INCORRECT STATEMENT INFORMATION REPORTED IN APPLICATION SNAPSHOT ACCOMPANIED BY INCREASING MONITOR HEAP CONSUMPTION AND SQL PERF | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
An application repeatedly executing a routine within the same UOW may experience incorrect application snapshot information, memory growth in monitor heap, and performance degradation. In order for this problem to occur, the following conditions must be satisfied: - Statement monitoring is on - The application calls a UDF or routine repeatedly within the same UOW and the routine issues SQL statements - The symptoms are likely to be more pronounced if MON_HEAP_SZ is set to AUTOMATIC or a large fixed value Application snapshots will contain increasing numbers of repeated statement elements with the same package/section/cursor information. Increasing growth of memory allocations from the monitor heap may also be observed, and SQL statements executed by the application may experience gradual performance degradation. | |
