We always compile INVALID objects as part of change (in your case ALTER TABLE).   sqlplus / as sysdba:
SQL> @?/rdbms/admin/utlrp.sql  

btw, "Dba_Dependencies" can provide you details on dependent objects.

I want to understand that if I alter some table which has lots of other dependent objects like Package,procedure,view etc. These dependent object will be invalid. Do I need to compile them or some of them will be compiled automatically when they are executed again by the application. Any Reference to check as what will be invalidated and at which condition like when the actual column been used in the db objects are modified or even table is subjected to DDL.
