Performance improvement required using sql loader

KunwarFeb 1 2014 — edited Feb 10 2014

Hi Friends.

I want to improve the speed of my data load activity using sql loader.

Details:

My current configuration "rows=4000000 bindsize=20480000 direct=y" .

Total rows to be inserted = approx. 50M

Scenario:

My table is range partitioned  using "interval (numtodsinterval(1,'day')) "and each partition is loaded daily with data worth over 2GB of data.

This import takes about 3-4 hours. I don't drop the only index ( local partitioned) on this table ( oracle creates the index after the direct load itself).

Can you please suggest me a faster approach with below details:

1. I can't drop the index ( It is of size 90GB) because i have to do this activity daily.

2. This data load activity happens daily and the whole is needed by other team members for analysis purposes.

My objective : to reduce the data load time as this everyone has to wait for this data load to complete for analysis.
