System Requirements for RPC-MQ Applications

In order to use the message-queuing transport in an RPC client/server application, the server and client machines must have the appropriate operating system platform and Microsoft Message Queuing software installed.

Requirements for server machines are:

• Windows NT® Server, version 4.0 and Service Pack 3, or later. A forthcoming version of DCOM 95 will provide MSMQ support for Windows® 95. Windows® 97 will support MSMQ.
• SQL Server, version 6.5 or later.
• Microsoft Message Queuing Primary Enterprise Controller or Primary Site Controller.
• RPC server-side transport DLL (RpcMqSvr.dll).

Requirements for client machines are:

• Windows NT, version 4.0 and Service Pack 3, or later. Support for Windows 95 is available with the second release of DCOM 95. Windows 98 will support this function.
• Microsoft Message Queuing Client.
• RPC client-side transport DLL (RpcMqCl.dll).

When the Microsoft Message Queue components are installed on the client and server machines, the system registries are automatically configured to include the ncadg_mq message-queuing transport protocol for remote procedure calls.

For detailed information on installing the Microsoft Message Queue Server components see the MSMQ Administrator's Guide.

Program Development

To build your RPC-MQ application you need the following:

• Windows 4.0 and Service Pack 3, or later version. Service Pack 3 contains new RPC runtime DLLs, new RPC header files, and a new rpcss.exe.
• MIDL, version 3.1.76 or later.
