DB2 FOR LUW / DB2FORLUW / 970 - DB2

In a Data Partitioning Feature (DPF) enabled database, users 
have the option of replicating their tables in a partition 
group. 
 
For a query referencing a Base Table (BT) that has 1 or more 
dependent Replicated Table(s) (RT), the Optimizer decides on the 
usage of any RT(s) in the final access plan based on costing. 
 
Users wishing to enforce usage of RTs, regardless of the 
Optimizer's costing decisions, may do so with a registry 
variable (REGVAR), which can be specified as follows: 
 
db2set DB2_EXTENDED_OPTIMIZATION=FORCE_REPLICATED_MQT_MERGE 
 
Other values for the DB2_EXTENDED_OPTIMIZATION REGVAR can be 
combined with this one by separating them with commas. 
 
Note that with the REGVAR set, if there are multiple dependent 
RTs or Materialized Query Tables (MQT) for a BT, the first found 
RT will be used and all other dependent objects ignored.
