Re: Resident memory and used memory large gap

A little bit off subject, but a question popped up into my head:

 

So memory manager requests more memory from OS if there is no more memory in HANA pool. This will continue until a "predefined allocation limit" (I guess the global_allocation_limit). So, I just wonder, what would happen if our resident memory is let's say 200 GB, and we lower the allocation limit to 150 GB - what would the monitors show? (yeap, we  can bring the allocation limit back to what it was right after as it's dynamically switchable).
