Run/execute multiple procedures in Parallel - Oracle PL/SQL

Question

I have an Activity table which is getting all the table events of the system. Events like new orders, insertion/deletion on all the system tables will be inserted into this

Answer 1

It is impossible in general case without jobs, and it will make multiple sessions for this. There is no such thing as multithreading PL\SQL with a few exceptions. One of them is parallel execution of sql statements [1]. So there are some attempts to abuse this stuff for parallel execution of PL\SQL code, for example try to look here [2].

But as i've said it's abuse IMHO.
