PRVG-12935
When performing a pre-installation check of Oracle 19c grid infrastructure, we saw:
PRVG-12935: The virtual memory manager tunable parameter "vmm_klock_mode" does not have expected "BOOT" value on nodes primary01
Let's check current value of vmm_klock_mode.
[root@primary01 /]# vmo -L vmm_klock_mode
NAME CUR DEF BOOT MIN MAX UNIT TYPE
DEPENDENCIES
--------------------------------------------------------------------------------
vmm_klock_mode 2 -1 -1 -1 3 numeric B
--------------------------------------------------------------------------------
We'd better to change the value to the expected one on both nodes.
[root@primary01 /]# vmo -r -o vmm_klock_mode=2
Setting vmm_klock_mode to 2 in nextboot file
Warning: some changes will take effect only after a bosboot and a reboot
Run bosboot now? yes/no no
You can reboot now or reboot the system later.
Check the value again.
[root@primary01 /]# vmo -L vmm_klock_mode
NAME CUR DEF BOOT MIN MAX UNIT TYPE
DEPENDENCIES
--------------------------------------------------------------------------------
vmm_klock_mode 2 -1 2 -1 3 numeric B
--------------------------------------------------------------------------------
Go back to Grid OUI, then check the pre-requisite again.
