System Requirements

The VMware GemFire native client provides access for C++ and Microsoft® .NET™ Framework clients to the GemFire distributed system. It operates on platforms running Microsoft Windows, Linux (Intel), and Tanzu Application Service.

GemFire Compatibility

The GemFire Native Client supports applications that communicate with GemFire servers. Native Client version 10.4 works with Pivotal GemFire versions 9.0.0 and later.

The following table shows which versions of the Native Client are compatible with the various versions of the GemFire server.

GemFire Native Client Version	GemFire Server Version
GemFire Native Client 10 GemFire Native Client 9.1, 9.2	GemFire Server 9.x
GemFire Native Client 9.1 GemFire Native Client 8.2	GemFire Server 8.2

Application Compatibility

GemFire Native Client is compiled using 64-bit architectures for all operating systems. Linking with 32-bit applications is not supported.

Supported Platforms: .NET Framework Client

Platform	Version
Windows Desktop	10
Windows Server	2016
Tanzu Application Service	TAS 2.10+

.NET Framework Compatibility

For Windows applications, a Microsoft .NET Framework must be installed to support the C++/CLI (Common Language Infrastructure) library for the native client.

The client supports .NET Framework 4.5.2 (and newer) and Visual Studio 2017 (and newer) for compiling .NET Framework applications on Windows. It does not support .NET Core. For more information on the features of .NET Framework and Visual Studio Community Edition 2017, see the Visual Studio 2017 web page.

Host Machine Requirements

Each machine that runs a native client must meet the following requirements:

• A system clock set to the correct time and a time synchronization service such as Network Time Protocol (NTP). Correct time stamps permit the following activities:
  • Logs that are useful for troubleshooting. Synchronized time stamps ensure that log messages from different hosts can be merged to reproduce an accurate chronological history of a distributed run.
  • Aggregate product-level and application-level time statistics.
  • Accurate monitoring of the system with scripts and other tools that read the system statistics and log files.
• The host name and host files are properly configured for the machine.

TAS Support

Tanzu Application Service supports .NET Framework native client applications.

TAS versions 2.10 and higher include the Microsoft VS 2017 C++ Redistributable DLLs.

TAS .NET Framework Requirements

• TAS 2.10 or newer
• Windows Server 2016
• .NET Framework 4.5.2 or newer

To run your cloud native .NET Framework application on TAS:

1. The Pivotal.GemFire.dll must be in the output folder of your .NET Framework project.
2. Rebuild your application.
3. From Visual Studio, publish your application to a filesystem.
4. From within the published filesystem, use cf push to deploy your application to TAS as you would other .NET Framework applications.

Software Requirements for Using SSL

If you plan on using SSL in your GemFire native client and server deployment, you will need to download and install OpenSSL. The GemFire native client requires OpenSSL version 1.1.1.

For Windows platforms, you can use either the regular or the OpenSSL “Light” version.

In addition, make sure that your system environment variables have been configured to include OpenSSL.
