RUNNING DB2ADVIS TO RECOMMEND DPF PARTITIONS CAN CAUSE DB2 INSTANCE TO TRAP |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
Running db2advis to recommend DPF partitions can cause DB2
instance to trap if the SQL statements that are passed into
db2advis meet all of the following conditions:
1) A table is NULL-producing side of an outer join
2) At least one of the partitioning columns of the table is
bound to a constant, or is bound to a column in the outer SQL
block (i.e. outer reference), via an equality predicate, or via
transitivity of multiple equality predicates.
A similar trap stack will look like the folllowing:
sqlno_part_scale_index
sqlno_cost_ridbid_iscan
sqlno_cost_iscan
sqlno_prop_iscan
sqlno_index_scan
sqlno_crule_index_scan
sqlno_crule_access_root
sqlno_crule_access
sqlno_plan_qun |
