Verastream Host Integrator (VHI) version 7.7 SP2 Update 2 released November 2019. These release notes list the features and known issues in this release and additional product information. VHI integration encapsulates host functionality into services for
rapid re-use in new applications.
What's New
Beginning with the 7.7 SP2 release, VHI contains Azul Zulu OpenJDK 1.8. Updating to this version of OpenJDK helps address security vulnerabilities, along with providing additional benefits. To debug Java source code, you need to download the
src.zip
file provided by Azul OpenJDK.
To download the Open JDK package installed with VHI:
- Navigate to https://www.azul.com/downloads.
- Select the correct Java 8 version in zip format. Download.
- After the download completes, the
src.zip
file is located in the root directory of the zip file.
- Copy it to
Verastream\java\jdk-ver
.
This version of VHI provides increased usability enhancements as well as addressing security vulnerabilities. Enhancements and fixes which shipped in previous releases are included in this release. All releases are cumulative.
What's New for 7.7 SP2 U2
- New functionality has been added to the Import Model Elements dialog box. You now have the ability to filter and sort entities, tables, and variables using regular expressions to streamline importing model elements.
- See the help topic, Import Model Elements, under Creating a Model in the Design Tool documentation.
- VHI now ships version 1.8.0_232 of the Java Development Kit (JDK).
- VHI has been upgraded to use the libncurses.so.6 shared library and no longer requires libncurses5.so.
- The Event Handler API documentation has been updated and now includes the NOT operator for WaitForMultipleEvents.
- See the help topic, Event Handling API, under Connectors and APIs in the Design Tool documentation.
- WaitForMultipleEvents now includes a THEN operator to allow for sequential event processing.
- There have been multiple small enhancements to the Design Tool Procedure Editor:
- When hovering over a field in the Procedure Editor, the location of the field within the procedure is displayed. This feature was disabled in a previous release and has been restored.
- You are now warned before you can delete an entity.
- The command list for an operation is now visible when selecting the path between entities.
See the help topic, Creating Procedures Using the Procedure Editor, under Creating Tables and Procedures in the Design Tool documentation.
- The validity of a model is now verified before using packagemodel.bat or activatemodel.bat deployment scripts.
- The Entity drop-down list updates immediately after an enitity is deleted.
- Concurrent sessions are reset each day which results in accurate email notifications.
- The Java demo directory and src.zip have been removed.
Known Issues
- 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.
Resolved Issues
- In previous versions, in the Host Event Edit dialog box, when switching focus between a WaitForDisplayString event and another event in the Events panel, existing backslash characters in the String value of the Event parameters of the WaitForDisplayString
operation were duplicated. This is no longer the case.
- The issue of high CPU usage during a client session disconnect while the Administrative Console is monitoring the session has been addressed. This no longer occurs.
- In the Design Tool, the Entity drop-down list no longer displays the previous entity after the screen has been updated.
- Previously, the Administrative Console did not display correct signing information. This has been corrected.
- An issue with the zLinux install program was fixed. The installer no longer uses a hard-coded path to the Java SDK.
- When upgrading the Administrative Console from an evaluation copy to a production license, an inaccurate label was previously displayed and required restarting the session server. This is no longer the case.
