I'm playing with HANA SPS6 Developer Edition on Cloudshare. While about 19.5 GB RAM is available from the OS point of view, as can be seen in "free -m" output, most of this memory is allocated by HANA processes themselves. Actually, I see that less than 3GB is available for user data and it is very tight restriction, especially given the in-memory nature of HANA.
I wonder if it is possible to decrease the memory allocation by some HANA processes, except hdbindexserver of course. How can I check if the memory allocation by various HANA processes is adequate? Is it possible to change it?
Thanks in advance
