If you find a good answer please let me know! I believe Windows does have a
pipe mechanism but it isn't exposed to the OS, so mknod is unimplemented in
cygwin.
The obvious approach is to just export and then compress in two steps. When
short of disk space we have done this via a crossover cable to another Windows
box. Another thing to try might be to use the FILESIZE switch in exp, and then
gzip each individual "sub-file" in turn (from another session) as soon as exp
stops writing to it. You can then write a nice script on Solaris to untaggle
this.

Hi friends:
We have to migrate a database on windows 2000 to Solaris, and to
another location. So we want to reduce the size of the dump file via
gzip.
As windows does not support pipe like we do in unix: mknod exp.pipe
p; gzip <exp.pipe >dmp.gz & and run exp. I tried cygwin. But seems
gzip simply do not do anything there. Anyone tried using pipe on
windows/cygwin? Or is there similar workaround?
