During update or insert on 1 table, is there a way to update a table that is on a different DSN? I want to interface 2 systems that are using different databases and would like to have a trigger that could do such updates. Thanks.

You can create a database link from one Oracle database to the other one. This gives you access to reference remote tables from within your trigger.
This solution has a the merits of simplicity but is not the most efficient (consider bulk updates) or robust (consider downtime of the remote database).
Oracle Replication is a full-on solution that allows you to trade-off consistency, availability , performance, etc.
