Java Agents 2024.6

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 ${previous.minor.version} to the minor version ${current.minor.version}.

Tomcat Java Agent software update

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

  2. Download the agent binaries from the 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-${previous.minor.version}.jar:

    • Unix

    • Windows

    $ cd /opt/container
$ find . -type f -name 'jee-agents-*.jar' -print
./lib/jee-agents-sdk-${previous.minor.version}.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-${previous.minor.version}.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-${previous.minor.version}.jar:

    • Unix

    • Windows

    $ cd /opt/container
$ rm -f lib/jee-agents-sdk-${previous.minor.version}.jar
$ cp /tmp/tomcat_agent/lib/jee-agents-sdk-${current.minor.version}.jar lib
    C:\opt\container> del lib\jee-agents-sdk-${previous.minor.version}.jar
C:\opt\container> copy C:\tmp\tomcat_agent\lib\jee-agents-sdk-${current.minor.version}.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-${previous.minor.version}.jar
jee-agents-sdk-${previous.minor.version}.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-${previous.minor.version}.jar
... jee-agents-sdk-${previous.minor.version}.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-${current.minor.version}.jar
jee-agents-sdk-${current.minor.version}.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-${current.minor.version}.jar
C:\tmp\tomcat_agent\lib\jee-agents-sdk-${current.minor.version}.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 .
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 Manage logs.

      • 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 ${current.minor.version}.

    2. Navigate to a protected page on the website and confirm whether you can access it according to your configuration.

    3. Check logs files for warnings and errors.

Roll back from a drop-in software update

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