We moved from tnsnames at each of our sites, updated via batch scripts, to storing the tnsnames info in Active Directory, and letting AD handle the replication for us. It's much easier to keep things in synch. It is easier for us leverage AD rather than setting up the OID databases and their replication.

Note this isn't for some enterprise-wide solution. While they do have plants all over the world, it's very rare that they share database info. I'm only dealing with one plant though it would be nice if are solution could be easily used by others. It seems like a real pain to setup OID since you have to dig it out of Application Server now. <snip>
