the problem with compiling individual packages is that you might inadvertently invalidate others. you should also programmatically check package dependencies too so you dont break any accidentally.
if you're only compiling package bodies, this shouldn't be an issue, but if youre also compiling specs, this is something you should keep an eye on.
i wrote an application that uploads new packages i commit in cvs to our database and then recompiles them. it then reports whether or not compilation was successful. this helps eliminate alot of user error when people manually recompile packages in HA environments. however, i recompile the entire schema when i do this (this is not something run very often). i can get away with this at my shop because the schema is very small, but this might not be a practical solution for everyone.
this is how i check for dependencies:
FROM public_dependency pd, user_objects uo
WHERE referenced_object_id IN (select object_id from user_objects where object_name= UPPER(?))
AND uo.object_id = pd.object_id
this is useful for saving a snapshot of current package (in case of reversion):
SELECT TEXT FROM USER_SOURCE WHERE NAME = ?
this is how you can recompile the schema:
DBMS_UTILITY.COMPILE_SCHEMA(?, TRUE, TRUE);
i do a check for invalid objects in the schema before i even start (And exit with error if any are found) :
SELECT OBJECT_NAME, STATUS
FROM USER_OBJECTS
WHERE (OBJECT_TYPE='PACKAGE' OR OBJECT_TYPE='PACKAGE BODY')
AND STATUS <> 'VALID'
Hope this info helps.
