    CSQPDWP2 may need several passes over the bufferpool in order
    to calculate the number of pages written to the pageset for that
    particular checkpoint. However the code resets the number of
    counted pages on each pass and CSQP019I only reported the number
    written on the last pass.
    

Problem conclusion

  • CSQPDWP2 now correctly calculates the number of pages written
    to the pageset at checkpoint time.
