MPE/V to MPE/iX Migration
Differences Between NS 3000/V and NS 3000/iX
Applications Support
There are also differences in the implementations of NS 3000/V and
NS 3000/iX that will affect certain applications that users may
currently be running on your MPE V network. These differences are as
follows:
• NS 3000/iX supports PTOP for HPDESK only.
On NS 3000/iX PTOP is not supported for applications other than
HPDESK. Network users who are running PTOP programs will
need to convert them to NetIPC/RPM or BSD 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 MPE V network will need to be modified before they can be
run on an NS 3000/iX network. Refer to the Using NS 3000/iX
Network Services for more information.
Obtaining Status Information
On MPE V systems the SHOWCOM command returns status information
about a communication device, and is used to determine line activity
and quality. This information is still available on NS 3000/iX, but is
accessed through a different command. Use the LINKCONTROL STATUS
command to access status information on NS 3000/iX.
