MPE/V to MPE/iX Migration
Differences Between NS 3000/V and NS 3000/iX
Differences Between NS 3000/V and NS 3000/iX
There are a number of differences between the way NS is implemented on MPE V systems and the way it is implemented on MPE/iX systems. These differences affect the network itself, some of the applications that users may run over the network, and the command used to obtain status information about the network. Since it is helpful to understand these differences as you prepare to move an existing MPE V network to MPE/iX, they are summarized below.
Network
A number of the methods available for making connections to an MPE V network are not available with NS 3000/iX. If your MPE V network includes one of these you will need to modify your network configuration before attempting to use the network on MPE/iX systems. More information on the specific steps required to modify or remove unsupported links or connections can be found later in this appendix.
The connection methods that are not supported on NS 3000/iX are:
•Manual dial modems.
•Asynchronous Network Link.
•Bisynchronous
In addition, while it is possible to access a DS/3000 node directly from an NS 3000/V node, this capability is not supported on NS 3000/iX. A user of an NS 3000/iX network who wants to access a DS/3000 node must first access an MPE V NS node. This is because the DS/3000 code that was included as a subset of the NS 3000/V code is not provided with NS 3000/iX.
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
