Install - Java Windows Dynamic Agent on Tomcat App Server

Tomcat Compatibility

vFunction supports Apache Tomcat version 6 and later.

Installation Wizard

To help with the installation process, vFunction offers an Installation Wizard. This Wizard provides additional information about the Prerequisites as well as steps for deploying the vFunction Agent to your environment.

Please contact support@vfunction.com or your vFunction Contact(s) for the password to start using this Wizard.

Installation Steps

  1. Ensure Prerequisites are met
  2. Download the vFunction Windows Controller Installation ZIP
  3. RDP to the Windows Server as the user who runs the Application / Application Server
  4. Move the Installation ZIP to the location on the Windows Server where vFunction should run
  5. Extract the vFunction Installation Package
  6. Retrieve the vFunction UI’s Application UUIDs:
  1. Log into the vFunction Server’s UI in a browser
  2. In the top-left corner, click the dropdown and select the relevant Application
  3. In the top-center menu bar, click the “Learning” tab
  4. On the left-side, click the “Select Controllers” link
  5. On the left-side, click the “Install Controller” link
  6. In the dialog box, find the YAML-formatted text box that contains the following details. You’ll need these details at a later stage below:
controller:
  name: {display name for this controller}
  host: $your_VF_Server_address
  org_id: 93af7f38-0000-0000-0000-bd9516798497
  app_id: 9fb228fc-0000-0000-0000-db8e83427e14
  client_id: caeadcd1-0000-0000-0000-9c9b37a9e119
  client_secret: 68cb85eb-0000-0000-0000-fb9e7f1d9240
  1. Optional: In PowerShell, add Environment Variables for the vFunction Dynamic Agent
# See description in https://kb.vfunction.com/installations/configurable-settings/mono-dynamic-agent/java/windows
[System.Environment]::SetEnvironmentVariable('VF_CONTROLLER_DEFAULT_JAVA_CONTROLLER_NAME','CHANGE_ME')
[System.Environment]::SetEnvironmentVariable('VF_CONTROLLER_DEFAULT_JAVA_CONTROLLER_HOST','CHANGE_ME')
[System.Environment]::SetEnvironmentVariable('VF_CONTROLLER_DEFAULT_JAVA_CONTROLLER_ORG_ID','CHANGE_ME')
[System.Environment]::SetEnvironmentVariable('VF_CONTROLLER_DEFAULT_JAVA_CONTROLLER_APP_ID','CHANGE_ME')
[System.Environment]::SetEnvironmentVariable('VF_CONTROLLER_DEFAULT_JAVA_CONTROLLER_CLIENT_ID','CHANGE_ME')
[System.Environment]::SetEnvironmentVariable('VF_CONTROLLER_DEFAULT_JAVA_CONTROLLER_CLIENT_SECRET','CHANGE_ME')
[System.Environment]::SetEnvironmentVariable('VF_CONTROLLER_DEFAULT_JAVA_AGENT_APPLICATION_SERVER','CHANGE_ME')
[System.Environment]::SetEnvironmentVariable('VF_CONTROLLER_DEFAULT_JAVA_AGENT_APPLICATION_JAVA_VERSION','CHANGE_ME')
  1. Optional: Alternatively to Step #7, open the BASE_DIR\vfunction\config\installation\instances\default-java\installation.yaml to set the same values instead of using Environment Variables
# See description in https://kb.vfunction.com/installations/configurable-settings/mono-dynamic-agent/java/windows

  1. In PowerShell, unblock the files in the installation directory
### Replace the BASE_DIR with the actual value with the actual value where vFunction was extracted, such as C:\vfunction
dir -Path "BASE_DIR" -Recurse | Unblock-File
  1. In Powershell, run the installation script
### Replace the BASE_DIR with the actual value with the actual value where vFunction was extracted, such as C:\vfunction
powershell -NoProfile -ExecutionPolicy unrestricted -Command "BASE_DIR\vfunction\controller-installation\install.ps1 -instance default-java"
  1. In a text editor, open the vFunction Startup Parameters Example file
### Replace the BASE_DIR with the actual value with the actual value where vFunction was extracted, such as C:\vfunction
BASE_DIR\config\agent\instances\default-java\vmargs-examples\tomcat
  1. Launch the tomcatw.exe to set the Tomcat JAVA_OPTS
  2. Open the Java tab of the dialog box
  3. Copy the vFunction Startup Parameters from the text editor with one parameter per line into the Options text box
### Replace BASE_DIR with the actual value
### In some circumstances, you may need to add a second Backslash to each folder in the filepath for the path to be recognized properly. If you see an error about being unable to find the JVMTIAgent.dll, this is probably the case
-agentpath:BASE_DIR\agent\JVMTIAgent.dll=conf=BASE_DIR\config\agent\instances\default-java\native-conf.json
-javaagent:BASE_DIR\agent\runtime-agent.jar=ConfigLocation=REPLACE_BASE_DIR\config\agent\instances\default-java\vfunction-runtime-override.properties
-Dcom.vfunction.logging.logFile=BASE_DIR\log\instances\default-java\vfagent.log
  1. Restart the Tomcat instance
  2. Confirm that the Application comes up and functions as expected
  3. If any issues arise:
