Ok so a co-worker asks a question about an implied database link, i'm like "huh".

so a database link is NOT created in the source database but the userid/password are the same in both source and destination.

take for example

system on db1 and db2 has a password of x12345.

I do a select count(*) from dba_users_at_db2 while connected on db1 and it connects and returns a result set w/o a db link being created.

I've been enlightened again of something new about oracle.

so the question posed is, for a named db link you do "close" it, how do you close an implied link?
