the amount of ZFS File Data,Page cache and kernel are too high on the system
hi,
On our database RAC (2nodes) the amount of ZFS File Data,Page cache and kernel are too high on the system of node1 but seems normal on the second node (the difference is very important between the values), how we can resolve this issue.
total physical memory:256 Go
3 instances are running on the server
instance1:
SGA_TARGET=75Go
PGA_AGGREGATE_TARGET=25Go
instance2:
SGA_TARGET=75Go
PGA_AGGREGATE_TARGET=10Go
instance3:
PGA_AGGREGATE_TARGET=4Go
