I created a 'READER' id on production for our datawarehouse guys. The dblink connects from dw to production as user READER, and READER has select authority on the specific prod tables that they are supposed to be looking at.
DW has multiple ids. The single dblink solves the problem of an expotential number of dblinks.
The reader id cannot break anything, nor can it look into unauthorized tables.

If all he needs is select he cannot corrupt the DB if the DBA does not grant
unnecessary privileges. Folks
use dblinks all the time.

One of our development DBAs suggested today to build a private database
link between production and test database so that he can run some
queries against both at the same time. I am a little concerned because he
might make a mistake and accidentally corrupt the prod database. Anybody
out there who is doing the same thing? Are there any other potential
ramifications?
TIA
