Problem IT04787
|
Status: Closed |
DYNAMIC STATEMENT NOT FOUND IN STATEMENT CACHE AND RECOMPILED UNNECESSARILY RESULTING IN POOR RUN TIME PERFORMANCE |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
Under certain circumstances a dynamic SQL statement may be
re-compiled even though there exists a matching entry in the
statement cache. This may happen if all the following are true:
1. The SQL statement references one or more inlined SQL function
2. The inlined SQL function also references one or more inlined
SQL functions, i.e. nested inlined SQL functions
3. The user invoking the SQL statement does not hold DATAACCESS
authority
4. The user invoking the SQL statement does not hold EXECUTE
privilege on one or more of the nested inlined SQL functions
Even if all the above are true, the complexity of the SQL
statement determines if the problem occurs. |
