Hi,
I have been watching the thread about the file::copy. I ran into an
issue in the Linux environment that brings a serious question, MAX file
size. Keep in mind the server is running 7.0 RH, we have 7.2 Enterprise
Server also, and we pay for support. But even the RH support says they
can't handle files in excess of 2GB (approx).

i believe RH 7.1 beta r1 (code name Fisher) which uses kernel 2.4.0 is the
first RH that supports the LFS (Large File Support) extension. your server
running 7.0 won't be able to address > 2GB file. If you have 7.2
Enterprise, why don't you use that instead? If you pay for support, isn't
RH suppose to provide help / instruction on how to get your 7.0 with LFS
support?
if you simply want to know if Perl is able to deal with > 2GB file, you can:
[panda]$ perl -V | grep 'uselargefiles'
and you should see something like:
uselargefiles=define
to see that if perl (the binary) is compiled to use LFS API, use:
[panda]$ perl -V | grep 'OFFSET_BIT'
and if you see something like:
D_GNU_SOURCE -fno-strict-aliasing -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
you are in good shape. the easiest solution to get LFS support is to upgrade
your 7.0 imo.

Thanks for the observations. But the point that RH made to me (Again,
about 6 months ago) was that this issue was in 7.0-7.2 and YES, they did
not recommend rebuilding the kernel because at THAT time the 2.4 was
"Buggy" in their opinion. I am not so worried about Perl being able to
READ/WRITE or what ever for large files, but the O/S has to be able to
do this first, correct? That's my main point and the obstacles I've run
into on this. It seems like to me, it is time to revisit this with the
RH folks to see what THEY say about it, then go through the pain of
upgrading a server with a ton of perl code on it, of course, everything
must be TESTED to make 100% sure I haven't dropped anything through the
cracks.
Thankx...
