Installing the JS7 Agent

Prerequisites

Preparation

  • Choose the Agent archive for the target system from the JS7 - Download page.
  • For Windows systems a .zip archive including the installer is available.

Installation

  • Extract the downloaded archive js7_agent_windows_installer.<release>.zip to a directory, e.g. C:\Temp.

  • The installer can be run with the GUI or in headless mode, see JS7 - Agent - Use of Unix/Windows Headless Installation.

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

  • Run the installer for the JS7 Agent using

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




  • Click Next on the welcome window.



  • The Licenses are displayed with step 2 of the installation.  It shows the types of licenses available for the agent.



  • The installer opens a GUI to specify the installation path after you accept the terms of the License Agreement.



  • Add the HTTP port that is used by the JS7 Agent. Make sure that the HTTP port is available, i.e. is not otherwise used. If you run other applications that use this port then choose a different port.
  • If you specify a service account then make sure that this account has "Log on as service permissions".



  • Select the Configuration path for the Agent where you want to store the journals (state folder) for the agent and the keystore and truststore for the agent.


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


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



  • The Processing panel displays the progress of the second part of the installation procedure.


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

  • 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.

Updating the JS7 Agent

The 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 the JS7 Agent instance.
  • Prepare to rollback in case that the update of the JS7 Agent is not successful:
    • Take a backup of the Agent's installation directory and configuration directory, e.g. by creating a .zip archive.
      • Installation Directory:
        • The default installation path for the Agent is C:\Program Files\sos-berlin.com\js7\agent
      • Configuration Directory
        • The default configuration path for the Agent is C:\ProgramData\sos-berlin.com\js7\<agent_port>

Update

The update using the GUI can be done by rerunning the installer setup.cmd file from the .zip archive and by providing the same parameters such as installation paths, ports etc.

Rollback

To perform the rollback on Windows follow the below steps:

  • To perform JS7 Agent instance rollback run the uninstaller.
    • 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 .tar.gz/.zip archive for the installation directory and configuration directory to the respective location.
  • Re-install the Windows Service from the command line:
    • Switch to the .\bin directory for the Agent from the command line
      • The default location of the .\bin directory is:

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

    • Run the below command that installs the Agent's Windows Service. 

      agent.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 by the environment variable JS7_AGENT_LOGS or in the logs sub-directory of the Agent configuration directory.

  • The default path of the logs directory for the Agent are:
  • 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.
