1) How will the CPU_COUNT parameter be affected with vPars?
2) Correct me if I'm wrong, as per my understanding with vPars, applications can share CPUs resources. If this is true, how will the Oracle instance know this? During Oracle instance start up, this value has already been taken by Oracle through the OS call.
3) What about memory sharing? If with vPars memory is also shared, then how will the memory dependent Oracle instance system parameters be affected?
The same holds true for memory. Although you won't be able to enlarge your SGA,
the additional memory can be used for sort area. If you know that you are going
to be able to allocate more memory during peak usage, you can take this into
account when sizing the SORT_AREA_SIZE parameter.
