Zero memory administration on AIX

Hi All,

Can anyone here guide me about Zero Memory administration on AIX for Kernel 742.

What I have to do in case of Zero memory administration , like what are the parameters needs to be removed and added ?

What should be PHYS_MEMSIZE value if I am having 30GB of Physical RAM ?

I have gone through the SAP Note - 2085980 , But let me know the parameter shown in the list to be removed or just we need to adjust it as per Kernel default in Instance profile?

Thanks
