Hello everyone -
We have a database server which is choosing to swap though there is plenty
of free memory.
Any pointers on what to check are much appreciated..
Environment:
Red Hat Enterprise Linux Server release 6.7
Oracle EE 12.1.0.2
This server has 2 instances
Check out your kernel value for vm.swappiness. I believe the default is
60. I've set mine to "0", which is the equivalent of using swap when
it's actually needed, instead of being proactive about it.
Having the default value could explain what you're seeing.
