Hello,
I would like to know whether there are ways of administering dblinks? If yes, please what are they.
Thanks in advance.

Does it affect database performances, yes when you access it you obviously load the network and queries are often less performant over a db link.
Does it affect security, yes you open a door to the remote database, so take care with which user you connect to.
