APAR status
Closed as program error.
Error description
You are running Informix with OPTCOMPIND set to 2. You noticed that a simple query against a fragmented table takes more time if PDQ is enabled. You checked the query plans and found that the Informix optimizer assigns lower cost to a plan with sequential scan (PDQ enabled) while the plan used without PDQ uses index path, takes less time but costs more.
