Status: Geschlossen |
INVALID CATALOG CACHE STATISTICS SIZE SHOWING UP IN SOME DATABASE EVENT MONITOR RECORDS |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
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

| Local-Fix: |
Use db2pd -db testdb -statisticscache summary or
db2pd -db testdb -catalogcache or look at other event records
to get accurate information on the statistics and catalog
caches. |
