Hi,
I'm trying to increase the value for the parameter memory_target target, but Oracle complains that it cannot shrink it.
Why does Oracle complain it cannot shrink the memory while I clearly want to grow it?
I know I can "fix" this by using scope=spfile and then bounce the instance, but I'm more interested on why this error occurs.
The operating system is Windows 2008 R2 Server
