I have a server having 90GB of RAM.
I have set MEMORY_TARGET to 60GB, because OEM showed me the following graph:
Which tells that, if you set the parameter to the value of 60GB, the performance will be the maximum. After 60GB, performance does not change.
Now we want to migrate our server to the virtual machine and my sysadmins want me to say the minimum preferable value for RAM to be allocated for the new server.
For that I need determine the minimum preferable value for MEMORY_TARGET. How to calculate it?
