    Unanswered: Configuring Block Based Area

    Hi All,
    To enhance the prefetching contigous area, When configuring the bufferpool, there is an area call numblockpages and blocksize, what is the rule of thumb to configure this ? Any diff recommendation for DW and OLTP? Thank You!

    I have heard that 3-5% of the total bufferpool for data warehouses. O% for OLTP (unless there are some table scans going on).
