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

Т.е. можно на эту ошибку не обращать внимание, а еще лучще отключить монитор?

да, dbheap у нас automatic
У нас все параметры, отвечающие за память в automatic, кроме instance_memory
