exp-imp functions vs dblink

edited Nov 28, 2014 10:02AM in Database Utilities (MOSC) 8 commentsAnswered

hello all...

I have to migrate a huge number of data from one DB to another.

Using the exp+imp comands, the file xxx.dmp is very large ... about 1.2 GB, and it takes about 3+4 (exp + imp) hours to transfer the data.

The question is ... if I use a dblink instead, from the source DB to the destination DB ... may it improve the transfer time?

What is better ... using exp+imp comands or DBlink to transfer a huge amount of data? Any suggestion?

thank you
