Differences Between NS 3000/V and NS 3000/iX The following paragraphs summarize differences between NS 3000/V and NS 3000/iX. Make sure that you account for these differences that could affect your network when migrating to NS 3000/iX. For information on operating system migration, refer to the MPE/iX Migration series. Some NS 3000/V hardware components are not part of an NS 3000/iX network, such as the ATP for terminal connections, and the INP for network links. On an NS 3000/iX network, the DTC provides connections for local or remote terminals and serial printers. The DTC also provides MPE/iX access to X.25 through a DTC/X.25 Network Access card. The Datacommunications and Terminal Subsystem (DTS) LANIC on the MPE/iX host is used for system-to-system X.25 connectivity. Before migrating your network, identify any unsupported network connections. The network connections that are not supported on NS 3000/iX networks are as follows:
On NS 3000/V networks, the SYSDUMP program is used to perform I/O configuration which includes configuring terminals, printers, and other I/O devices and drivers. On NS 3000/iX, terminals and serial printers are configured on the host (using NMMGR) and on the OpenView Windows Workstation (using the OpenView DTC Manager software). For more information on configuration using your OpenView Windows Workstation, read Using the OpenView DTC Manager. 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). 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. 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:
