Increasing db_block_buffers will almost certainly make no difference to the performance of the query you've shown us.

Manipulation of hash_area_size might change your query's execution plan, but I can't tell you whether for better or for worse. But it is important to understand that changing hash_area_size might profoundly change a lot of other execution plans in your system as well. Some for better, and--I'm sure--some for worse.

Your log buffer size is very likely an irrelevance with respect to your query performance.

Hi Again,

Another question is, if i increase the following parameter is there any negative effective or not?

1. db_block_buffers = 10000 change to 20000
2. hash_area_size = 2048000 change to 51200000 5 M
3. log_buffer = 262144 change to 5242880 5 M

Thanks
