hugepages setting

Hello all,

I am trying to determine if our hugepages are set too high and causing system memory issues. I am not the SA nor have any claim to know a lot about OS configurations. I just want to make sure we are not starving the OS with incorrect settings.

I ran hugepages_settings.sh, This script is provided by Doc ID 401749.1 from My Oracle Support.

the output is  Recommended setting: vm.nr_hugepages = 25734

our settings are

vm.nr_hugepages = 48829

vm.nr_hugepages_mempolicy = 48829

$grep Huge /proc/meminfo

AnonHugePages:     0 kB

HugePages_Total:  48829

HugePages_Free:  23099

HugePages_Rsvd:    0

HugePages_Surp:    0

Hugepagesize:    2048 kB
