Well, I'd suggest setting 'global_name = true' in your init.ora files. Then the database names in global_names have to be unique.

I don't want to mess with SIDs, what I need is a globally unique identifier of the database (or one with sufficiently small probability of being duplicated)

The reason I need this is because in the application a user may read some object from a database and when he tries to save the object back I need to be sure that the database used is the same as the one the object originates from (one usually deals with few objects from different databases)

So, if DBID is not unique how could I generate an almost globally unique number?
(I don't quite like calling SYS_GUID() because it returns RAW)

thanx,
