DB2 - Problembeschreibung

Problem IC75593 Status: Geschlossen

DB2 DESIGN ADVISOR (db2advis) MAY NOT PROVIDE CONSISTENT RECOMMENDATIONS
FOR THE SAME WORKLOAD

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
The DB2 Design Advisor (db2advis) may not provide consistent 
recommendations for the same workload on multiple runs. 
 
That is, when the exact same options or command-line parameters 
and values are supplied to db2advis at 2 separate invocations, 
and the exact same input workload is used, one invocation may 
give different recommendations than the other. 
 
This can occur if the input workload for db2advis is small and 
the total number of recommendation candidates generated is also 
small. The candidates can be of all types, i.e., 
index, MQT (Materialized Query Table), MDC (Multi-dimensional 
Clustering) and DPF (Data Partitioning Feature).
