TSM crashed this morning during non-peak hours. I noticed that DB2 was using roughly 77% of the physical memory on our TSM server. The server has 30GB of memory installed.
I checked DB2 and saw that there was an active alarm:
Monitor Heap Utilization 255%
This indicator tracks the consumption of the monitor heap memory, based
on the memory pool with the ID SQLM_HEAP_MONITOR. The utilization is
calculated using the formula (db2.pool_cur_size / db2.pool_max_size) * 100
for the Memory Pool Identifier SQLM_HEAP_MONITOR. Once this percentage
reaches the maximum, 100%, monitor operations may fail.
Has anyone else run into this issue with DB2? We are at version 9.7.2 and TSM is at version 6.2.2.
