That's is pretty big, my personal experience with big files on udt was up to
about 60Gig - we did use memresize no problems
Hi,
That will work, I have done that many times.
Just make sure you check the permissions at unix level after the copy.

I have a very large file that I don't have enough free space to memresize,
however howabout I create new dynamic (temporary) file and then copy all the
records (in
We've recently added a new UniData tuneable to udtconfig UDT_SPLIT_POLICY
which can help conserve space when an overflowed dynamic file splits. The total
size of the contents are not necessarily the same as the physical file size.
Always worth checking with guide and the latest fixes and

I resize most of my Dynamic files this way. I don't like having a small
overxxx segment for every datxxx segment that memresize creates.. By creating
the new file my self, I don't have a lot of these small overxxx segments that
are never used.
I also wrote a process to Select the old file and

Yes, absolutely - I'm a great believer in a minimum modulo. If I have to copy
large files from one to another my preferred method is to drive a load of
PHANTOMs with save-lists in parallel. Also useful to drive from a SELECT not a
SSELECT so you get a file-sequential order by chunking the input
