Problem IC75149
|
Status: Closed |
DB2 DESIGN ADVISOR (db2advis) MAY NOT PROVIDE CONSISTENT RECOMMENDATIONS FOR THE SAME WORKLOAD |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
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). |
