Dear Deb,
i feel three distinct steps are present
1. CREATE TABLE
2. LOAding of data in tables
3. Creation of indexes
It is still not clear when you are seeing your system becoming unresponsive to
other application. Is it during loading of data or creation of indexes?
1. can you give any idea about how much data you are loading ? rows count or GB data etc
2. how many indexes are you creation ?
