Technical Notes

This technical note describes systems requirements and platforms that are supported by Verastream Host Integrator (VHI).

Verastream Host Integrator Components

Verastream Host Integrator contains the following components:

* Included in Development Kit only (not Server Kit)

The remainder of this technical note is organized into the following sections:

Server Requirements

The following platforms are supported by the Host Integrator runtime server services (Session Server, Administrative WebStation, Session Monitor, AADS, and Host Emulator).

*The SP notation indicates a supported minimum service pack level for the Microsoft Windows operating system.

Host Integrator uses multiple processors (symmetric multi-processing, or SMP) when available. Intel processors that incorporate Hyper-Threading technology can be used with operating systems (such as Microsoft Windows XP and Microsoft Windows 2003 Server) that provide support for it.

Host Integrator 6.5 supports 64-bit operating system environments, such as Intel x86-64 processor architecture (x64), running as a 32-bit application. Chipsets not listed above, such as Intel Itanium IA64, are not supported.

For running Host Integrator version 6.5 server components in virtual machine environment, Attachmate tests and supports VMware (http://www.vmware.com). Other virtualized environments are supported on a "best effort" basis.

Minimum memory, processor speed, and disk space requirements are described in the Installation Guide (available at http://support.attachmate.com/manuals/vhi.html). For best performance, your physical memory should exceed minimum requirements (recommended minimum 1 GB of RAM, and an additional 128 MB of RAM for each 100 concurrent sessions).

Development Kit Requirements

The following platforms are supported by the Design Tool and Web Builder.

*The SP notation indicates a supported minimum service pack level for the Microsoft Windows operating system.

**For information about Windows Vista support, see Technical Note 2152.

Minimum memory and disk space requirements are described in the Installation Guide (available at http://support.attachmate.com/manuals/vhi.html).

Web Browser and Java Requirements

The following web browser and Java requirements apply to the Design Tool, Web Builder, online help, Administrative WebStation, and Host Emulator components.

Note: Your web browser must have the following capabilities enabled: Java applets, JavaScript, cascading style sheets, and pop-ups.

Development Environment Requirements

To develop a client application (or modify an application generated with Web Builder), you need an appropriate development environment, in addition to Client Connector Requirements.

If your J2EE applications will be using the Host Integrator JCA Resource Adapter (in environments using Enterprise Information Systems such as IBM WebSphere or BEA WebLogic), see also http://www.attachmate.com/docs/verastream/vhi/6.5/help/api/appconn_jca_requirements.html.

Client Connector Requirements

Depending on the connector (AppConn) technology used, the client application you develop has the following runtime requirements.

.NET Connector

For your Windows client application to use the VHI .NET Connector, Microsoft .NET Framework must be installed. The following .NET Framework versions are supported by Host Integrator.

Install the .NET Connector option during setup of the Development Kit or Windows Server Kit. (The .NET Connector also installs and relies upon the COM Connector.)

COM Connector

For your Windows (ASP, VB, VBScript, or C++) client application to use the VHI COM Connector, the appconncom.dll (version 6.5) or appconn.dll (version 6.0 or earlier), and xerces-c_1_4.dll files must be installed and registered. Choose the AppConn COM Connector option in the Development Kit or Server Kit installation on Windows.

Java Connector

The VHI Java Connector is designed to work on any operating system that supports Java 2 Platform, Standard Edition (J2SE) or Enterprise Edition (J2EE), including 64-bit operating systems. The following Java Runtime Environment (JRE) versions are supported by Host Integrator.

For more information on the JRE, see http://java.sun.com.

The Java connector .jar files (apptrieve.jar, vhiprop.jar, wcp.jar) are installed with either Development Kit or Server Kit (to the <VHI>/lib/java directory) and must be added to your CLASSPATH.

C Connector API

On Windows, the VHI C Connector is included in installation of the VHI COM Connector. The appconn.dll and xerces-c_1_4.dll files are installed in your Windows System32 directory.

On UNIX, the directory containing libappconn and libxerces-c1_4 files must be added to your LD_LIBRARY_PATH environment variable (on Linux or Solaris) or LIBPATH environment variable (on AIX). The Server Kit installs these files to the <VHI>/lib directory.
