MQSeries_Bufpool_High_GetPage_IO  
Situation Description
Suggested Actions
Situation Description

High % of GetPage requests resulting in Pageset I/O.

The default "GetPg IO %" threshold value in the situation formula is a suggested value.

The threshold value can be customized to suit your own environment.

 

Suggested Actions

Increasing the buffer pool size might reduce the percentage of GetPage requests, resulting in more page requests being found in the buffer pool. If it does not, it might be that there are long delays between message PUTs and GETs. Check the Buffer Pool Statistics workspace for statistics associated with this situation. To access this workspace, click the Buffer Pool Statistics navigator item. The Buffer Pool Statistics workspace is available only on z/OS.
