DESCRIPTION IBM Software Servers IBM Software Servers, a family of modular application servers, enable you to rapidly implement client/server applications and extend application capabilities to meet future business requirements. To meet today's requirement for software that is easy to install, use, and operate while working with existing systems, IBM has taken proven software technology, enhanced it with additional function, and integrated packaging and simpler terms and conditions. The IBM Software Servers announced today are: o Communications Server o Database Server o Directory and Security Server o Internet Connection Server o SystemView(R) Server o Transaction Server o Lotus Notes Together, these servers represent the widest range of application servers in the industry. Refer to the Overview: IBM Software Servers, Software Announcement 296-071, dated March 12, 1996. As part of the IBM Software Server family, the Communications Server for OS/2 Warp, Version 4 is available for IBM's OS/2 Warp Server, Version 4 operating system. Communications Server key characteristics: o The Communications Server has proven technology with unequaled depth-of-function The Communications Server provides PC-to-Host and PC-to-PC multiprotocol communications services. It is an open system that provides full-function, cost-effective support for multiple LAN- or WAN-attached OS/2, Windows 3.1, Windows 95, Windows NT, or DOS PCs, to access System/390(R) and AS/400 hosts, through one or more physical connections to one or more hosts. The Communications Server provides: - Capacity to grow. -- Supports up to 2,000 clients and more than 20,000 simultaneous host sessions - Multiprotocol support. -- Allows Sockets applications to communicate without change, over SNA Networks, or over connected SNA and TCP/IP networks -- Allows SNA applications to communicate without change, over TCP/IP networks, or over connected TCP/IP and SNA networks - APPN network-node, end-node, and APPC support for distributed applications. - APPN High Performance Routing (HPR) support to improve the availability and throughput of your network. HPR gives you improved network availability through transparent recovery from network failures, improved network performance through enhanced error recovery mechanisms, and state-of-the-art congestion control capabilities for reduced bandwidth requirements. - Support for a rich set of 32-bit APIs. - Support for a broad range of LAN and WAN protocols including SDLC, X.25, IDLC, FDDI, ATM, and Frame Relay (when combined with RouteXpander/2). - Remote access to SNA applications over asynchronous, synchronous, Hayes Autosync, digital, and cellular connections. - Support for a wide range of adapters and modems. o The Communications Server protects your investment by working with your existing systems. Communications Server protects your investments in existing Communications Manager/2 (CM/2) installations. Applications written to the APIs in CM/2 work unchanged with Communications Server. CM/2 gateway and APPN network installations are easily migrated to Communications Server through the server installation process. Communications Server protects your investments in existing emulators. The Communications Server supports existing IBM and non-IBM 3270 and 5250 terminal emulators. For example, IBM emulator products such as CM/2 and the Personal Communications family of products will work without change through the Communications Server. Communications Server also protects your investment in SNA communications network support while giving you the freedom to adapt to changing network needs. It provides multiprotocol support that enables you to expand the scope of your existing SNA or TCP/IP network to embrace multiprotocol traffic. Investments in networking skills, operating procedures, and hardware can be preserved and leveraged. You can interconnect networks, without impacting applications, and reduce operational and management costs at the same time. o The Communications Server provides a growth path for your systems. Communications Server works with other IBM Software Servers or works in a stand-alone environment. Version 4 of the IBM Software Servers was validated to work together through IBM integration testing to run on top of IBM OS/2 Warp Server, Version 4. The testing included short and long runs under stressed environments. As your business needs grow, you can add other IBM software servers to complement the communications functions. Communications Server Packaging The Communications Server for OS/2 Warp, Version 4 package has a CD-ROM that contains the following: o Communications Server Communications Server is based on the industry-leading CM/2. For customers with gateway and APPN network node requirements, Communications Server is the natural migration path from CM/2. The Communications Server provides the following: - Multiprotocol gateway support - Capacity to support up to 2,000 clients and more than 20,000 simultaneous host sessions - 32-bit OS/2 APIs - Local and wide area connectivity support - APPN network node and end node - SNA network support and systems management - Installation and configuration support Communications Server provides the IBM Personal Communications/3270 for OS/2 Entry Level emulator for administrative use at the server. It is not to be used in production and cannot be distributed to workstations attached to the server. If you need a full-function emulator, the Personal Communications (PCOMM) Family of emulators is the recommended migration path. Access Features The following is a description of the Communications Server and OS/2 Access Feature function. Communications Server and OS/2 Access Feature are generally referred to as Communications Server. Unless otherwise noted, the description of the functionality applies to both Communications Server and OS/2 Access Feature. o OS/2 Access Feature: The OS/2 Access Feature provides multiprotocol support and APIs for OS/2 desktop workstations connected to the server. The OS/2 Access Feature, combined with one of the OS/2 PCOMM emulators, provides a powerful combination of APPC, APPN, and emulation for the OS/2 desktop workstation. The OS/2 Access Feature provides: - Multiprotocol access node support (used in conjunction with the Communications Server multiprotocol gateway support) - 32-bit OS/2 APIs - LAN and WAN connectivity support - APPN end node - SNA network support and systems management - Installation and configuration support The OS/2 Access Feature is an optional feature that is not required for connection to the gateway. o Windows Access Feature: The Windows Access Feature provides multiprotocol support and APIs for Windows desktop workstations connected to the server. It is a bundle of two products that provide APPC programming support that enables APPC and CPI-C applications to run unchanged over either SNA or TCP/IP LANs and WANs. The products are: - IBM APPC Networking Services for Windows Version 1.0.1 (refer to Software Announcement 294-562, dated September 20, 1994) - IBM AnyNet APPC over TCP/IP Version 1.0 for Windows (refer to Software Announcement 295-110, dated March 21, 1995) The Windows Access Feature is optional and is not required for connection to the gateway. Communications Server License The license for the IBM Communications Server for OS/2 Warp, Version 4 includes a license for: o The IBM Communications Server for OS/2 Warp, Version 4. o The OS/2 Access Feature distributed feature. o The IBM Personal Communications/3270 for OS/2 Entry Level emulator for use on the IBM Communications Server for OS/2 Warp, Version 4 only. It is not to be used in production and cannot be distributed to workstations attached to the server. The license for the IBM Communications Server for OS/2 Warp, Version 4 does not include the right to use the Windows Access Feature. The Windows Access Feature distributed feature license must be ordered separately. The access features are designed for use on desktop machines other than the Communications Server. These features may be ordered only after the Communications Server has been ordered or acquired. Multiprotocol Support Communications Server and OS/2 Access Feature have incorporated the versatile SNA over TCP/IP and Sockets over SNA functions from the AnyNet product family. This support enables you to extend and simplify your network by allowing SNA applications to communicate across a TCP/IP network, and Sockets applications to communicate across an SNA network, without changes to the applications. Communications Server provides these multiprotocol functions: o Sockets over SNA With Sockets over SNA support, Sockets applications can communicate over SNA networks, or over connected SNA and TCP/IP networks, without changes to the applications. In addition, Sockets over SNA users on TCP/IP can benefit from advantages built into SNA networks, such as cost-effective bandwidth utilization and predictable response times. Sockets over SNA support can be used in a variety of ways: - Sockets applications can run on an SNA network A user can use Sockets applications, such as FTP, Telnet, and NFS, across an SNA network, without having TCP/IP connectivity on the network. An SNA Internet Web site can be browsed from client workstations with Web browsers. - Sockets applications can run across connected TCP/IP and SNA networks SNA workstation users can access the World Wide Web using any Web browser, or users on the Internet can access a Web Server in an SNA network. SNMP agents on a TCP/IP network can send management data to an SNMP manager, like NetView(R)/6000, on an SNA network. - Sockets applications can run between TCP/IP networks connected by SNA networks FTP, Telnet, SAP R/3, and Web browser applications can communicate between two workstations on separate TCP/IP networks that are joined by an SNA network. o SNA over TCP/IP With SNA over TCP/IP support, APPC and dependent LU applications (for example, printer or emulator applications) can communicate over TCP/IP networks, or over connected TCP/IP and SNA networks. You can use SNA over TCP/IP support in these ways: - APPC applications can run on a TCP/IP Network APPC applications, such as DB2(R) and CICS(TM), can run over TCP/IP with no changes to the applications and with no need for SNA to be on the network. - APPC applications can run between connected SNA and TCP/IP networks APPC applications, such as DB2, on an SNA network can communicate with DB2/2(TM) applications on a connected TCP/IP network. - APPC applications can run between SNA networks connected by TCP/IP networks DB2, CICS, and IMS(TM) applications can be used between two workstations running on two separate SNA networks, which are joined by a TCP/IP network. SNA Gateway (Communications Server only) The Communications Server provides a rich, cost-effective SNA gateway. The gateway enables multiple LAN- or WAN-attached OS/2, Windows 3.1, Windows 95, Windows NT, or DOS workstations to access multiple System/390 hosts through one or more physical connections to one or more hosts. The gateway is optimized to provide cost-effective host connectivity by sharing communications resources such as adapters and physical connections. Communications Server SNA gateway enhancements: o SDLC now supports 16 (or more) upstream and downstream physical connections, and two-way, simultaneous, full-duplex communications. o The WAN line speed has been increased to 2.0 Mbps (T1/E1) (or greater). o Communications Server can now act as the multipoint primary control for downstream workstations. This support is for workstations and devices connected to the server over SDLC, on a multi-drop line over synchronous adapters such as the IBM Wide Area Connector (WAC), Multiprotocol Communications Adapter (MPA/MPCA), and an IBM Real Time Interface Coprocessor (RTIC). o Dependent LU support across a TCP/IP network with SNA Subarea and APPN support upstream from the configured gateway. o Dependent LU support across an SNA network with TCP/IP support upstream from the configured gateway. o Automatic host backup links can be defined for automatic activation should the primary link fail. Advanced Peer-to-Peer Networking Communications Server APPN support provides SNA networking facilities to connect distributed computing applications, peer applications, and client applications to their servers. These facilities include directories of partners, route selection, and management services. APPN provides support to: o Add, delete, or move nodes within the network with limited system definition at the affected node, and no other definition at other nodes. o Use APIs to automate configuration changes, add network management capabilities, and use defaults for reducing required system definition. o Significantly improve performance of communications between APPC and CPI-C 2.0 applications, especially in a LAN environment. o Use the CPI-C interface for enabling greater application portability across different platforms. o Use additional debugging tools and sample programs for easily developing and using APPC and CPI-C applications. Communications Server APPN function enhancements: o High Performance Routing Communications Server provides support for HPR, the advanced, open technology that quickly and smoothly routes data across a network. HPR offers advantages not available with other networking solutions: - Combines the best features of IP, SNA, Frame Relay, and APPN. - Increases network availability by non-disruptively rerouting around network failures. - Implements state-of-the-art congestion control capabilities for reduced bandwidth requirements or more efficient use of existing bandwidth. - Positions customer networks for a smooth transition to ATM because it was specifically designed for high-speed environments. - Provides an excellent transport for the integration of multiprotocol traffic. - Improves network performance. HPR is an end-to-end, connection-oriented protocol that can be visualized as a pipe between two nodes. HPR provides capabilities that optimize communications across the pipe. These capabilities include: - Improve network availability through end-to-end connections, alternate route calculations, and transmission resumption if an intermediate link or node fails. - Improve network performance by only performing error recovery at the endpoints of the network and by selectively retransmitting only lost or erroneous packets. - Improve SNA's congestion control by constantly monitoring and adjusting the amount of data flowing between the endpoints, ensuring they do not overload. Communications Server support of HPR provides the following capabilities: - Communications Server defined as an APPN node (end node or network node) can function as an endpoint for an HPR session. - Communications Server defined as a network node can also function as an HPR intermediate node. - Communications Server supports HPR routing over token-ring, Ethernet, FDDI, LAN/ISDN, and Frame Relay connections. o Dependent LU requester Dependent LU requester (DLUR), in conjunction with VTAM(R)'s dependent LU server (DLUS) function, enables dependent LUs (LU0, 1, 2, 3, and dependent LU6.2) to operate unchanged in an APPN network, without changing applications. The DLUS establishes an LU6.2 session with, and provides SSCP services to, the DLUR node. Any number of dedicated physical units (PUs) can be defined on the LU6.2 sessions. The Communications Server gateway can then provide network management access through the dedicated PU to downstream workstations. DLUR lets you protect your investment in 3270 emulation and other dependent LU applications while migrating new applications to LU6.2 and APPN. o LU6.2 Sync Point Enablement Communications Server now has LU6.2 Sync Point support. This function allows distributed transaction coordinators, such as DB2 for OS/2, to provide products that implement two-phase commit protocols. These protocols, referred to as Sync Point managers, can be invoked by an application program to define synchronization points (sync points) where all changes to distributed resources are consistently either committed or backed out, even if errors or failures occur. Sync Point managers make it easier for programmers to write reliable, distributed applications programs by reducing the application logic required to recover from application errors, system failures, and network failures. IBM has announced the following Sync Point managers built on the LU6.2 Sync Point Support (refer to Software Announcement 296-021, dated January 30, 1996): - Distributed Relational Database Architecture(TM) (DRDA(R)), Sync Point Manager Support of DB2 for OS/2 Version 2.1.1 - Distributed Database Connection Services (DDCS), for OS/2 Multi-User Gateway Version 2.3.1 o Self Defining Dependent LU (SDDLU) Communications Server can now dynamically identify its dependent LUs to VTAM and eliminate the requirement for a static definition of dependent LUs in VTAM (for example, no VTAM SYSGEN required). o SNA Transmission Priority Communications Server provides the capability to prioritize SNA traffic for LU0, 1, 2, 3, and 6.2 sessions over LAN and WAN connections. o System Services Control Point (SSCP) Takeover Communications Server provides the capability to keep sessions active and allow CP name changes when a VTAM/NCP composite node takes over SSCP sessions currently owned by another VTAM/NCP node. o CP-CP Session Reactivation Automatic activation of CP-CP sessions or reactivation of CP-CP sessions that have failed prevents network nodes from being detached from the network as long as at least one link is active. o APPC Full Duplex APPC now supports full-duplex, logical conversations and non-blocking verbs for LU6.2 applications. This enhancement simplifies APPC applications logic and greatly improves performance. Programming Support The following APIs are now available as native 32-bit APIs: o Asynchronous Communications Device Interface (ACDI) o APPC o CPI-C o Communications Server Kernel Interface o Common Services o Conventional LU Application (LUA) o X.25 API Communications Server has been tested and provides 32-bit header files for the IBM C Set++ and Borland C++ programming languages. You can use other compilers and languages if you develop header files for them. Communications Server continues support for all of the 16-bit APIs available in Communications Manager/2 Version 1.1. These 16-bit APIs will not be enhanced. Emulator Support The terminal emulator previously provided in Communications Manager/2 has been removed. Terminal emulation for administrative use at the server is provided by PC/3270 for OS/2 Entry Level (PC/3270 Entry). The PC/3270 Entry emulator supports up to two 3270 display sessions with a S/390, via Communications Server LUA support. The functions provided by this emulator are a subset of the functions provided by the IBM Personal Communications/3270 for OS/2 emulator. Connectivity Enhancements o SDLC SDLC has been expanded to include: - Use of switched and leased lines at the same time - WAN line speed up to 2.0 Mbps (T1/E1) or greater - Coexistence with LAN Distance(TM) product - Programming of IRQ levels on ISA bus workstations SDLC has also been enhanced to support 16 (or more) physical connections and two-way simultaneous, full-duplex communications. o SDLC Multipoint Primary Server Communications Server can now act as the multipoint primary control for downstream workstations. This support is for workstations and devices connected to the server over SDLC, on a multi-drop line over synchronous adapters, such as the IBM WAC, MPA, and ARTIC. o Automatic Host Backup Link (Communications Server only) Each primary link can be defined with a secondary or backup link. This backup link is automatically activated when the primary link fails. o ATM Communications Server supports the TURBOWAYS(TM) ATM 155, 100 Mbps and 25 Mbps adapters in LAN Emulation mode. o LAN Physical Connections Communications Server supports 16 (or more) physical connections over token-ring, Ethernet, and PC Network. Shallow and Deep Adapter Support Communications Server now supports nonprogrammable ("shallow") and programmable ("deep") adapters for both Micro Channel(R) and ISA-bus workstations using a set of open interfaces. These interfaces allow IBM and other vendors to provide connectivity for Communications Server over ISDN, SDLC, X.25, or other data link controls. As of March 1996, the following list of vendors have adapters and drivers that have been implemented to the open device driver interfaces. These drivers are included on the Communications Server CD-ROM: o IBM - ARTIC - MPA/MPCA - WAC - WAVERUNNER(TM) Digital Modem (driver not on CD-ROM) o Eicon Technology Corp. - Eicon Card S51 for X.25, Frame Relay, and ISDN o Microgate Corporation - Microgate Digital Services Adapter (DSA) for SDLC and Asynch The following vendors have indicated they plan to provide device driver support to the new open adapter interface. You should check with your vendor or distributor of adapters to find out which cards they have made available on this interface. o ARN Informatique o Atlantis SAT o Digi International o Sangoma o Synaptel o TELDAT S.A.

The gateway enables multiple LAN-attached OS/2, Windows, or DOS workstations to access multiple System/370(TM) or System/390 hosts through one or more physical connections to one or more hosts. The gateway is optimized to provide cost-effective host connectivity by sharing communications resources such as adapters and telephone connections. The Communications Server gateway supports: o SNA protocols LU0, 1, 2, 3, and dependent LU6.2 (APPC). The gateway also supports LU0, 1, 2, or 3 to an AS/400 host using SNA pass-through. o Multiple physical unit type 2.0 (PU2.0) and up to 254 logical units (LUs) per PU. To increase efficiency, LUs may be dedicated to a workstation or pooled among workstations. o Up to 254 concurrently active workstations per LAN adapter to transparently access one or more System/390 hosts. Implicit workstation definitions simplify gateway configurations and management since downstream workstations are not required to be configured on the Communications Server for OS/2 Warp, Version 4. o Downstream applications and workstations using standard SNA connectivity protocols for LU0, 1, 2, 3, and dependent 6.2, and communicating through an SNA Gateway to a host. The downstream workstations include Novell NetWare for SAA and Apple Macintosh SNAps Gateway. o Dedicated and pooled LU definitions. The LUs defined in the gateway can be dedicated to a particular workstation or pooled among multiple workstations. Pooling allows workstations to share common LUs, which increases the efficiency of the LUs and reduces the configuration and startup requirements at the host. You can also define multiple LU pools, each pool associated with a specific application. When a link is defined through the gateway between a workstation and the host, the LU is activated when the session is established and returned to the pool for access by other workstations when the session is ended. o Automatic host backup link that enables each primary link to be defined with a secondary or backup link. This backup link is automatically activated when the primary link fails. o Session inactivity management that supports configuration of an SNA gateway to automatically stop a session after a specified period of inactivity if there are other workstations waiting. This procedure helps increase the number of available shared LUs. o The transmission of network management vector transports (NMVTs) between the gateway and the host. For example, commands coming from the NetView program in the host are received in the gateway and may be passed to and used by another application on the gateway, such as IBM LAN Network Manager. Each host views the SNA gateway as an SNA PU2.0 node, supporting one or more LUs per workstation. As far as the host is concerned, all LUs belong to the SNA gateway PU. The SNA gateway can have multiple host connections simultaneously and can direct different workstation sessions to specified hosts. Only one host (and it must be on a link with a CP PU) can act as the focal point, and the CP name is appended to all NMVTs routed through the gateway. o SDLC now supports 16 (or more) upstream and downstream physical connections, and two-way, simultaneous, full-duplex communications. o The WAN line speed increased to 2.0 Mbps (T1/E1), or greater. o Communications Server can now act as the multipoint primary control for downstream workstations. This support is for workstations and devices connected to the server over SDLC, on a multi-drop line over synchronous adapters such as the IBM WAC, MPA, and RTIC. o Dependent LU support across a TCP/IP network with SNA subarea and APPN support upstream from the configured gateway. o Dependent LU support across an SNA network with TCP/IP support upstream from the configured gateway.

These products can also interoperate with window applications that communicate across the network using the appropriate networking and application protocols. Communications Server will migrate control files and other pertinent user-modified information from EE 1.3, ES 1.0, CM/2 1.0, and CM/2 1.1. Code will be upgraded from the previously listed releases of CM/2 and AnyNet (except for EE 1.3). Planning Information Customer Responsibilities: Problem determination (PD) is a customer responsibility. PD is an assessment of whether a problem has been caused by hardware or software. PD is not complete until the cause of the problem is identified. This assessment includes examination of available symptoms using the PD procedures documented in the Communications Server publications. Problem source identification (PSI) is a customer responsibility. PSI begins when software is determined to be the source of the problem. PSI includes tracing the source of the problem to a host system control program, an application program, or another source. Assisting the customer with PSI is an IBM service and support responsibility. Installability: Communications Server can be installed directly from a CD-ROM drive or via the Configuration, Installation, and Distribution (CID) process. Packaging: The Communications Server package also has the following materials: o Up and Running! o IBM Personal Communications AS/400 and 3270 brochure o Registration card o IBM International Program License Agreement o License Information Booklet o Service entitlement information card o Proof of License Security, Auditability, and Control When using the System/370 Remote Operations Support (ROPS) for NetView, and a RUNCMD is issued, all information is transmitted in the clear and is not secured. This transmitted information may include the user ID and password. Transmitted information is also displayed on the screen and is entered in the NetView log. The display on the NetView operator's screen and in the NetView log can be avoided by using the NetView suppression character when the RUNCMD is issued. If passwords are transmitted to the ROPS service, the user is responsible for securing the NetView terminal and the NetView logs so that sensitive data is not compromised. User management is responsible for evaluation, selection, and implementation of security features, administrative procedures, and appropriate controls in application systems and communication facilities.
