Introduction

  • First of all, you don't need to read all the parts of this article. For most situations it is sufficient to check the prerequisites, download the software and run the installer that will guide you.
  • In this article you will find the details about available installer options, updates and rollbacks for interested parties.
  • The JS7 Agent can be installed and operated on any Unix and Windows environments that meet the prerequisites.
  • The JS7 Agent can be installed on Windows using the graphical installer - for headless installation see JS7 - Agent - Use of Linux/Windows Headless Installation.

Prerequisites

  • A Java Runtime Environment 1.8 or newer is required. For details see the  Which Java versions is JobScheduler available for? article.
  • It is recommended that a time service is operated on the server that hosts the Agent in order to synchronize the system clock's time.

Download

  • Select the Agent archive for Windows systems and the graphical installer from the JS7 - Download page.
  • A .zip archive including the installer is available for Windows systems: js7_agent_windows_installer.<release>.zip.

Installation Video

This video explains how to install the JS7 Agent:

Installing the JS7 Agent

Installation

Extract the downloaded archive to a directory, e.g. C:\Temp.

After extraction of the installer .zip archive the directory structure will include:

  • agent_install.xml (installer response file)
  • install_agent.txt (installation notes)
  • js7_agent_windows.<release>.jar (installer library for a given release)
  • license.gpl (copy of  GPLv3 (General Public License) )
  • license.txt, license.html (copy of JS7 JobScheduler Commercial License)
  • setup.cmd (installer script)

Note the following implications before running the installer:

  • The installer can be run in graphical or in headless mode, see the JS7 - Agent - Headless Installation on Unix and Windows article.

  • The installer asks for elevated administrative privileges, so it will not be necessary to change the permissions in the .\service directory and the installer will set read/write permissions for the .\logs directory.
  • After the installation you will find:
    • a Windows Service "SOS JS7 Agent -port=<http-port>"
    • an executable file .\service\js7_agent_<http-port>.exe that is started by the Windows Service.

Run Installer

  • Run the installer for the JS7 Agent using the following command:

    Windows command to run the installer GUI
    C:\Temp\agent.<release>\setup.cmd
  • The installer asks for administrative privileges.  
  • Select the language to be used for the setup: English, Japanese and German are available.

Welcome Window

  • Click Next on the welcome window.

License Options

  • The License window displays the licenses available for the JS7 Agent.
    • The Open Source License GPLv3 (General Public License) is available.
    • The SOS Commercial License can also be selected. When using this license, the license certificate file that you receive from SOS after purchase of a license will be added when installing the Controller that forwards the license to the Agent. For details see the JS7 - How to apply a JS7 License Key article.



License Agreement

  • The License Agreement corresponding to the license option selected has to be accepted before installation can occur.

Installation Directory

  • The installer opens a window to specify the installation directory after you have accepted the terms of the License Agreement.

Installation Settings

  • Add the HTTP port that is to be used by the JS7 Agent. Make sure that the HTTP port is available and is not otherwise used. If you run other applications that use this port then choose a different port.
  • If you specify a Windows Service account, make sure that this account has "Log on as service permissions". Note that the credentials that you enter in this window are stored in clear text with the installer response file. It is considered more secure not to add credentials with this step, but to add credentials directly with the Windows Service panel after installation.

Data Directory for Configuration, Logs, Journals

  • Choose the data directory for the Agent which you want to use to store the Agent's configuration, log and journal files.

Specific Directories

  • If you choose the installation directory to be located in C:\Program Files then it is recommended that you specify a log directory outside of the installation path, e.g. C:\ProgramData\sos-berlin.com\js7\agent_<http-port>\logs.
  • The installer sets read/write permissions for the specified Windows Service account. Typically only the administrator group should have write permissions for C:\Program Files.



Installation Progress

  • This step displays progress of the first part of the installation procedure.
  • Changes to installer options can no longer be applied once this step has been started.

Configuration Progress

  • The processing panel displays progress of the second part of the installation procedure that includes setting permissions and installing the Windows Service.



    • The information displayed with this step will be written to the installation log file which can be found in the JS7_AGENT_DATA/logs folder.

Completion

  • The last step of the installation displays a summary of the installation (success/error) and paths to relevant information.



    • Note that if a problem occurs during installation a warning will be displayed and a link to the installation log file will be provided.

    • A failed installation can be repeated at any time, Uninstalling is not required.

    • C:\Program Files\sos-berlin.com\js7\agent (installation directory)

Updating the JS7 Agent

Find detailed instructions in the JS7 - Update and Patch Management article.

An update of the JS7 Agent is performed from the same download archive as used for any fresh installation:

  • js7_agent_windows_installer.<release>.zip

Preparation

  • Stop any running JS7 Agent instances. Note that more than one Agent instance can be launched from a single Agent installation.
  • Prepare to rollback in case the update of the JS7 Agent is not successful:
    • Make a backup of the Agent's installation directory and data directory, e.g. by creating a .zip archive.
      • Installation Directory:
        • The default installation directory for the Agent is C:\Program Files\sos-berlin.com\js7\agent
      • Data Directory
        • The default data directory for the Agent is C:\ProgramData\sos-berlin.com\js7\agent_<http-port>

Update and Upgrade

An update/upgrade using the graphical installer can be carried out by rerunning the installer setup.cmd file from the .zip archive and by providing the same parameters such as installation paths, ports etc.

Rollback

Follow the steps listed to perform a rollback on Windows:

  • Run the uninstaller to perform JS7 Agent instance rollback.
    • The default location of the uninstall.cmd file is:
      • C:\Program Files\sos-berlin.com\js7\agent\Uninstaller
  • Restore the folders from the backup by unzipping the .zip archive for the installation and configuration directories to their respective locations.
  • Re-install the Windows Service from the command line:
    • Switch to the  Agent's .\bin directory from the command line
      • The default location of the .\bin directory is:

        • C:\Program Files\sos-berlin.com\js7\agent\bin

    • Run the following command that installs the Agent's Windows Service:

      agent.cmd install-service

Installation Log

The installer creates a log file in the directory which is specified in the JS7_AGENT_LOGS environment variable or in the logs sub-directory of the Agent's data directory.

  • The default path of the logs directory for the Agent is:
    • C:\ProgramData\sos-berlin.com\js7\agent_<http-port> for Windows.
  • Installation log files use names according to the pattern Install_V<release>_<date-time>_....log where <release> is the release number and <date-time> refers to the point in time of installation.
  • For further information about logging see the JS7 - Logging article.

Automated Start-up and Shutdown

It is recommended that on Windows systems the Agent is operated as a Windows Service as such services can be configured to start/stop automatically on server start-up and shutdown.

  • Consider assigning a service account to the JS7 Agent service with the Windows Service Panel.
  • Consider allowing the JS7 Agent service to be automatically started on server start-up.

Initial Operation

Having completed the installation or update of a JS7 Agent you can either start the Agent manually or from its Unix daemon/Windows Service - see the JS7 - Agent Command Line Operation article for details.
