Poor performance afther migration the database of an 11.5.10.2 from 9.2.0.7 to 10.2.0.4
We have some performance problems afther upgrade database to 9.2.0.7.
Server AIX 5.3 8Gb. Memory
With 9i work perfectly, good performance, afther upgrade using standar procedure and applying standar parameters from notes.
We have:
- Standart go slower.
- Customizations are really problems of performance.
Is normal poor performance in 10gR2 that in 9i?
