Re: ORacleDb
First of all check your memory, if there is any bottleneck in memory and system is utilizing it heavily then you need to increase the memory.
Check with these commands.
#swapinfo -tam
#vmstat
#sar -d 5 5

This isn't an English and it isn't a SI unit prefix:

Collect some data.
Before making decisions, check utilization. You may be able to improve performance with some kernel adjustments or reducing demand in the oracle SGA configuration.

Re: ORacleDb
But being that the query is fetching 1 crore rows, you need to probably work more with query first:
YOu need to check if you have indexers defined and you can perform an explain plan for the query to find out the query execution cost and time.
