Using NS3000/iX Network Services (36920-90008)

218 Appendix A
Migration From NS 3000/V to NS 3000/iX Network Services
Differences Between NS 3000/V and NS 3000/iX
Differences Between NS 3000/V and
NS 3000/iX
NS 3000/iX is a compatible subset of NS 3000/V, the powerful
networking software available on the MPE V/E based members of the
HP 3000 family.
Special Note on
Terminal Echo
When communicating between an MPE/iX based node an MPE V based
node, if echo ever gets turned off, proceed as follows:
1. Issue a colon (:) to return to your local node.
2. Restore the echo on your local system according to the method for
that node (the method is different depending on whether your
physical terminal is connected to an MPE V based node or an
MPE/iX based node). Remember: the node that your physical
terminal is connected to always determines how you restore your
terminal’s echo.
3. Note that this procedure restores echo on the local system. To ensure
that echo is also restored on the remote system, you may wish to run
a program that issues an FCONTROL 12 on the remote system.
Missing Features
The following list specifies the features that were available in
NS 3000/V but are not available in NS 3000/iX:
Program-to-Program communication (PTOP) is not available. For
information on translating your PTOP applications so that they can
run on an MPE/iX based machine, please refer to the “Conversion
Checklist” section.
No-wait I/O Remote File Access is not available.
Changed Features
The features that changed from NS 3000/V to NS 3000/iX are as
follows:
When using Network File Transfer (NFT) or Remote File Access
(RFA) in NS 3000/iX, only files with MPE V characteristics are
supported. For instance, the mapped access file system feature of
MPE/iX is not supported by NFT and RFA in NS 3000/iX.
Remote Data Base Access in NS 3000/iX is supported only for
TurboIMAGE databases. Remember that an IMAGE database on a
DS/3000 node can be accessed by using an intermediate NS 3000/V
node. The SHOWCOM command has been replaced by the
LINKCONTROL STATUS command.
