Definition

Computed data buffer quality.

This key figure is calculated as rate by a formula:
100% - ((physicalreads - physicalreads_direct - physicalreads_directlob) / (sess_logicalreads - physicalreads_direct - physicalreads_directlob))

Non RAC / RAC Detail: Data buffer quality of the current instance.

RAC Total: Average over all instance-related data buffer qualities.

(Data source: gv$sysstat)

The appearance of a light (yellow / red) indicates that the difference in percent of at least 1 instance's value from the all-instances-average exceeds a certain limit. The limit values are maintained specific to key figures in table ST04N_LIM.
