DB2 FOR LUW / DB2FORLUW / 950 - DB2 | |
Problem description: | |
Suppose a database event monitor is created. After some SQL activity a flush is done on the event monitor followed by a connect reset. The flush and reset cause TWO events to be written, one generated by the flush and the second one generated by the connect reset. There is a count which seems wrong for the event that is written due to the connect reset. 4) Database Event Record is the result of a flush: FALSE Lock Statistics: Lock Waits: 0 Total time waited on locks (milliseconds): 0 Deadlocks: 0 Lock escalations: 0 X lock escalations: 0 Lock timeouts: 0 ................................................................ ...... Catalog Cache Statistics Catalog Cache Lookups: 22 <---- this is wrong Catalog Cache Inserts: 2 Catalog Cache Overflows: 0 Catalog cache high water mark: 86560 Catalog cache statistics size: 18446744073709551604 <---- this is wrong | |
