Tuning vm.swappiness and vfs_cache_pressure for Oracle database bare metal systems

Team,

Please share if anyone has tuned these parameters and set them to non default values for Oracle databases or for other applications. I'd like to know some details of your scenario and the logic thereof.

Thanks in advance. All patronage is appreciated.

Re: How to bridge enX to br0, br1, br2, br4

Okay, maybe I did not explain my situation.

When I use virtualbox, I can add upto 4 bridged interfaces to the VM, all based on a single physical host nic. How may I do the same in KVM?

How to bridge enX to br0, br1, br2, br4

Hi,
