Statement Memory Limit in SAP HANA

The parameter is called "Statement_memory_limit". This parameter will help ensure a single user’s statement does not cause “Out of Memory” scenarios on the HANA appliance. A system wide “Statement_memory_limit” was introduced with HANA SP8

When reaching the statement memory limit, a dump file is created with "compositelimit_oom" in the name. The statement is aborted, but otherwise the system is not affected. The unit of measure is GB.

Default : 0 (no limit)

Set system level Statement memory limit

a. Login into HANA Studio and navigate to the “Configuration” tab.
b. Open "Global.ini–>memorymanager"
c. Set "statement_memory_limit" = desired limit in MB’s


1> This limit will be system specific depending on the Global Allocation Limit, if the system limit has never been set and the goal is to only enable user specific limits set the limit to a very high percentage of the Global allocation limit. For example if global allocation limit is set to 234496 MB, set the Statement_memory_limit to 200000 MB. The system limit will never be met and basically ignored.



2> The system limit HAS to be set to enable USER limits.
3> Note setting the "Statement_memory_limit_threshold" instead or in addition to the "statement_memory_limit" will DISABLE the USER limit. This has not been determined if a bug with Rev 91 or SAP design.
