buffer parameter in export and import

Hi Vitaliy

While exporting and importing tables, i have read that buffer parameter plays a 
very important role and should be sized accordingly. But how do we calculate 
which value is suitable for this

SWathi,

You'll know when you need to set the buffer to a higher value because the 
import will fail with small buffer.  For example it can happen when importing 
large tables (multiple partitions, etc..).  Don't worry too much about it -- 
you'll know when you need to size it larger.  It's a trial and error thing.  
I've used buffer=12582912 with good results (on import).
