Hi,
I have set pga_aggregate_target parameter value and workarea_size_policy to Auto.
In this case setting sort_area_size and hash_area_size are considered obsolete right?
in My system
hash_area_size is set to 131072
Does this setting has no effect in automatic pga memory management?

In most cases, yes but you can set it in session (with policy to manual) to overwrite the usage of automatic memory for a specific task that requires more memory than the common one.

Yes, unless you modify the policy at session level.
