What do you mean "assigning the big rollback segment?" How do you do
that to an export
If an expert is done with consistent = 'N' it still must preserve some information.
In the beginning export runs some selects against the data dictionary and needs that
data to be consistent throughout the export. If that data changes then it needs to be
reconstructed from the undo generate

The idea of huge rollback segment is just to eliminate the contention the

that to an export and what does it accomplish?
What does COMMIT=Y
Would you post the parameter file ??
Huge Buffer, commit=y, direct=y, assigning the big rollback segment should
help you to have faster export ,
and also you can have a look at the DISK I/O stats ( verify the OFA is same
on both the boxes ).

Hi guys,
I moved my database from Solaris 7 to Solaris 8 box (Sun Fire 4800, faster processors
