SAP HANA – How often are OOM dumps written?

By default OOM dump is written once in 24 hours.If multiple OOM errors happen only the first occurrence of the OOM error will generate an OOM dump, and the rest will be recorded in the service trace.  If you need multiple OOM dump for analysis, you may modify the parameter oom_dump_time_delta (seconds) by running the alter system alter configuration command.

global.ini -> [memorymanager] -> oom_dump_time_delta =
If you set the parameter for example to 600, the minimum interval between two OOM dumps will be two hours (600seconds)

The following command  also will set the interval to 10 minutes.

–          ALTER SYSTEM ALTER CONFIGURATION (‘global.ini’, ‘SYSTEM’) SET (‘memorymanager’, ‘oom_dump_time_delta’) = ‘600’ with reconfigure;

To deactivate:

–          ALTER SYSTEM ALTER CONFIGURATION (‘global.ini’, ‘SYSTEM’) UNSET (‘memorymanager’, ‘oom_dump_time_delta’) with reconfigure;
