THE MON_GET_LOCKS TABLE FUNCTION SOMETIMES REPORTS CACHED, UNUSED LOCK STRUCTURES | |

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 -------------------------------- --------- 01000000010000000100A06156 S 41414141415A425A7F4760B841 S 434F4E544F4B4E3128DD630641 S 02000400000000000000000054 N FAFF0080000000000000080054 N FAFF0080000000000000070054 N FAFF0080000000000000060054 N | |
