Advanced replication environments that support an update-anywhere data model
can be challenging to configure and manage. To help administer advanced
replication environments, Oracle provides the Replication Management section

It is essential that every detail is correct before using replication manager,
customers frequently miss out one of the initial steps and this causes the
replication environment to behave inconsistently. This article is intended to
guide customers through the initial configuration steps that must be performed
before using Replication Manager to setup a replication system. It does not
cover how to build replication groups or objects, Oracle Support Services
recommends customers use Enterprise Manager Replication Management for this.


This article is also aimed at customers who wish to use the replication
management API because they require the additional flexibility it provides or
they wish to use the trusted / untrusted security models.

Versions 8.1.x, 9.0.x and 9.2.0 ,10.2.0,11.1,11.2.x have been tested using this article.
