GLOBAL_REDO_STAT

GLOBAL_REDO_STAT displays the total statistics of XLOG redo operations on all nodes in a cluster. Except the avgiotim column (indicating the average redo write time of all nodes), the names of the other columns in this view are the same as those in the PV_REDO_STAT view. The respective meanings of the other columns are the sum of the values of the same columns in the PV_REDO_STAT view on each node.
