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? -- Regards Zhu Chao www.cnoug.org -- //www.freelists.org/webpage/oracle-l
