Hi all,
I have a question regarding the global allocation limit setting within HANA. I understand that by default this is set to 0 and as a result HANA uses what memory it requires up to around 90% of available memory. My question is what is the behaviour when you actually set this to a value? I'll illustrate with an example.
I have a server with 200GB of memory. With one instance, HANA will use up to 180GB of the memory. If I want to install 2 instances on this server and have them use half the memory each, would I set the global allocation limit to 100 on each server, or 90 on each server? i.e. does HANA use 90% of the configured value, or the entirety of the configured value and it's left to the administrator to ensure there is enough memory for the system?
Thanks for your help
