Problem IC63758
|
Status: Closed |
DB2 SERVER MAY ABEND DURING QUERY COMPILATION OF STATEMENTS WITH PARTITIONED INDEXES IN A DPF ENVIRONMENT WITH INTRA_PARALLEL ON |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
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 |
