AvePgCleanWriteTime (DB2UDB_BUFFERPOOL)

Indicates the average asynchronous write time that is required by the Database Manager page cleaners each time data is written from the bufferpool to disk. This parameter indicates the amount of input/output requests being performed by the Database Manager page cleaners and helps to determine the correct setting of the buffpage configuration parameter. 

The BUFFERPOOL DB2 Monitor Switch must be set ON to make this parameter active and collect data.

To reset this parameter's value, set monitor switch to OFF, and then set monitor switch to ON to begin monitoring this parameter again. This will reset the counters for all the parameters that are being controlled by the monitor switch.
