- Looks like you are UNIX by your address, so here goes
- (1) Compressing export to disk
- mknod ora_export.dmp p
- nohup compress < ora_export.dmp > ora_export.dmp.Z &
- exp / ...... file=ora_export.dmp
-
- This lets you compress on the fly without using any disk (well,
- you will use 4 disk blocks or the size of a pipe).
-
- (2) If exabyte takes streaming input could do the following
- change nohup line to not write to ora_export.dmp.Z but use
- dd(1) {sourcing from stdin} and output to tape.
-
- Hope this helps
