The following stack trace will be observed if you encounter this issue: sqlno_cost_ridbid_iscan sqlno_cost_iscan sqlno_prop_iscan sqlno_reeval_cost sqlno_smp_reeval_props sqlnoSmpPropagateCosts ... The problem will only occur if all of the following conditions are satisfied: 1. The database partitioning feature (DPF) is used 2. Intra-partition parallelism is enabled (INTRA_PARALLEL is set to YES) and the query degree is > 1 or set to ANY 3. The statement references a table with one or more partitioned indexes 4. The optimizer chose an access plan with an index access of apartitioned index 5. A subquery predicate is applicable at the index access | |
