| allocated memory (HAN) |
The pool of memory reserved by the SAP HANA database across its different processes before actual use.
This pool of memory is preallocated from the operating system over time, up to a predefined global allocation limit, and is then efficiently used as needed by the SAP HANA database code. More memory is allocated to the pool as memory consumption increases. If the amount of memory used nears the global allocation limit, the SAP HANA database may run out of memory if it cannot free memory.
