Hi there,

For my tuning practice here the response time is critical. I just want to know which init parameters are more helpful for me in this regard.

FYI:

optimizer_dynamic_sampling integer 1
optimizer_features_enable string 10.2.0.3
optimizer_index_caching integer 0
optimizer_index_cost_adj integer 8
optimizer_mode string ALL_ROWS
optimizer_secure_view_merging boolean TRUE


thanks,
A

10 steps to tuning (old Oracle doc):
Step 1: Tune the Business Rules
Step 2: Tune the Data Design
Step 3: Tune the Application Design
Step 4: Tune the Logical Structure of the Database
Step 5: Tune Database Operations
Step 6: Tune the Access Paths
Step 7: Tune Memory Allocation
Step 8: Tune I/O and Physical Structure
Step 9: Tune Resource Contention
Step 10: Tune the Underlying Platform(s)

Instance parameters come in steps 6 to 9.
Did you already make the previous steps?

Regards
Michel
