How to determine the value of kernel.shmall
I saw the Oracle E-Business Suite Installation and Upgrade Notes Release 12 (12.1.1) for Linux x86-64 [ID 761566.1]
the value of kernel.shmall is set to 2097152
I assume that the default system have 4GB ram (kernel.shmmax Half the size of the physical memory (in bytes), and at least 21474836482 ) Half physical memory =2G total = 4G
than the kernel.shmall = 2097152 ( Page size assume 1024?)
So if I have 24G physical memory
the kernel.shmmax=12884901888 (Half physical memory)
kernel.shmall=3145728 (12884901888 / 4096 [Page Size]) Page size is retrieve by command getconf PAGE_SIZE
is it correct?
Thanks in advance
