I looked for these three objects querying dba_objects with their object_id and it returns


ADV_SQLACCESS5150248
ADV_SQLACCESS9067727
ADV_SQLACCESS2676493


Are these warnings worrying? 

How should I fix them and what is going on exactly?
I expect this is bug 5120780 fixed in 10.2.0.4 (a quick search on Metalink would have told you).
