How to set the shared memory for Oracle on Linux 7

Hi, I'm trying to install Oracle on Linux 7.0, mentioned on the installation instruction, I have to setup the shared memory for Oracle before I install.
It's said that the kernal parameters are located in the '/proc/sys' directory as virtual files. Under this directory, I only can find 'shmall' and 'shmmax'. But where are others. I wasn't allowed to create a new one even login as root.
Any help is appreciated.
Thanks.

Set the kernel parameters for shared memory in

/usr/src/linux/include/asm/shmparam.h and

semaphores in

/usr/src/linux/include/linux/sem.h.

Thanks Amar, but do I have to re-compile something of the Linux component?

Generally the default settings are sufficient. However, if you change any of the settings then I am afraid you will have to recompile the kernel :(
