Installation

Unzip the downloaded archive file to an arbitrary directory.
The resulting directory structure includes (only files and folders immediately relevant):
- bin
  - agent.cmd
    - The start script for Windows platforms.
  - agent.sh
    - The start script for Unix platforms.
  - agent_instance.sh-example
    - A template for configuring multiple instances of the Universal Agent
- lib
  - The directory for Java libraries.
  - Configure the settings in log4j2.xml file if you want to adjust the logger settings.
- var_4445
  - logs
  - config/private (for ssl configuration)
  - tmp (for internal use)
- service (for Windows)

On Windows Systems:

You have to change the directory permissions for the .\logs and .\service directories if you extracted the Agent to e.g. C:\Program Files.

This step is not required if you extracted the Agent to e.g. C:\ProgamData.

Start a command prompt with elevated administrative rights and type e.g.

Code Block

language	bash
title	set full acces for "Users" on .\service and .\logs directory

cd "path\to\Agent installation"
icacls "service" /L /grant *S-1-5-32-545:(OI)(CI)F
icacls "logs" /L /grant *S-1-5-32-545:(OI)(CI)F

If multiple instances are configured then every instance must have its own ./var_4445 data directory (e.g. ./var_<port of the instance>)

...

The update to the JS7 Agent is performed from the same download file archive as we use used for any fresh installation:

...

Stop the JS7 Agent instance.
Prepare a to rollback in case that the updating update of the JS7 Agent is not successful then a backup is necessary.:
- Create a .tar.gz/.zip archive for the:
  - Installation Directory:
    - The default installation paths for the Agent are:
      - /opt/sos-berlin.com/js7js7/agent on Linux systems and
      - C:\Program Files\sos-berlin.com\js7\agent on Windows.
  - Configuration Directory
    - The default configuration paths for the Agent are:
      - /home/sos/sos-berlin.com/js7js7/agent_<port> on Linux systems and
      - C:\ProgramData\sos-berlin.com\js7\agent_<port> on Windows.
Take a Backup of the above archives created.

Note: For the Linux environments taking the backup of the directories and extracting them at the time of rollback is sufficient but , however, in the case of Windows , it is also required to re-install the service of the Agent.

Update

Installer Options

When the Agent was previously installed previously it adds a added the agent_install.xml file that includes parameters such as the installation path, ports, etc.
- The default location of the agent_install.xml file is:
  - /opt/sos-berlin.com/js7js7/agent on Linux systems and
  - C:\Program Files\sos-berlin.com\js7\agent on Windows.

The agent_install.xml the file is shown in file is explained with the code listing below. The extensive comments are intended to be self-explanatory.

Rollback

To perform the a rollback there are different steps to be followed for Windows and Linux.

Rollback JS7 Agent Instance on Windows

To perform the rollback of a JS7 Agent instance rollback run the uninstaller from the command line.
- The default location of the uninstall.cm|sh file is:
  - /opt/sos-berlin.com/js7/agent/Uninstaller on Linux systems and
  - C:\Program Files\sos-berlin.com\js7\agent\Uninstaller on Windows.
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:/opt/sos-berlin.com/js7/agent/bin on Linux systems and
    - C:\Program Files\sos-berlin.com\js7\agent\bin on Windows.
- Run the below command. This command installs the Agent's Windows Service.
  agent.cmd install-service [-http-port=<number>] [-ip-address=<hostname or ip address>]

Rollback JS7 Agent Instance on Linux

To perform JS7 Agent instance rollback on Linux remove the newly created Installation and the configuration directory of the JS7 Agent.
Restore the folders from the backup by unzipping the .tar.gz /.zip archive for the installation directory and configuration directory to the respective location.

...

The installer creates a log file in the directory that is pointed to by the environment variable JS7_AGENT_LOGS or in the logs subdirectory of the Agent configuration directory.

The default path paths of the logs directory for the Agent are:
- /home/sos/sos-berlin.com/js7/agent_<port> on Linux systems and
- C:\ProgramData\sos-berlin.com\js7\agent_<port> on Windows.
Installation log files are named according to the pattern, Install_V[release]_[date&time]_....log where release is the version release number and date and time refer to the installation.

...

For Unix systems, the start-up and shutdown configurations apply that are executed by root, e.g. in /etc/init.d or corresponding locations and by systemd.

Consider the use of the JS7_USER environment variable to run an Agent that is started by root for a different user account.
What about For use of systemd?with systemd find a sample service file from ./bin/agent.service-example file.

For Windows systems, the start-up of the Agent by installing it as a Windows Service is recommended.
