Configuration of 10g Data Guard Broker and Observer for Switchover

Configuring Data Guard Broker for Switchover, General Review.

On a previous document, 10g Data Guard, Physical Standby Creation, step by step I did describe how to implement a Data Guard
configuration; on this document I'm adding how to configure the broker and observer, setup the database to Maximum Availability and
managing switchover from Data Guard Manager, DGMGRL.
Data Guard Broker permit to manage a Data Guard Configuration, from both the Enterprise Manager Grid Control console, or from a
terminal in command line mode. In this document I will explore command line mode.
Pre requisites include the use of 10g Oracle server, using spfile on both the primary and standby and a third server for the Observer,
and configure the listeners to include a service for the Data Guard Broker.
