The Question is:
When I transfer a certain indexed binary data files from an alpha server to a
local hard drive on my PC (running Win 2k professional with NTFS formatted
hard drive) via a binary FTP over our network, then transfer the file back to
the alpha by the same me
thod, the structure of the file is changed and it is no longer usable by the
application that created it. Specifically, the file is listed by the DIR /
FULL command as being indexed and a fixed record length of 6089 bytes before
the FTP transfer, and aft
er the FTP, DIR / FULL reports the exact same file size, but it is now
sequential (no longer indexed) and has a fixed record length of 512 bytes.
How can I transfer these files without changing their structure?
The Answer is :
Please see the OpenVMS FAQ discussion of corrupted BACKUP savesets for
related information -- systems not using OpenVMS and the OpenVMS file
system can and often do effectively corrupt certain OpenVMS file formats.
Even sequential file formats, for instance, are not necessarily entirely
compatible at the data (record) level.
You will want to use the Freeware zip tool, the Freeware bzip tool, the
Freeware tar tool, or the OpenVMS BACKUP utility or some other similar
file-encapsulation tools to preserve the OpenVMS RMS file attributes for
those OpenVMS RMS files that must be transfered through foreign file
systems.
