• The Controller can be installed on Linux systems without use of an installer by extracting a .tar.gz archive.
  • The Controller can be installed on Windows systems:
    • without use of an installer by extracting a .zip archive. This allows a portable installation which requires no administrative privileges.
    • by running the Controller installer in headless mode or
    • by running the graphical installer see JS7 - Controller - Using the Windows Graphical Installer.


  • A Java Runtime Environment starting from version 1.8 is required. For details see the Which Java versions is JobScheduler available for? article.
  • It is necessary that a time service is operated on the server which hosts the Controller. This is to synchronize the system clock's time.
  • Technically the Controller can be operated in any Unix environment. However, support for operation of the Controller is focused on Linux systems as described in the JS7 - Platforms article.


  • Download the Controller archive for the target system from the JS7 - Download page.
    • For Unix systems:
      • A .tar.gz archive is available that is extracted to create the Controller's directory structure (see below).
        • js7_controller_unix.<release>.tar.gz
    • For Windows systems:
      • A .zip archive is available which will create the Controller's directory structure when it is extracted (see below).
        • js7_controller_windows.<release>.zip
      • A .zip archive including the installer is available which can be used to run the installer in headless mode.
        • js7_controller_windows_installer.<release>.zip

      • This step is not required if you extract the Controller e.g. to C:\ProgamData.
      • Start a command prompt with elevated administrative rights and execute, for example:

        Allow full acces for "Users" on .\service and .\logs directories
        cd "path\to\installation-directory"
        icacls "service" /L /grant *S-1-5-32-545:(OI)(CI)F
        icacls "logs" /L /grant *S-1-5-32-545:(OI)(CI)F
  • To start the Controller you can use the commands described in the JS7 - Controller - Command Line Operation article or your can automate startup using the instructions provided by the "Automated Startup and Shutdown" section below.

Customers with a commercial license wishing to cluster the JS7 Controller for high availability have to add the license key during initial operation, see the JS7 - Initial Operation for Controller Cluster article for more information.

Update and Upgrade

Detailed instructions for updating and upgrading can be found in the JS7 - Update and Patch Management article.


  • Stop the JS7 Controller instance.
  • Prepare to rollback in case the update of the JS7 Controller is not successful:
    • Make a backup of the Controller's installation and data directories by, for example, creating a .tar.gz/.zip archive.
      • Installation Directory:
        • The default installation directory for the Controller is:
          • /opt/<controller-id> for Unix systems,

          • C:\Program Files\\js7\controller\<controller-idfor Windows systems.
      • Data Directory
        • The default data directory for the Controller is:
          • /home/sos/<controller-id> for Unix systems,
          • C:\ProgramData\\js7\controller\<controller-idfor Windows systems.

Running the Update

The update of the JS7 Controller is performed from the same download archive as is used for any fresh installation.

  • When extracting files to a location that has already been used then existing files with the same name will be overwritten. Files added by the user will remain in place.
    • This is particularly true for the ./bin/|cmd Controller Start Script which should not be modified by users.
  • The .tar.gz/.zip archive includes Java libraries in the ./lib directory. This ships with file names that are unique to every Controller release.
    • Therefore, before extracting files, rename or remove an existing ./lib directory in order to store libraries from the current Controller release only in this directory.

Example for Installation from the Unix Command Line

The Controller is installed with a few straightforward commands:

Example how to install from the Unix command line
# download archive (consider to use a current release)
curl  '' --output js7_controller_unix.2.1.1.tar.gz

# extract archive
tar xvzf js7_controller_unix.2.1.1.tar.gz

# find extracted files in the "controller" sub-directory
ls -la controller

# prepare an instance start script from the example
cd controller/bin
cp -p

# optionally activate/adjust environment variables in

# run the Controller
./ start

# find log output
tail -100 ../var/logs/controller.log

Installation by Windows Installer in Headless Mode

The Controller installer is available for Windows systems only. 


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

  • controller_install.xml (installer response file)
  • install_controller.txt (installation notes)
  • js7_controller_windows.<release>.jar (installer library for a given release)
  • license.txt, license.html (copy of JS7 JobScheduler Commercial License Agreement)
  • setup.cmd (installer script)

Installer Response File

  • The Controller installation uses the controller_install.xml response file, which includes parameters such as the installation path, ports, etc.
    • For a fresh installation the installer response file is included with the downloaded archive.
    • The default location of the controller_install.xml file from a previous installation is:
      • C:\Program Files\\js7\controller\<controller-id>
    • The <controller-id> is a unique identifier for a Controller which you specify from the installer response file:
      • You are free to choose an identifier, e.g. controller-test, controller-prod if you intend to run a separate Controller for each environment. Upper case and lower case characters are observed, the characters a-z, A-Z, 0-9, underscore and hyphen are allowed. Spaces are not allowed in a Controller ID.
      • If you intend to operate a Controller cluster then both Controller instances have to use the same Controller ID.
  • Customers with a commercial license should choose the relevant license option and specify the location of the license key with the installer response file.
  • The controller_install.xml file is explained in the code listing below. The comments included are intended to be self-explanatory.

Running the Installer

  • Running the installer for the JS7 Controller on Windows systems:

    Running the installer of JS7 Controller on Windows systems
    C:\temp\controller.[release]> setup.cmd controller_install.xml

Directory Structure

After installation the resulting directory structure will be similar to that described in the Installation from .tar.gz/.zip Archive section above.

Directories for installation and configuration of the Controller might differ.



  • Stop the JS7 Controller instance.
  • Prepare to rollback if the update of the JS7 Controller is not successful.
    • Make a backup of the Controller's installation and configuration directories by, for example, creating a .zip archive.
      • Installation Directory:
        • The default installation directory for the Controller instance is:
          • C:\Program Files\\js7\controller\<controller-id>
      • Configuration Directory
        • The default configuration directory for the Controller instance is:
          • C:\ProgramData\\js7\controller\<controller-id>

Running the Update

The update procedure makes use of the same installer response file as described for a fresh installation.

Steps to run the installer are the same as described for a fresh installation.

Installation Log

The installer creates a log file in the directory specified in the JS7_CONTROLLER_LOGS environment variable or in the logs sub-folder of the Controller configuration directory.

  • The default location of the logs directory for the Controller is:
    • C:\ProgramData\\js7\controller\<controller-id>
  • Installation log files are named 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.


Rollback Installation from .tar.gz/.zip Archive

  • To rollback the installation of a JS7 Controller instance, remove the newly created installation and configuration directories of the JS7 Controller.
  • Restore the directories from a previous backup, e.g. by extracting the relevant .tar.gz/.zip backup archives to the installation and configuration directories.

Rollback Installation by Windows Installer in Headless Mode

  • To perform the rollback of the JS7 Controller instance run the uninstaller from the command line.
    • The default location of the uninstall.cmd file is:
      • C:\Program Files\\js7\controller\<controller-id>\Uninstaller
  • Restore from a previous backup by, for example, extracting the .tar.gz/.zip archive to the installation directory and configuration directory.
  • Re-install the Windows Service from the command line:
    • Switch to the .\bin directory for the Controller from the command line.
      • The default location of the .\bin directory is:
        • C:\Program Files\\js7\controller\<controller-id>\bin

    • Run the following command to install the Controller's Windows Service. 

      controller.cmd install-service

Automated Startup and Shutdown

For Unix systems startup and shutdown configurations apply that are executed by the root account from, for example, /etc/init.d scripts and by use of systemd.

For Windows systems operation of the Controller by a Windows Service is recommended as such services can be configured to start/stop automatically on server startup and shutdown.

  • Consider assigning a service account to the JS7 Controller service with the Windows Service Panel.
  • Consider allowing the JS7 Controller service to be automatically started on server startup.
