DB2 Health Monitor-Monitor Heap Utilization

12 January,2010 by Tom Collins

On a production system running DB29.5 on Red Hat Linux 4.6 .
If you want to keep the health monitor running, you can  increase
the size of MON_HEAP_SZ to about 2048. But I decided to turn the Health
Monitors Off, due to overconsumption of memory.
These are OLTP databases. Since I've turned off the health monitor the system is running smoothly

DM10500E Health indicator "Monitor Heap Utilization"
 ("db2.mon_heap_util") breached the "upper" alarm
threshold of"95 %"
 with value "150%" on "instance" "db2instp".
 393216) * 100)"= "150 %". History (Timestamp, Value,
Formula): "
 (16/11/200912:03:30.820296, 83, ((327680 / 393216) * 100))"


db2 update dbm cfg using HEALTH_MON OFF
db2stop and db2start to restart the instance.
