I have a customer having intermitten problem of seeing file dates
changed when she copied files from the network drive one folder to
another folder in the same network drive.
She has seen this on PATHWORKS 4.1/WIN311 clients and NT4.0 - SP2
client. Our server is PW50D-ECO3. I have observed this happen on her
machine, but have no luck recreating the problem easily. Is there an
explanation to this?
Having long discussion with the CSC support, one possible solution is
to provide a FAT volume for her. With no explanation to this problem
and no easy way to reproduct the problem, I am not sure whether it is
an overkill to her problem. I was hoping an explanation first, discuss
it with this customer second, then if needs to go for whatever the fix
needed for the date problem.
Thanks,

A created file gets entered in the cache. Only when the
file is actually closed, the file header is updated.
Are you seeing this maybe ?? We have the OFC which can
hold off any closures.

We've noticed sometimes during the copy, the file dates are changed for
a short period and after the copy is completed, the dates are switched
back to the original. This could be what you are saying the cache that
we are seeing at the destination location that sometimes shows the dates
changed and then updated to the original dates after the copy is done?

The one that I observed a group of files copied and dates changed and
stayed changed for at least 10-15 minutes when I was there. The dates
never changed back. Something happened to these files??
What is OFC? Sorry please explain.
Thanks a lot,

OFC = Open File Cache.
When a file close request is issued, the file not NOT
closed immediately but delayed for OFC_INTERVAL (5 sec's).
If within that timeframe the file is opened again (by the
same PC) then the file actually remains open. Only when the
file is not touched then the OFC expires and the file is
closed on VMS level.

| 4266.4 | Is timing a possibility? | JULIET::HUNG_YU | Yuh-Juan Hung@WRO | Wed Apr 23 1997 09:47 | 15 |
I am assuming the OFC is at VMS level, because we turn off the Open
File Caching on the PATHWORKS cluster.
How about these file dates changed and stay changed? She is the only
user who can access that network drive, so during the copy there will
not be anybody touching the files. When the file is finally closed,
the dates should be (in theory) changed back to the original.
Since the network connection from her building is not perfect
(sometimes they have network problems from that building connecting to
the host.), would it be possible that those files did not get closed
after the OFC_INTERVAL expires? I am in a different building.
Thanks,
