APAR status

  • Closed as program error.

Error description

  • Alert shows:
    
    ADM10500E Health indicator "Monitor Heap Utilization"
    ("db2.mon_heap_util") breached the
    "upper" alarm threshold of "XX %" with value "XXX %" on
    "instance" "DB2". Calculation:
    
    Health Monitor is sending Alert to db2 user while Monitor Heap
    is set to Automatic. This APAR will fix the code in such a way
    that
    the health monitor code , by default will not monitor these
    health indicators. For those users who don't have the
    MON_HEAP_SZ
    to 'AUTOMATIC' and they want these health indicator alarms, they
    can enable using   "update alert cfg "  command.
    

Local fix

  • You can turn off the Monitor Alert switch by doing following:
    
    db2 update alert cfg for database manager using
    db2.mon_heap_util  set  THRESHOLDSCHECKED  NO
    db2 update alert cfg for databases using db.db_heap_util  set
    THRESHOLDSCHECKED  NO
