    Ahn...? what about:

    SELECT /*+ PARALLEL(table_name,parallel_processes) */ .... ?

    You need to read the concepts guide -- it has a section on how parallel query works, and it's nothing to do with dedicated or shared server.

    Just by giving hints, query is not subject to be processed parallely.

    there are many other things one might have to consider.

    abyhaysk,

    You're right. There are considerations about PARALLEL_MAX_SERVERS, PARALLEL_MIN_SERVERS, number of cpu's, access plan etc.

    I was pretty laconic (and lazy) because, as slimdave mentioned, there is no direct relation between parallel query and dedicated/shared server/OPS, I didn't understand what exactly he meant.

    Anyway, the docs pointed by you and slimdave have all the stuff.
