Problem IC90679
|
Status: Closed |
MQT NOT CONSIDERED FOR REWRITE MATCHING IN INSENSITIVE SCROLLABLE CURSOR QUERIES |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
MQTs are not considered for rewrite matching in insensitive
scrollable cursor queries. This may result in missed
opportunities in performance optimization.
NOTE: Retrieving result set of queries using scrollable cursors
has performance overhead. Even with MQT routing, performance
may not be as good as non-scrollable cursors queries.
Scrollable cursors should be used only when required. |
