Hello Joules
Now you know me, I'm not a DBA - I do well in excess of 20 hours a week for one thing.
But, if you're trying to identify invalid packages, I think you can do
SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE LIKE 'PACKAGE%'
AND STATUS = 'INVALID'
I don't have access to a database at home, so I can't verify this as being wholly accurate. e.g. not sure if the status column is actually called 'STATUS'. I confidently predict someone will shoot me down in flames for something I got wrong!
Any road up, hope this helps
