Dear all!
I have not understood about 2 concepts.

Note the difference between an application making a parse call for a SQL statement and Oracle actually parsing the statement. A parse call by the application associates a SQL statement with a private SQL area. After a statement has been associated with a private SQL area, it can be run repeatedly without your application making a parse call. A parse operation by Oracle allocates a shared SQL area for a SQL statement. Once a shared SQL area has been allocated for a statement, it can be run repeatedly without being reparsed.

Why does the Oracle parsing only allocate shared SQL area? Many documents I read which does not discuss about this.
Please tell me!
Thank you!
