Preparing to apply feature packs or fix packs on the Presentation Server


Before applying feature packs or fix packs on the Presentation Server, ensure that you review and complete the following prerequisite activities and requirements.

  • Before you apply the fix pack, ensure that version 11.3.01 of the Presentation Server is up and running and you are able to log on to the Presentation Server.

  • As a best practice and to avoid a file lock happening during the upgrade process, exclude the installation directory from the on-access virus scanner. For more information, see Disable on-access virus scanners.

  • Ensure to close all the files and folders opened in the current session as well as close other user sessions on the server before applying feature packs or fix packs.
  • Ensure that the environment variable TRUESIGHTPSERVER_HOME is set to the Presentation Server installation folder.
  • (Linux) Ensure that the limits for open files and processes mentioned in the /etc/security/limits.conf and /etc/security/limits.d files are same or the limits in the /etc/security/limits.d file is blank or removed. If the limits are different in these two files, you may get an installation error.
  • (Linux) To be able to perform the installation, a non-root user needs the Execute permission for the /Linux/Disk1 folder.

  • Ensure that the Presentation Server is running before applying feature packs or fix packs. If the Presentation Server is not running, start it by running the following command:(Windows) tssh server start(Linux) ./tssh server start

    Note

    Run the tssh server status command from the installationDirectory\truesightpserver\bin folder and verify that the status of the Presentation Server is Running before applying feature packs or fix packs.

  • If you are operating in the high availability mode, before applying feature packs or fix packs, ensure that the primary Presentation Server is active. Run the tssh ha status to check the high-availability deployment status and verify whether the primary server is up and running.
  • Manually stop any components that are directly connected to the Presentation Server (for example, Infrastructure Management, App Visibility Manager components). 

  • If you have custom security certificates for the internal communication between the Presentation Server and App Visibility Manager, your files might be overwritten by the upgrade process. To prevent this, see instructions "To replace security files on the Presentation Server for communication with the App Visibility portal" in the Applying private certificates between the App Visibility portal and the Presentation Server topic.
