NS X.25 Migration: NS 3000/V to NS 3000/iX
Differences Between NS 3000/V and NS 3000/iX
PAD devices on NS 3000/V are configured (using NMMGR) as part of
the X.25 network configuration. On NS 3000/iX when PC-based
network management is used, PAD devices are configured both on the
host (using NMMGR) and on the OpenView Windows Workstation
(using the OpenView DTC Manager software).
Configuration Files
NS 3000/V network configuration files are separated into two files, the
NMCONFIG file, which contains link information, and the NSCONF file,
which contains the transport configuration and other subsystems you
have purchased such as SNA.
NS 3000/iX systems have a single NMCONFIG.PUB.SYS file that contains
information for the network transport, for NetIPC and link-level
logging, and also for the Datacommunications and Terminal Subsystem
(DTS). NMCONFIG.PUB.SYS also contains information for any other
subsystems you have purchased such as SNA.
Network Services
Differences in the support of network services between NS 3000/V and
NS 3000/iX can affect applications that users may currently be running
on the NS 3000/V network. These differences are:
• NS 3000/iX supports PTOP for HPDESK only. Network users who
are running PTOP programs will need to convert them to
NetIPC/RPM programs before running them on an NS 3000/iX
network. Refer to the NetIPC 3000/XL Programmer’s Reference
Manual and the Using NS 3000/iX Network Services for more
information.
• Nowait I/O RFA is not available with NS 3000/iX. Privileged mode
programs that use nowait I/O Remote File Access over an NS 3000/V
network will need to be modified before they can be run on an
NS 3000/iX network. Refer to Using NS 3000/iX Network Services
for more information.
Obtaining Device Status Information
On MPE V systems, the SHOWCOM command returns status information
about communication devices such as Local Area Network Interface
Controllers (LANICs). On NS 3000/iX systems, this information is
available with the LINKCONTROL...;STATUS command.
