Rajesh,
We are not loading any data. There are only two steps present:
1. Create tables – 1127
2. Create indexes – approximately 7000
The CPU spikes immediately when the tables are being created.
Regards,
Deb

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 ?
