This is because the optimizer_dynamic_sampling parameter is not a “multioption” parameter (which is not string, number or boolean type, but accepts a parameter from predetermined list).

In other words, there are no predefined valid values set for int, boolean and string type parameters, thus they don’t have any values in X$KSPVLD_VALUES

Thanks for all the useful scripts.

I tried pvalid with optimizer_dynamic_sampling and returns no rows.

show parameter returns result.

Interesting finding with ALTER SYSTEM.
