System Packages are invalid

Hi there, I ran a query against dba_objects and found 1 system package invalid. I ran alter package compile package. After that I found 2 packages in dba_objects that were invalid. I ran the same alter package against those and now I have over 100 packages showing up as invalid? What do I do????? Thanks in advance.

The following object types are now invalid:

OBJECT_TYPE COUNT(1)
------------------ ----------
PACKAGE 23
PACKAGE BODY 132
PROCEDURE 3
VIEW 1

@?/rdbms/admin/catproc

to see whether fix your problem.

I've found catproc will cause invalid's, try
@?/rdbms/admin/utlrp
to sort this.

Did run @?/rdbms/admin/utlrp resolve it?

Sorry for the delay in my response!

I did run the utlrp.sql command. First time, it fixed some of the objects, but 20 were still invalid. I ran it a second time and now 0 are invalid. Thank you everyone for your help!
