I have used the following to do an export. The export uncompressed is >390 MEG and compressed it is 113 MEG. It creates a pipe file, the compressed file, and the nohup.out file.
/etc/mknod ora_export.dmp p
nohup compress < ora_export.dmp > ora_export.dmp.Z &
nohup exp id/pswd constraints=y grants=y full=y file=ora_export.dmp &
The following will show the contents of the compressed export file:
/etc/mknod ora_export.dmp p
nohup uncompress < ora_export.dmp.Z > ora_export.dmp &
nohup imp id/psw show=y full=y file=ora_export.dmp &
I did not see a big difference in the time to export. Received on Tue Nov 08 1994 - 18:30:56 CET
