Difference between total resident and database resident > 2GB


Dear All,

As per the SAP note 1840954 that difference between total resident and database resident memory should not be more than 2GB. However, for our HANA systems the difference is far more than 2GB.

Please note that we are licensed for only 64GB therefore global_allocation_limit is set to 90% of 64GB (as explained in SAP HANA Administration guide).

I thought that that value of database resident should be less than "Used Memory". Used memory is total amount of memory currently in use by SAP HANA i.e. Column tables + row tables + system tables + code& stack + DB management. This is a concern but I am unable to find the cause.

Can someone please suggest on this?
