Windows XP Professional uses TCP/IP as its primary networking protocol suite. IBM host systems, primarily IBM mainframes and AS/400 systems, increasingly use TCP/IP, but many installations still use Systems Network Architecture (SNA). In order for Windows XP Professional based computers to communicate with IBM host systems, either a gateway device to interpret the two different network protocols or a common network protocol is required.
To connect to IBM hosts by using a gateway device, you must have a local area network (LAN) protocol on Windows XP Professional, typically TCP/IP, and a gateway that provides the translation between the LAN protocol and the IBM host protocol or data stream. Microsoft Host Integration Server 2000 is a gateway that provides the translation service to establish network connectivity with IBM host systems.
After SNA-based or TCP/IP-based network connectivity is established, the advanced host integration features of Host Integration Server 2000 allow Windows users to gain secure access to IBM host data, applications, and network services without leaving the familiar Windows desktop or Web browser interface.
The following list describes these host integration services and how they apply to each layer of the Windows 2000 interoperability model.
Network integration. Provides cross-platform network connectivity and protocols, security integration, and single sign-on between clients, including Windows clients, and IBM host systems. The single sign-on feature allows users to log on once for access to multiple servers, systems, or applications.
Data access. Enables transparent file transfer services, universal data access technologies such as OLE DB and open database connectivity (ODBC), and host data replication.
Application interoperability. Provides terminal access, integrated transaction services, and Web-to-host integration.
Network management integration. Network management integration provides integration between Windows XP network management services and IBM NetView based management services.
When Host Integration Server 2000 is implemented as a gateway to an IBM host, Windows XP Professional uses Host Integration Server 2000 client software to establish connectivity. The Host Integration Server 2000 client software (either Administrator s Client or End-User Client) includes terminal emulation programs. For connecting to an IBM mainframe using the SNA 3270 data stream, the 3270 Client is provided. For connecting to an IBM AS/400 system using the SNA 5250 data stream, the 5250 Client is provided.
Administrators can install Host Integration Server 2000 client software on Windows XP Professional based computers. Host Integration Server 2000 Administrator Client allows you to use the interface in SNA Manager or the snacfg command to read and change the configuration file, start and stop services and connections, or reset SNA Logical Units (LUs). Table J-2 describes the components you can select during the installation of Host Integration Server 2000 client software.
| Client Component | Description |
|---|---|
| SNA Manager | Allows you to manage Host Integration Server 2000 from Windows XP Professional. Users who have network administration privileges can use SNA Manager to configure a Host Integration Server 2000 computer, LUs, LU pools, users, Host Print Service, Shared Folders Gateway Service, APPC modes, CPI-C symbolic names, and host security domains. |
| 3270 Client | Allows access to an IBM host on an SNA network. |
| 5250 Client | Allows access to IBM AS/400 systems. |
| COM Transaction Integrator for CICS and IMS (COMTI) | Provides access to IBM Customer Information Control System (CICS) and Information Management System (IMS) programs that run on Multiple Virtual Storage (MVS) mainframes. |
| Microsoft OLE DB Provider for AS/400 and VSAM | Allows record-level access to mainframe and AS/400 files. |
| APPC File Transfer Protocol (AFTP) Client | Allows client computers to connect to the AFTP service to share files across platforms. |
| Host Account Manager | Connects users to all servers and domains to which they have access with a single password. |
| Host Integration Server 2000 Remote Access Service | Enables an administrator to create a virtual LAN connection between Windows Server systems across an existing SNA network without having redundant LAN-to-LAN networks or having to install dial-up connections at each site. |
| Host Connectivity SDK | Provides access to the Software Development Kit (SDK), making it possible for software developers to create specialized Host Integration Server 2000 applications. |
| SNA NetView Alerter | Allows the IBM NetView reporting system to send alerts and other messages between a host and the computers that connect to it. |
