We are in oracle 11gR2 in windows. Our cloud control version is 12c. I always getting alerts that disk device 137 is 88% busy or above 90%. It happens specifically for this disk number and another one is 69. I looked up performance monitor in windows and i see that disk 137 in B drive which use for back up and recovery. I saw the live disk performance and i see that it runs oracle.exe and kfod.exe Can you guys tell me how i can find what is causing the high disk spike? if i get alerts at 6.00 am in the morning, how i can find what was causing the alert this time period?
