.10 to 2023.3 is a major upgrade.

    Major upgrades can introduce additional functionality and fix bugs or security issues. Major upgrades do not have the restrictions of drop-in software update. Consider the following features of major upgrades:

    • Can require code or configuration changes

    • Can cause feature regression

    • Can change default or previously configured behavior

    • Can deprecate and remove existing functionality

Drop-in software update

The examples in this section assume that the agent is installed in /path/to/java_agents/agent_type, and the update is from the minor version 2023.3 to the minor version 2023.6.

Tomcat Java Agent software update

  1. Read the release notes for information about changes in Java Agent.

  2. Download the agent binaries from the ForgeRock BackStage download site and extract them to a temporary directory.

    The example in this section is extracted to /tmp, and the .jar files are in /tmp/tomcat_agent/lib.

  3. Back up the directories for the agent installation and the web application container configuration:

  4. Redirect client traffic away from protected web applications.

  5. Stop the web applications where the agent is installed.

  6. Locate the following files in the container:

    • agent.jar

    • jee-agents-sdk-version.jar

    The following example finds ./lib/jee-agents-sdk-2023.6.jar:

    • Unix

    • Windows

    $ cd /opt/container
$ find . -type f -name 'jee-agents-*.jar' -print
./lib/jee-agents-sdk-2023.6.jar
    C:\> cd C:\opt\container
C:\opt\container> dir /s jee-agents-*.jar

...
  Directory of C:\opt\container\lib

  date  time          ... jee-agents-sdk-2023.6.jar
...

  7. If agent.jar is present in the container, delete it.

  8. Replace jee-agents-sdk-version.jar with the newer downloaded version. The following example replaces jee-agents-sdk-2023.6.jar:

    • Unix

    • Windows

    $ cd /opt/container
$ rm -f lib/jee-agents-sdk-2023.6.jar
$ cp /tmp/tomcat_agent/lib/jee-agents-sdk-2023.9.jar lib
    C:\opt\container> del lib\jee-agents-sdk-2023.6.jar
C:\opt\container> copy C:\tmp\tomcat_agent\lib\jee-agents-sdk-2023.9.jar lib

  9. (Optional) Update the .jar files outside the container.

    1. Using the .amAgentLocator file, find the directory in which the agent was originally installed:

      • Unix

      • Windows

      $ cd /opt/container
$ cat .amAgentLocator; echo

/path/to/java_agents/tomcat_agent
      C:\opt\container> type .amAgentLocator

C:/path/to/java_agents/tomcat_agent

    2. View the content of the lib subdirectory:

      • Unix

      • Windows

      $ cd /path/to/java_agents/tomcat_agent/lib
$ ls -F

agent.jar
jee-agents-installtools-2023.6.jar
jee-agents-sdk-2023.6.jar
      C:\opt\container> cd C:\path\to\java_agents\tomcat_agent\lib
C:\path\to\java_agents\tomcat_agent\lib> dir

Directory of C:\path\to\java_agents\tomcat_agent\lib
... agent.jar
... jee-agents-installtools-2023.6.jar
... jee-agents-sdk-2023.6.jar

    3. Replace the files with the newer downloaded version:

      • Unix

      • Windows

      $ rm -f * 
$ cp /tmp/java_agents/tomcat_agent/lib/*.jar .
$ ls -F

agent.jar
jee-agents-installtools-2023.9.jar
jee-agents-sdk-2023.9.jar
      C:\path\to\java_agents\tomcat_agent\lib> del *.jar 
C:\path\to\java_agents\tomcat_agent\lib> copy C:\temp\java_agents\tomcat_agent\lib\*.jar .

C:\tmp\tomcat_agent\lib\agent.jar
C:\tmp\tomcat_agent\lib\jee-agents-installtools-2023.9.jar
C:\tmp\tomcat_agent\lib\jee-agents-sdk-2023.9.jar

  10. Replace the current agentadmin file with the newer downloaded version:

    • Unix

    • Windows

    $ cd /path/to/java_agents/tomcat_agent/bin 
$ rm agentadmin
$ cp /tmp/tomcat_agent/bin/agentadmin . 
    C:\> cd C:\path\to\java_agents\tomcat_agent\bin
C:\path\to\java_agents\tomcat_agent\bin> del agentadmin agentadmin.bat

C:\path\to\java_agents\tomcat_agent\bin> copy C:\tmp\tomcat_agent\bin\agentadmin.bat .

  11. Start the web applications where the agent is installed.

  12. Check that the agent is performing as expected:

    1. Check the correct version of the agent is running:

      • Set the log level to trace, as described in Logging.

      • In /path/to/java_agents/agent_type/Agent_n/logs/debug, search for lines containing the string X-ForgeRock-Edge-Metadata. The version number is given in the header.

        For example, the log file can contain the following header: --header "X-ForgeRock-Edge-Metadata: JPA 2023.9.

Roll back from a drop-in software update

Before you roll back to a previous version of Java Agent, consider whether any change to the configuration during or since upgrade could be incompatible with the previous version.

Major upgrade

Perform a major upgrade

  1. Read the release notes for information about changes in Java Agent.

  2. Plan for server downtime.

    Plan to route client applications to another server until the process is complete and you have validated the result. Make sure the owners of client applications are aware of the change, and let them know what to expect.

  3. Download the agent binaries from the ForgeRock BackStage download site.

  4. Back up the directories for the agent installation and the web application container configuration:

  5. Redirect client traffic away from protected web applications.

  6. Stop the web applications where the agent is installed.

  7. Remove the old Java Agent, as described in Remove Java Agent.

  8. Install the new agent.

    The installer creates new versions of the following files, with configuration that is relevant to the new version of the agent:

  9. Using the agent’s release notes and AM’s release notes, check for changes and update the configuration.

    To prevent errors, do not copy configuration files from the previous installation to the new installation. Use the new version of the files and update then as necessary.

    • In local configuration mode, update AgentConfiguration.properties manually to include properties for your environment, using backed-up files for guidance.

      The AgentBootstrap.properties file created by the installer contains bootstrap properties relevant to the new version of the agent.

    • In remote configuration mode, change the agent configuration using the AM admin UI.

  10. Secure communication between AM and the agent with appropriate keys. For information, refer to Configure AM servers to communicate with Java Agents.

  11. Start the web applications where the agent is installed.

  12. Check that the agent is performing as expected:

    1. Check the correct version of the agent is running:

      • Set the log level to trace, as described in Logging.

      • In /path/to/java_agents/agent_type/Agent_n/logs/debug, search for lines containing the string X-ForgeRock-Edge-Metadata. The version number is given in the header.

        For example, the log file can contain the following header: --header "X-ForgeRock-Edge-Metadata: JPA 2023.9.

  13. Allow client traffic to flow to the protected web applications.

Roll back from a major upgrade

Before you roll back to a previous version of Java Agent, consider whether any change to the configuration during or since upgrade could be incompatible with the previous version.

Post update and upgrade tasks

After upgrade or update, review the what’s new section in the release notes and consider activating new features and functionality.

For information about other post-installation options, refer to Post-installation tasks.
