 Memory used - what is "Other memory"? Very interesting for me [...] Lock Manager Heap is of size 16809984 bytes Database Heap is of size 9273344 bytes Database Monitor Heap is of size 5226496 bytes Other Memory is of size 729202688 bytes FCMBP Heap is of size 4997120 bytes Total: 1889337344 bytes "Other memory" size 40%(!!!). How resolve this memory leak? Andy      |

| Re: Memory used - what is "Other memory"? Yes, we have appgroup_mem_sz=30000 *4K = 120 Mb max, is't correct? Inside snapshot I see Application Group Shared Heap is of size 99631104 bytes and this memory ~98Mb calculated in result string. But other memory size - 730Mb! Andy 2IBM: ??? |

The value is 'correct' depending upon how many applications you have connected to the database, the value is configured in conjunction with GROUPHEAP_RATIO and APP_CTL_HEAP_SZ. What these values do is control how many applications can 'fit' into one memory group, once one memory group is 'filled up', another memory group is allocated, hence you have lots of memory allocated if your groups are configured too small. |

| Re: Memory used - what is "Other memory"? Haven't been completly following this, but is the database memory set to automatic? If so it will allocate more then what is configured and this might be the "Other Memory" you are seeing.
