Memory Management for services
SAP HANA resource usage
SELECT service_name, database_name, round(effective_allocation_limit/1024/1024/1024, 1) AS MemLimit, round(total_memory_used_size/1024/1024/1024,1) AS MemUsed FROM "SYS_DATABASES".m_service_memory
If the MemUsed is close to the MemLimit , you may encounter problems allocating memory.
Alternatively, you can run the Linux free command at the command line to see the free memory resources:
total used free shared buffers cached Mem: 6 3 3 0 0 1 -/+ buffers/cache: 1 4 Swap: 2 0 2
The key number is in the second row (-/+ buffers/cache) in the free column. If this number is low, (e.g. 1 GB) you may have run out of memory when performing your recent operation.
