We have poorly performing queries on custom applets. Is there any way to override the Optimizer_mode=FIRST_ROWS_10 setting in the data connector or to ensure the *all row* hint described in TechNote 582 is used?
The queries work well thru an sql client but poorly from within Siebel. Setting ALTER SESSION SET OPTIMIZER_MODE = FIRST_ROWS_10 within the sql client replicates the poor performance seen within Siebel.
