Hi experts,
we noticed this from OEM(Oracle Enterprise Manager) first. I also extracted MeasureWare data which has free memory and page-out data for one week. You can see from 13:10 to 14:10 on Nov.15th, some consistent page-out happened while there were more than 25GB free memory (about 55% memory utilization). Could you help explain why this happened and should this be a concern to us?
Thanks.
