RE: optimizer_index_cost_adj and optimizer_index_cachingIn windows I set 
DB_FILE_MULTIBLOCK_READ_COUNT  to 16 (guy harrison suggestion)
which would be the value for MREADTIM in 9i.

And which is the complete name for MREADTIM and SREADTIM please.
:)


According to the Metalink note you can even achieve 8.1.7 behavior when you set 
MREADTIM = 1.2 * SREADTIM and MBRC=8, but I haven't tested this. And finally I 
haven't heard for a negative feedback till now and this counts as well. But as 
usual happens in real life also the system stats is not solving all problems.
