I'm looking at the results of a 10053 trace from 9i. I'm not finding any real documentation for the following parameters in the base table access cost section:
tb_sel rsc_cpu rsc_io ix_sel I believe that these all combine somehow to define a cost for a specific index access but I'm not sure how to calculate this cost. I think this is new for 9i, can someone shed some light on these? RF Robert G.
