HP SNA Server for OpenVMS Alpha

HP SNA Server SPD 70.89.04
for OpenVMS Alpha, Version 1.3
HP SNA Server also supports the following optional fa-
cilities for QLLC circuits:
• Flow Control Negotiation
• Closed User Groups
• Reverse Charging
Management Utilities
The HP SNA Server for OpenVMS Alpha provides the
management utilities 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 HP
System Manager 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 informa-
tion 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 HP SNA node should be viewed
as part of the HP environment; the management of the
line connecting the OpenVMS Alpha system to the IBM
system is a joint responsibility of the IBM and HP 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 application 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 action.
The Installation Verification Procedure (IVP) for the
HP SNA Server for OpenVMS Alpha V8.2 and V8.3,
SNAVMS$IVP, is also useful for problem isolation.
SNAVMS$IVP is run separately from any access rou-
tine, and can be used to verify connectivity to specific
IBM applications over speci fic 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 HP are recommended for
a customer’s first purchase of this software product.
These services provide for installation of the software
by an experienced software specialist.
HARDWARE REQUIREMENTS
Processors Supported
The HP SNA Server for OpenVMS Alpha supports a
maximum of 255 sessions via local user connections
and DECnet connections. Restrictions are based on
processor memory, line speeds, and CPU. For informa-
tion about supported processors, refer to the OpenVMS
Operating System for Alpha Software Product Descrip-
tion (SPD 25.01.xx).
Users can configure their IBM line to activate up to 255
logical units (LUs) per PU. See the release notes for
recommended concurrent session requirements.
Minimum Recommended Configuration
A minimum hardware system configuration includes:
• One system disk
• A load device (CD-ROM)
• 64 MB memory
• Modems or modem eliminators
• A supported synchronous device as described in the
HP X.25 for OpenVMS Alpha Software Product De-
scription (SPD 417.37.xx)
Disk Space Requirements (Block Cluster Size = 1)
Disk space required for installation: 8000 blocks
Disk space required for use
(permanent):
6500 blocks
These counts refer to the disk space required on the
system disk. The sizes are approximate; actual sizes
may vary depending on the user’s system environment,
configuration, and software options.
