Description

IBM Communications Server for Windows NT and

Windows 2000 provides all-in-one communications

services between workstations and a host system, as well

as other workstations. Its capabilities include a

full-function SNA gateway, the most Advanced

Peer-to-Peer Networking

 system in the industry, support

for many types of connectivities, and a rich set of

application programming interfaces (APIs). Of particular

significance is the support of SNA, that is based on IBM′s

long experience as the architect and developer of this

important protocol. In addition, the Communications

Server opens the door wide to protocol-independent

networking, with seamless support for workstations

communicating across SNA and TCP/IP networks. This

gives companies the freedom to be responsive to the

changing demands of business applications, while

minimizing network impact.

The following is a summary of the new functions and

enhancements.

Express Logon

This function allows a user, running an express

logon-capable TN3270E client, to log onto popular

OS/390

 host subsystems, such as CICS , IMS , and

TSO, without having to enter a RACF

 user ID and

password. Instead, an X.509 digital certificate is

processed in cooperation with RACF to authenticate the

user. One advantage of using this function is that it may

reduce the time spent by an administrator maintaining

host user IDs and passwords. It may also reduce the

number of user IDs and passwords that users have to

remember. The TN3270E client and the Communications

Server for OS/390 must also provide the express logon

function. Currently, this support is offered in WebSphere

Host On-Demand Version 5.0 and Communications

Server for OS/390 Version 2 Release 10.

Active Directory

Communications Server now publishes to the

Windows 2000 Active Directory that it has TN3270 and

TN5250 server capability. This permits any Windows 95,

98, NT, or Windows 2000 client machine to search for and

find the Communications Server′s TN3270/TN5250

services configured within Active Directory, allowing the

client to connect to the server. This works for

applications using the Lightweight Directory Access

Protocol (LDAP) Version 3 APIs or Active Directory

Services Interface (ADSI) on a Windows 95, Windows 98,

Windows NT, or Windows 2000 client. This saves

configuration efforts and expands the benefit to more

types of clients. Previously, the only way to get this

information was through Service Location Protocol (SLP)

which required configuration on the Communications

Server and its use was limited to only the

Communications Server for Windows NT clients.

To query the Active Directory function the clients must

use either LDAP Version 3 or ADSI APIs. These are

included in the Windows 2000 operating system. They are

available for downloading from the Microsoft Web site for

the other platforms.

Host Publisher

The Host Publisher feature can enable new uses for

existing applications and data. With this capability, you

can combine existing information sources into composite

applications for new users, without any changes to the

existing applications and data. The business benefits

associated with Host Publisher are substantial.

Host Publisher consists of two major components:

• Host Publisher Studio

• Host Publisher Server

Host Publisher Studio:

The Host Publisher Studio is a

collection of task-oriented, easy-to-use GUIs that assist

the Web application builder in managing and creating

Web-to-host projects. It uses task-oriented prompts to

guide the user through the creation process, including:

• Recording host and database interactions

• Identifying desired data

• Labeling that data for retrieval

The Host Publisher Studio is provided on a separate CD

assembly and runs on Windows 95, Windows 98,

Windows NT, and Windows 2000 operating systems.

Host Publisher Server:

The Host Publisher Server runs

on Windows NT and provides the run-time environment

for supporting Web applications created with the Host

Publisher Studio. Host Publisher is on a separate CD

assembly and runs on Windows NT only. It consists of the

WebSphere Application Server Standard Edition and other

run-time components such as:

• Connection management

• License monitoring

• Run-time administration

• Log and trace management

The Host Publisher feature also includes a separate CD

assembly for IBM Network Dispatcher to provide load

balancing across multiple Host Publisher Servers. The

Network Dispatcher can only be used for the

load-balancing function for Host Publisher. If you require

load balancing for other applications or servers, you must

purchase these additional copies separately.

Remote Integration Objects (RIO):

RIO support provides

a standard interface for program access to Integration

Object data in an XML format. It also provides remote

access to Host Publisher server Integration Objects. This

enables remote Java applications or applets, running on

a remote client or server, to execute Host Publisher

Integration Objects for an existing application access as

though they were physically running on the Host Publisher

server machine. The interface to the Host Publisher

Integration Objects is unchanged regardless of whether

the customer′s Java application is calling it from a remote

client or is running on the Host Publisher server.

XML Gateway:

The Host Publisher feature provides an

XML Gateway for accessing legacy 3270 and 5250

applications and making that application data available to

programs in an XML format.

The Host Publisher XML Gateway also provides an HTML

Mapper capability that provides a load-and-go HTML

entry-level emulator for 3270 or 5250 application access.

Without any customization, existing 3270 and 5250

applications can be extended to Web users. This

capability is targeted at end users who:

• Need occasional access to the host application

• Consider a native terminal screen look and feel to be

acceptable

• Do not yet have Java-capable desktops

For Java-enabled users, IBM′s Host On-Demand should

be considered to meet their emulation needs.
