Status: Geschlossen |
THE MON_GET_LOCKS TABLE FUNCTION SOMETIMES REPORTS CACHED, UNUSED LOCK STRUCTURES |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 980 - DB2 |
| Problembeschreibung: |
The MON_GET_LOCKS table function sometimes reports cached,
unused lock structures. This seems to only happen when the
LOCKLIST is sufficiently high.
Looking at the output of the MON_GET_LOCKS table function, the
records showing LOCK_MODE='N' are the cached lock structures
which should not be reported.
$ db2 +c "SELECT LOCK_NAME,LOCK_MODE FROM TABLE (MON_GET_LOCKS(
NULL, -2))"
LOCK_NAME LOCK_MODE
