Hi all,

i have to take export of a large schema which contains 64GB data.
The problem is i have 30GB on one mount point say /u01 and 10 GB on another mount point.
I can use FILESIZE parameter to make multiple dump files.
But is there any other way ?
i have to set crontab to make backup on alternate days.Also suggest me the fast method.

You can copy tablespace specific data by transport_tablespaces feature which is fast with restrictions.

You can compress through a pipe at the same time you export then you don't need so much space.
Something like:

mknod exp.pipe p
gzip < exp.pipe > scott.exp.gz &
exp userid=scott/tiger file=exp.pipe

Michel

No but you can split the output file.
Something like (beware! not tested):

mknod exp.pipe p
(gzip < exp.pipe | split -b 2048m - scott.dmp.gz.) &
exp userid=scott/tiger file=exp.pipe

Regards
Michel
