Hi gurus,
I have migrated from 8i to 9i. There is a query which was quite faster in
8i (1sec) but it became slow in 9i (1 min).
I ran the explain plan. The position value is as follows
in 8i Cost =1846
in 9i Cost = 93241102
pls suggest how to fix this issue
Both have optimizzer_mode set to "choose".
