While there are a variety of ways of interacting with GemStone/S 64 Bit, the most basic way is to use Topaz, the command-line GemStone C Interface (GCI) client that has been part of GemStone since the beginning. While GemStone/S 64 Bit as a server is not available for Microsoft Windows, Topaz is available as a Windows client application that can be used to connect to a Unix/Linux/Mac server. Using Topaz is very helpful in debugging connectivity problems since it removes the variables associated with other client applications (such as GBS, GemTools, Jade, etc.). That is, if you are having trouble connecting with GemTools, we are likely to ask you to try to connect using Topaz.

Fortunately, it is relatively easy to run Topaz on Windows. Open a web browser on http://seaside.gemstone.com/downloads/x86.Windows_NT/ and download GemBuilderC3.1.0.1-x86.Windows_NT.zip (this assumes that you are connecting to a server). Unzip this into a convenient location on your Windows machine (e.g., C:\gemstone\). Open a command shell (Start, All Programs, Accessories, Command Prompt), navigate to the ‘bin’ directory created by unzipping the download, and start ‘topaz’. At this point you can enter the usual Topaz commands and try to login to your server. Following is a copy of the screen when I used Topaz on Windows to login to my database:

The things I typed are in bold. The things you need to change are in italics. Specifically, you need to provide the name of your stone (perhaps it is ‘seaside’), the IP address (or hostname if you have an entry in your hosts file) and port number (or service name if you have an entry in your services file) for your NetLDI that will start your gem.
