I'm a little bit mess for this Q. Anyone give a explanation?

[Prettyman]

I still can't understand this Q, anyone help?

[dba1]

I guess A, B & C.

[Prettyman]

Guess? Ans: BCE, but I'm a little bit mess for the meaning for this Q.

OK, I agree that 'A' is certainly an incorrect answer. 'B' is correct because the ONAMES server will infact store information for connections to distributed DBs via database links. 'C' is correct because ONAMES will store the locations of other ONAMES servers in the Region. 'D' is incorrect because registered dispatchers do not notify ONAMES, thus that info is not stored there. 'E' is correct because Connection Manager has the capability to work hand-in-hand with ONAMES.

Remember, ONAMES is all about "connections" form a client to a database, where ONAMES stores the "connection" information.
