Software Product Description ___________________________________________________________________ PRODUCT NAME: Compaq SNA Server SPD 70.89.01 for OpenVMS Alpha, Version 1.1 DESCRIPTION Compaq SNA Server for OpenVMS Alpha (SNA Server) is a layered soft- ware product that allows suitably configured OpenVMS Alpha systems to directly participate in an IBM Systems Network Architecture (SNA) net- working environment. After installing the SNA Server and one or more SNA access routines, users can perform functions such as accessing IBM application programs or other system resources, act as a 3270 display station, exchange data files and documents with an IBM host, and im- plement distributed application programs that run between the Open- VMS Alpha and IBM systems. Architecturally, an OpenVMS Alpha system running the SNA Server ap- pears to the SNA network as a Physical Unit Type 2.0 node, and is at- tached to the SNA network through synchronous communications devices or an X.25 network to an IBM 37xx Communications Controller. The SNA server software supports a maximum of 255 concurrent SNA logical unit sessions per PU. Your total session limit and line speed will depend on the memory and communications options installed on the Alpha CPU 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 Alpha also sup- ports connections over X.25 switched virtual circuits using Qualified Logical Link Control (QLLC). The X.25 for OpenVMS Alpha product is re- quired for SNA over X.25 connections. May 2001 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. Compaq SNA Server supports connections via Synchronous Data Link Con- trol (SDLC). SDLC circuits can be set full duplex. Data can be sent and received simultaneously on full-duplex lines. This setting cor- responds 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-ST product. Systems wishing access to the SNA environment must be configured with the appropri- ate SNA access routines. For additional information about which ac- cess routines are supported, see the Optional Software section of this Software Product Description. Compaq SNA Server for OpenVMS Alpha 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 o Closed User Groups o Reverse Charging Management Utilities 2 The Compaq SNA Server for OpenVMS Alpha provides the management util- ities SNANCP and SNAEVL. SNANCP is used to manage and monitor SNA server components 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 Alpha, 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 attempts to diagnose the cause of the failure. INSTALLATION Installation Services from Compaq are recommended for a customer's first purchase of this software product. These services provide for instal- lation of the software by an experienced software specialist. 3 HARDWARE REQUIREMENTS Processors Supported The Compaq SNA Server for OpenVMS Alpha supports a maximum of 255 ses- sions via local user connections and DECnet connections.
