The following SAP HANA alert is issued:
Alert 46: Runtime dump files
The SAP HANA database has generated out-of-memory (OOM) trace files in the trace directory (/usr/sap/<sid>/HDB<nr>/<nodehostname>/trace) using the following naming convention:
Example for an actual file name:
You experience memory shortages and you have generated a runtime dump as described in SAP Note 1813020.
In HANA DB Studio, on the Diagnosis Files tab, you find trace files when entering the filter string 'oom' or 'rtedump' and sort by the Modified column.
Files with a name containing 'composite_oom' are linked to the statement memory limit. See SAP Note 1999997 ("Is it possible to limit the memory that can be allocated by a single SQL statement?") for more details. These files don't indicate overall OOM situations but a high statement-specific memory consumption. This scenario is not discussed in detail in this SAP Note. Normally the analysis is quite straight-forward because it is already clear which activity ran into the memory limit.
