DB2 V8.2 has a new envir. var.
DB2_USE_ALTERNATE_PAGE_CLEANING=YES
The docs. mention that this will make DB2 ignore chngpgs_thresh and use
softmax to even the rate of writing out of the bp's.
What agent process then takes over.
On a workload of 10000 trans./min., I get over 9000 bp's writes out of
my snapshot. However, LSAN Gap Cleaners, Thereshold Cleansers and
Victim Page Cleaners are all = 0
So what does the cleaning???
Thanks, Pierre.
