Hi,

what are the advantages of pinning ?

Pinning is nothing but making the frequently used storedprocedures,packages or functions reside permanently in the SQL and PL/PLSQL memory areas[[library cache]], they do not need to be loaded and parsed from the database, which saves considerable time.
Pinning objects in the shared pool can provide a tremendous increase in database performance
The pl/sql command to pin a package
SQL> execute dbms_shared_pool.keep(package name);

Can a Single Procedure or Function be pinned instead of a package.
The below proc requires another parameter i.e., 'P' for Package,'R' for trigger etc..
execute dbms_shared_pool.keep(package name,'P');
