MARTDBA schema contains everything, SP, tables, vies, sequences, etc.
MARTUSER have access to all views and tables, execute all SP, and get sequence number, etc. from MARTDBA schema,
the only thing it cant do is delete or create objects.
MARTUSER rights are given through synonyms. thats why i cant see anything besides synonyms in MARTUSER schema.
Through this workaround i can see in openaccess exactly the same objects as using Oracle developer tools Treeview. (tables,views,sp) from MARTDBA that is what i was expecting.
*note:im using oracle 9i.
