Virtual Memory parameters values

edited Jul 22, 2023 1:21AM in Database - RAC/Scalability (MOSC) 1 commentAnswered

Hi Oracle Community,

I am planning to configure RAC on RHEL 8 and I am looking for some recommendations on the following parameters:

vm.swappiness 
vm.dirty_background_ratio 
vm.dirty_ratio 
vm.dirty_expire_centisecs 
vm.dirty_writeback_centisecs

Would anyone be able to provide some advice on these values? I am particularly interested in understanding the impact that these values will have on performance and storage.

Thank you for your help!

Sincerely,

Alwaleed

Howdy, Stranger!
