What's New in 7.8

Configuration changes

  • VHI now ships version 1.8.0_242 of the Java Development Kit (JDK).
  • The session server and management server RMI export ports are now fixed to a documented port number by default.
  • Fixed "Token is invalid" errors in the management server that could occur when replacing the management cluster keypair with a CA signed keypair.

Design Tool enhancements

  • A new file format for model projects is now used by default. This provides better team coordination using source control systems.
  • VHI now supports adding a prefix to model debug file names via the connector APIs and web services. This makes it easier to sort model debug files by category. See - About Model and Environment Variables in the documentation.
  • A new option to select or clear all has been added to the Attributes Test dialog box.
  • Vmr.exe now supports html formatted output by using the -h command line option.
  • The Procedure Test dialog box is now non-modal. This means that the dialog will stay open while changes are being made to the model.
  • In previous releases the Initial Design Tool window position preferences were unreliable, they now behave as described in the Settings documentation.
  • Windows 7 has been removed from the list of supported platforms and is no longer supported.

Known Issues

  • The Linux version of Verastream Host Integrator 7.7 SP2 has a dependency on libncurses5. If it is not already installed, you will need to manually install libncurses5, which can be done before or after the install process. Use your Linux distribution's package manager to install libncurses5. For example, on SLES, run sudo zypper install libncurses5 to install the library. On SLES 15 you may need to enable the Legacy Module to successfully install libncurses5.
  • When installing or upgrading VHI, you may encounter this error message: "The Java scripting manager failed to initialize". The likely cause is that the value of the system environment variable, VHI_ROOT, set at install time, was not updated to the correct install folder.

Micro Focus Technical Support is always available to help you with any issues you may encounter in VHI.
