Installing the JS7 Controller

Prerequisites

Introduction

  • First of all, you don't need to read this article in all its parts. 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 find the details about available installer options, updates and rollback for interested parties.
  • The Controller can be installed by use of the graphical installer, for headless installation see JS7 - Controller - Headless Installation on Linux and Windows.

Prerequisites

Preparation

  • 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. Note, however, that the JS7 - Platforms article describes support for Controller operation in more detail.

Download

  • Select Choose the Controller archive for the target system Windows systems and the graphical installer from the JobScheduler JS7 - Download page.
  • For On Windows systems a .zip archive including the installer is available .

Installation

  • Extract the downloaded archive from js7_controller_windows_installer.x.x.x.zip to an arbitrary <release>.zip.

Installing the JS7 Controller

Installation

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

After extraction of the installer .zip archive the directory structure includes:

  • controller_install.xml (installer response file)
  • install_controller.txt (installation notes)
  • js7_controller_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 Agreement)
  • setup.cmd (installer script)

Consider the following implications before running the installer:

  • The installer can be run with or without a GUIin graphical mode or in headless mode, see JS7 - Controller - Headless Installation on Linux and Windows.

  • The installer asks for elevated administrator administrative privileges, therefore it is not necessary required to change the permissions in the .\service directory and the installer sets read/write permissions for the log .\logs directory.
  • After the installation you will find
    • a Windows service Service "SOS JS7 Controller -id=<Controller ID><controller-id>"
    • an executable file .\service\js7_controller_<Controller ID><controller-id>.exe that is started by the Windows Service.

Run Installer

  • Run the installer dialog for the JS7 Controller using the following script:

    Code Block
    languagebash
    titleWindows command to open run the graphical installer GUI
    > C:\Temp\controller.x.x.x<release>\setup.cmd
  • The installer asks for elevated administrator permissionsadministrative privileges.  
  • Select the language to be used for the setup: English, Japanese and German are available.

Installation Settings

  • In the next window the Controller ID, which is a unique identifier for a Controller, is specified. You can use identifiers such as "controller-test", "controller-production" etc. Character case is significant, 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 with two Controller instances for the active and standby cluster members, then specify the same identifier during installation of each Controller instance as otherwise the instances will not be considered members of the same cluster. This identifier cannot be modified after installation, changes to the Controller ID require reinstallation of the Controller.
    • A checkbox allows the initial role of the current Controller instance to be specified - i.e. whether it starts with an active or a standby role. Do not select this checkbox if you are operating a standalone Controller instance.
    • Note that operation of a Controller cluster requires a license certificate to have been specified in the License Agreement step described above. See also JS7 - License.
  • Add the HTTP port that is to Add the HTTP port which can be used by the JS7 Controller. Make sure that the HTTP port is available , i.e. and is not otherwise used. If you run other applications that use this port then choose a different port.
  • If you specify a service Windows Service account then make sure that this account has "Log on as service permissions". Consider that credentials that you enter to 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 after installation using the Windows Service panel.

Specific Directories

  • If you selected choose the installation path directory to be located in C:\Program Files then it is recommended to choose configure the log directory to be outside of the installation path, e.g. C:\ProgramData\sos-berlin.com\js7\controller\logs.
  • The installer sets read/write permissions for the specified Windows service user but normally exclusively Service account. Typically only the administrator group should have write permissions for C:\Program Files.

Installation Progress

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

Configuration Progress

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



    • The information displayed with this step is written to the installation log file , which is to that can be found in the JS7_CONTROLLER_DATA/logs folder.

Completion

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

...

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

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

Rollback

To perform a rollback on Windows systems follow the below steps:

  • Run the JS7 Controller uninstaller.
    • The default location of the uninstall.cmd file is:
      • C:\Program Files\sos-berlin.com\js7\controller\<controller-id>\Uninstaller

Updating the JS7 Controller

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

  • js7_controller_windows_installer.x.x.x.zip for Windows<release>.zip

Preparation

  • Stop the JS7 Controller instance, e.g. using the Controller's Windows Service.
  • Prepare to rollback in case that the update of the JS7 Controller is not successful:
    • Create Take a backup of the Controller's installation and configuration directories, e.g. by creating a .zip archive for the.
      • Installation Directory
        • The default installation path directory for the Controller is C:\Program Files\sos-berlin.com\js7\controller\<controller-ID> on Windows.<controller-id>
      • Configuration Directory
        • The default configuration path directory for the Controller is C:\ProgramData\sos-berlin.com\js7\controller\<controller-ID> on Windows.
  • Take a Backup of the above archives created.

Update

        • <controller-id>

Update

An The update using the GUI graphical installer can be done by rerunning running the installer (setup.cmd) file  file from the .zip archive and by providing the same parameters such as installation pathsdirectory, ports port etc.

Rollback

To perform the a rollback on Windows systems follow the below steps:

  • To perform Run the JS7 Controller instance rollback run the uninstaller.
    • The default location of the uninstall.cmdcmd file is:
      • C:\Program Files\sos-berlin.com\js7\controller\<controller<controller-ID>\Uninstaller on Windows.id>\Uninstaller
  • Restore the Controller folders from the backup by unzipping the .zip archive for the installation directory and configuration directory directories to the their respective locationlocations.
  • Re-Install install the windows service Windows Service from the command line:
    • Switch to the Controller's ./bin directory for the Controller \bin directory from the command line.
      • The default location of the ./\bin directory is:

        • C:\Program Files\sos-berlin.com\js7\controller\<controller<controller-ID>\bin on Windows.id>\bin

    • Run the below command. This command following command that installs the Controller's Windows Service. :

      controller.cmd install-service [-http-port=<number>] [-ip-address=<hostname or ip address>]

Installation Log

The installer creates a log file in the directory that is pointed to indicated by the environment variable JS7_CONTROLLER_LOGS or in the logs subdirectory  sub-directory of the Controller's configuration directory.

  • The default path location of the logs directory for the Controller is:
    • C:\ProgramData\sos-berlin.com\js7\controller/<Controller<controller-ID> id> on Windows.
  • Installation log files are named use names according to the pattern, Install_V[V<release]>_[<date&-time]>_....log where release<release> is the version release number and <date and time refer -time> refers to the point in time of installation.
  • For further information about logging refer to the overview of log files with the JS7 - Logging article.

Automated Startup and Shutdown

For Unix systems startup and shutdown configurations apply that are executed by the root account e.g. from /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 to assign a service account to the JS7 Controller service with the Windows Service Panel.
  • Consider to allow the JS7 Controller service to be automatically started on server startup.
