We have an automated job which recompile all invalid objects in database everyday. When it tries to re-compile the SYS.DBMSOBJG Package the above error comes up. I tried to recompile it directly but same error. We have another 7.3 instance. It is Ok on that and can compile successfully.. What should I do? Is it safe to drop the package and re-create a vald copy of it from another database. Remember it is SYS user.
