Not a problem.
8. Within a namespace, no two objects can have the same name.
The following schema objects share one namespace:
Stand-alone stored functions
Each of the following schema objects has its own namespace:
Private database links
Because tables and views are in the same namespace, a table and a view in the same schema cannot have the same name. However, tables and indexes are in different namespaces. Therefore, a table and an index in the same schema can have the same name.
Each schema in the database has its own namespaces for the objects it contains. This means, for example, that two tables in different schemas are in different namespaces and can have the same name.
Each of the following nonschema objects also has its own namespace:
Public database links
Parameter files (PFILEs) and server parameter files (SPFILEs)
Because the objects in these namespaces are not contained in schemas, these namespaces span the entire database.
