Compaq Software Product Description ___________________________________________________________________ PRODUCT NAME: Compaq[R] SNA Server SPD 70.89.00 for OpenVMS[TM] Alpha, Version 1.0 DESCRIPTION Compaq SNA Server for OpenVMS is a layered software product that al- lows suitably configured OpenVMS Alpha[TM] systems to directly par- ticipate in an IBM[R] Systems Network Architecture (SNA) networking environment. After installing the SNA Server for OpenVMS and one or more SNA access routines, users can perform functions such as access- ing IBM application programs or other system resources, act as a 3270 display station, exchange data files and documents with an IBM host, and implement distributed application programs that run between the OpenVMS Alpha and IBM systems. Architecturally, an OpenVMS Alpha system running Compaq SNA Server for OpenVMS appears to the SNA network as a Physical Unit Type 2.0 node, and is attached to the SNA network through a synchronous communica- tions device to an IBM 37xx Communications Controller. The SNA server software supports one synchronous communications line. The SNA server software supports a maximum of 255 concurrent SNA logical unit ses- sions. Your session limit and line speed will depend on the Alpha CPU and memory on which the SNA server is running. Both local and remote (DECnet or TCP/IP) connections are supported from the Compaq SNA server into the IBM SNA network, using switched or leased lines in point-to- point or multipoint environments. Compaq SNA Server for OpenVMS also supports connections over X.25 switched virtual circuits using Qual- ified Logical Link Control (QLLC). The X.25 for OpenVMS Alpha prod- uct is required for SNA over X.25 connections. January 2000 AE-RJ1TA-TE Users on one or more systems with SNA access routines can simultane- ously perform functions such as accessing IBM application programs or other system resources, act as a 3270 display station, perform data transfer between Compaq and IBM file systems, exchange electronic doc- uments and mail messages, submit jobs to IBM batch subsystems acting as a Remote Job Entry workstation, and implement distributed, task- to-task application programs that run between Compaq and IBM systems. Please refer to the DECnet-Plus for OpenVMS Alpha Software Product De- scription (SPD 50.45.xx) for information about the devices supported by the Compaq SNA Server for OpenVMS. Each device supports different configurations. See Table 1 in the Minimum Recommended Configuration section of this product's Software Product Description for details. Connection is via Synchronous Data Link Control (SDLC). SDLC circuits can be set full duplex. Data can be sent and received simultaneously on full-duplex lines. This setting corresponds to DATMODE=FULL in the IBM ACF/NCP PU macro. The functions provided by the SNA server software are comparable to those provided by the DECnet SNA Gateway product. Systems wishing ac- cess to the SNA environment must be configured with the appropriate SNA access routines. For additional information about which access rou- tines are supported, see the Optional Software section of this Soft- ware Product Description. Compaq SNA Server for OpenVMS supports connections over X.25 switched virtual circuits (QLLC) as well as SDLC circuits. The QLLC circuit can be configured to use either incoming or outgoing X.25 switched vir- tual circuits (SVCs). Compaq SNA Server does not support X.25 perma- nent virtual circuits (PVCs). Compaq SNA Server requires the IBM Net- work Packet Switched Interface (NPSI) in order to use QLLC circuits. The IBM NPSI software should be generated to support "Boundary Net- work Node, Qualified Logical Link control" (BNN QLLC) type-3 switched virtual circuits. Compaq SNA Server also supports the following optional facilities for QLLC circuits: o Flow Control Negotiation 2 o Closed User Groups o Reverse Charging Management Utilities The Compaq SNA Server for OpenVMS provides the management utilities SNANCP and SNAEVL. SNANCP is used to manage and monitor SNA server com- ponents such as line, circuit, physical unit (PU), and logical unit (LU). SNANCP provides the human interface for the Compaq System Man- ager to monitor, control, and troubleshoot the SNA server and its IBM SNA environment. All management functions pertaining to SNA server soft- ware are performed on Alpha systems. The SNANCP commands allow users to display and modify information pertaining to the line, circuit, PU, LUs, and access names. Online help is provided. SNAEVL is used to log events generated by these components. Management of the Compaq SNA node should be viewed as part of the Com- paq environment; the management of the line connecting the OpenVMS Al- pha system to the IBM system is a joint responsibility of the IBM and Compaq system managers. Problem Isolation and Determination Tools The Common Trace Facility (CTF) is the problem-determination tool that provides frame-level tracing of a circuit to help in debugging appli- cation programs and identifying system problems. A privileged DECnet- Plus user can run a trace at the PU level, SDLC level, or session level. The trace feature is helpful for identifying an error for remedial ac- tion. The Installation Verification Procedure (IVP) for the Compaq SNA Server for OpenVMS, SNAVMS$IVP, is also useful for problem isolation. SNAVMS$IVP is run separately from any access routine, and can be used to verify connectivity to specific IBM applications over specific LU sessions. In failure cases, SNAVMS$IVP displays an expanded error text that at- tempts to diagnose the cause of the failure. 3 INSTALLATION Compaq suggests purchase of the SNA Installation Service for the first Compaq node connected to each IBM host. Customer Responsibilities Before the SNA Installation Service is performed, the customer must: o Previously have installed all prerequisite hardware and software, including terminals. o Obtain, install, and demonstrate as operational any modems and other equipment and facilities necessary to interface to Compaq's com- munications equipment. o Perform configuration and test the operational status of the syn- chronous modems for the communications line. o Have generated, to Compaq's satisfaction, any necessary IBM host software that will be communicating with the SNA server software. o Have installed DECnet-Plus for OpenVMS Alpha (on systems running OpenVMS V7.1 or 7.2A). For installation requirements, refer to the DECnet-Plus for OpenVMS Alpha Software Product Description (SPD 50.45.xx). o Have completed any additional requirements as described in the SNA Installation Service. o Make available for a reasonable period of time, as mutually agreed on by Compaq and the customer, all hardware, communications facil- ities, and terminals that are to be used during installation. o Be prepared to work with the Compaq and IBM system managers in the preinstallation activities outlined in the SNA Installation Ser- vice. o Be prepared to modify IBM component generation parameters to sup- port the SNA server software.
