Oracle Data Guard :

Oracle database has some tools and services through which oracle users can perform a lot of amazing operations on database. In those queues, the
"Oracle data guard" is one of the powerful tool. It ensures high availability,data protection and disaster recovery for production database.
It provides a set of services that create,manage more than one standby databases when the production database is under the disaster and corruption issues.

It contains the same and secure copy of production database and switched into production database when production database comes into loss or disaster.

Oracle data guard Configuration:

The Data guard configuration can contain one production database and nine standby database.The databases are dispersed in a network using Oracle Net,they are facilitated to communicate with each other.But its not mandatory to dispersed the database geographically.If you have much space,you can put it on the same machine where the production database is running.

Using Oracle data guard manager,you can manage and maintain both primary and standby databases.

Data guard services:

Data guard works with the help of these 3 and more nested services which are as follows:

1. Log Transport Services:
It transmit the redo data from primary database to standby.

2. Log Apply Services:
After log transportation,this service applies the transported archived redo logs onto the standby database for synchronization of database with the primary database

3. Role Management Services
Role Management Services enforces an operation called "switchover or a failover operation".which is helpful to switch one of the standby database into production database.
