Setting up connection between 2 oracle instances for replication
===

Hi everyone i have problem with setting up connection between 2 oracle instances for replication. I can connect wia sqlplus using string like SQL > connect root/12345@orcl1, but I can't create query: CREATE DATABASE LINK remotedb 
CONNECT TO root IDENTIFIED BY 12345
USING 'orcl1'; and also I cant set up it throutht oracle database control. Error that I get is username or password of remote master isn't correct.
