The three figures reported as New ( , , ) are the cpu_cost, io_cost, and temp_space of the new cpu_costing algorithm; and the final cost is io_cost + (scaled) cpu_cost.
Table 1-1. fm Page 9 Tuesday, September 27, 2005 7:02 AM CHAPTER 2 ■■■ Tablescans A t first sight, you might think that there couldn’t be a lot to say about tablescans, but you may be in for a surprise. Since the cost calculations for tablescans are nice and simple, I thought I’d use them in this early chapter to demonstrate the four different strategies for cost based optimization that have evolved over the years, briefly outlined here: • Traditional: Simple counting of read requests • System statistics (1): Accounting for size and time of read requests • System statistics (2): Accounting for CPU costs, and size and time of read requests • System statistics (3): Accounting for caching, CPU costs, and size and time of read requests The traditional method appeared in Oracle 7, and has been enhanced continuously since.
Every extent in my table had a couple of blocks taken out for space management bitmaps—2 blocks out of 128 since my extents were 1MB; the extra cost is largely due to the effect of those blocks on the high water mark of the table. Again, if you are advised to move an object into an ASSM tablespace for performance reasons (specifically to avoid contention on inserts), be just a little cautious—this is just one of the irritating little side effects of ASSM. CPU Costing One of the most serious defects of the optimizer prior to 9i was its assumption that single-block reads and multiblock reads were equally cost effective.
