./hugepages_settings.sh => Kernel version 5.15 is not supported by this script

in Database Administration (MOSC) 9 commentsAnswered ✓

Hello,

Oracle 19.20 SE. I would like to configure huge pages but unfortunately the script from Oracle does not help me as my kernel is not supported.

Do you guys know any workaround ?

I have following SGA_Target settings for both instances (Prod + Test): 144G + 30G = 174 G

I have currently following settings:

HugePages_Total:  87200
HugePages_Free:    21
HugePages_Rsvd:    2
HugePages_Surp:    0
Hugepagesize:    2048 kB

Orachk reports critical issue with following:

Total current hugepages (87200) should be greater than or equal to estimated requirements for all currently active SGAs (89154 )

89154 * 2048 /1024 /1024 = 174,13, so looks like huge pages should be bigger then sum of SGAs.

Should I just trust this new value (89154) or there is a way to make this script working.,

Howdy, Stranger!
