2. Configuring GBS for GemStone/S 64 Bit
While the GemStone/S 64 Bit Windows Client provides a number of server utilities that can be run on Windows, the primary purpose of the GemStone/S 64 Bit Windows Client is to provide the libraries that support client applications on Windows, such as GemBuilder for Smalltalk (GBS) client applications.
For instructions for updating GBS clients that are running on Linux, see the GemStone/S 64 Bit Installation Guide for Linux. GBS clients are not supported on Solaris, AIX, or Macintosh.
For a table of all supported GBS and client Smalltalk platforms, see the GemStone/S 64 Bit Release Notes for v3.4.
This chapter describes how to configure or update your client Smalltalk application using GBS on Windows to run with a GemStone/S 64 Bit version 3.4 server.
The GemStone/S 64 Bit v3.4 server requires a compatible version of GBS; versions of GBS earlier than v8.3 for VisualWorks Smalltalk, or v5.4.4 for VA Smalltalk, cannot be used with GemStone/S 64 Bit v3.4 or later.
In addition to using the appropriate version of GBS, you must use GemStone/S 64 Bit 3.4 client libraries with your GBS client application, to be able to log in to the v3.4 server. These libraries are specific to the GemStone/S 64 Bit server version and to the client platform. Only RPC logins are available from Windows.
The GemStone/S 64 Bit Windows Client provides both 64-bit libraries and 32-bit libraries.
- With 64-bit VisualWorks environments, you must use the 64-bit GemStone client libraries
- With 32-bit VisualWorks and VA Smalltalk environments, you must use 32-bit libraries.
For instructions on installing and configuring GBS, see the GemBuilder for Smalltalk Installation Guide for the appropriate version of GBS.
Supported GBS client Smalltalk Platforms with Windows
The following client Smalltalk versions are supported on Windows platforms:
GemBuilder for Smalltalk/VW v8.3
GBS Setup or Upgrade Procedure
Shared Libraries for GBS Client Node
The GBS client requires a set of shared libraries (.dlls) that are provided as part of the GemStone server product distribution. Since the GemStone/S 64 Bit server itself is not available for Windows, the Windows Client distribution is provided, which includes the shared libraries as well as other server utilities that can be run on Windows.
When these client shared libraries are loaded into the VisualWorks or VA Smalltalk image in which GBS code is installed, the GBS client can log into the GemStone server.
The shared libraries must be the same version as the GemStone server. Since they are loaded into the client smalltalk VM, they must be appropriate for the client platform and client executable bit size (32-bit or 64-bit).
You can either install the full GemStone/S 64 Bit Windows Client on your GBS client node, or just copy the specific shared libraries you need.
Full GemStone/S 64 Bit Windows Client installation on client node
One option for installation is to install the complete GemStone/S 64 Bit Windows Client on the client machine.
In addition to the shared libraries, the GemStone/S 64 Bit client installation includes tools such as topaz, gslist, and VSD, that may be useful to run on your client.
To perform this installation, follow the instructions in Chapter 1 of this Installation Guide.
Libraries only
If you do not require tools such as gslist, vsd, or topaz on the client, you do not need to install the full GemStone/S 64 Bit Windows Client on the client node. You may just copy the set of library files that GBS requires.
32-bit VisualWorks or VA Smalltalk clients:
For RPC logins from 32-bit VisualWorks or VA Smalltalk, the following files need to be copied to the client node:
%GEMSTONE%\bin32\libgcirpc-3.4.0-32.dll
%GEMSTONE%\bin32\libssl-3.4.0-32.dll
%GEMSTONE%\bin32\msvcr100.dll
64-bit VisualWorks clients:
For RPC logins from 64-bit VisualWorks, the following files need to be copied to the client node:
%GEMSTONE%\bin\libgcirpc-3.4.0-64.dll
%GEMSTONE%\bin\libssl-3.4.0-64.dll
%GEMSTONE%\bin\msvcr100.dll
GBS provides a number of options as to where to place the shared libraries on the client machine. Refer to the GemBuilder for Smalltalk Installation Guide for details on these options.
Upgrade GBS to a version that supports v3.4
Versions of GBS earlier than 8.3 for VisualWorks and 5.4.4 for VA Smalltalk are not supported with GemStone/S 64 Bit v3.4 or later.
If you are currently running with an older version of GBS, you will need to upgrade the GBS client, and possibly also upgrade VisualWorks or VA Smalltalk to a more recent version, in order to use these clients with v3.4.
See the GemBuilder for Smalltalk Installation Guide for installation instructions, and the GemBuilder for Smalltalk Release Notes for details on the changes in these versions.
Update GBS to reference v3.4 libraries
Once you have installed the GemStone server on the GBS client machine, or copied the appropriate shared libraries, you need to ensure that the client Smalltalk executable – a VisualWorks or VA Smalltalk application – will load the v3.4 libraries.
Determining library name to specify
Whether or not you have a full GemStone/S 64 Bit Windows client installation on the client or have copied a few libraries, there is a specific library name you will specify to have GBS load using the libraryName: parameter.
Setup GBS to load the new libraries
- If you have set the GBS configuration parameter libraryName:, update this to the new library name, and save your image.
- If you have set the GBS configuration parameter libraryName: to an empty string, ensure that no other client libraries of the same name are in the current working directory or the bin directory or subdirectory of your VisualWorks image’s VISUALWORKS directory. This is not applicable to VA Smalltalk.
- For a new GBS application, refer to the GemBuilder for Smalltalk Installation Guide for details on the library loading setup options.
