Ana, you have been using db links all the time, but when you are running LDAP or Oracle*Names, and your databases have GLOBAL_NAMES set to true. then you have db link created for each service name, exactly as if CREATE DATABASE ORA.WORLD LINK USING 'ORA.WORLD'; was ran. In addition to that, databe slink can contain username, so that you don't have to have identical passwords on all databases but are free to use DBMS_RANDOM for password generation. or On 02/12/2004 10:51:43 AM, Ana Choto wrote: > > > > > I'm not sure if you found a solution for this yet.
