OS390_Local_PageDS_PctFull_Crit

OS390_Local_PageDS_PctFull_Crit monitors to determine whether the percentage of slots in use on a local page dataset is greater than or equal to 35% and issues a Critical alert if the condition is true. When usage approaches 30%, paging efficiency begins to decline, and blocked paging disappears at about 35% occupancy. If this situation occurs, prepare to PAGEADD another dataset if the critical threshold is passed. If the current PAGTOTL setting in IEASYSxx does not allow another dataset to be added, it should be increased before the next IPL.

The formula is:

IF VALUE Page_Dataset_Activity.Dataset_Type EQ Local and VALUE Page_Dataset_Activity.Percent_Full GE 35
