This is for an Oracle install, yes?
"On x86-64 platforms, SHMMAX can be much larger than 4GB since the virtual address space is not limited by 32 bits.". NOTE: That says "can be" not "should be" or "has to be". The link also discusses the implications of not setting the correct SHMMAX size. Good Luck. |
Hi Habitual;

2. Any difference between Virtual Space vs virtual address space ? All operations performed by RAM. 3. How processess have physical address ? 4GB – 1byte” is related to the limitation on the 32 bit (x86) systems 4. here 1-byte what it indicates ? SHMMAX is used for SGA , oracle processes only using this area 5. Won't LINUX process use SHMMAX area? Quote:
