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?
