3380524 - High persistent memory utilization during online partitioning


During online partitioning (KBA 2044468), you notice that the entire table is re-created and stored in persistent memory (KBA 2700084).

This leads to a high utilization of the persistent memory, possibly causing the /hana/pmem mounts being used 100% (on OS level execute df -h grep -i pmem). 

Therefore you would like to know how to decrease the persistent memory occupation during online partitioning.



Persistent memory is supported with SAP HANA 2.00.035 and higher. For more prerequisites like supported operating systems please refer to SAP Note 2618154.
