More than 2TB memory limit for z/VM

Customer's Oracle DB 19c is growing rapidly as the end-users increase from 14k to 20k. In the coming year, they expect to reach 60k users.

More memory is required to eliminate performance and log-in issues. The current z/VM 7.2 LPAR only has 2TB real memory limit while the guest has 1TB limit. Current z/VM guest with Oracle DB PROD will be allocated with 800+GB for 30k users. We expect more than 1TB is needed for the z/VM guest to accommodate final target of 60k users.
