10G is a turning point, it includes some many great features. One of these is Oracle Data Pump. Data pump is the replacement for the EXP and IMP tools, that many of us know so well. With 10G however, you will still find EXP and IMP, however they are going to leave us soon. Instead you have to look closer to EXPDP and IMPDP.
Ok you might ask, so whats new about Oracle Data Pump ? Well for starters, you will be able to query the Oracle database using the Data Dictionary views, on job status, for your imp and exp jobs. A job can also be restarted from where it stopped. Thats right ! Data Pump keeps a log, like the redo log, to paint a picture. If a job goes down, for some reason - you just restart it from where it stopped, no need to start from the beginning again.

DBMS_DATAPUMP.
