Introduction & Overview of Golden Gate
What is Oracle Golden Gate ?
Oracle’s Strategic Data Replication solution
Delivers Real-time access of Real-time information
Improves the availability, reliability and performance of
critical data across the enterprise
Copyright © 2017 Tech Mahindra. All rights reserved.
 Enables the exchange and manipulation of data at
transaction level
 Available across multiple, heterogeneous platforms
across the enterprise
 Modular architecture gives flexibility to extract and
replicate selected data records, transactional changes
and changes to DDL across a variety of topologies.
Introduction & Overview of Golden Gate Cont..
What does Golden Gate do ?

Golden Gate Components
 Manager
 Extract
 Trails
 Data Pump
 Collector
 Replicat
Copyright © 2017 Tech Mahindra. All rights reserved.
Overview of Manager
 Control process of Oracle Golden Gate
 Must be running on each system in the Oracle Golden
Gate configuration
 One manger process can control many extract or replicat
processes
Copyright © 2017 Tech Mahindra. All rights reserved.
Overview of Extract
 Extraction Mechanism in Oracle Golden Gate
 Can be configured for the following
 Initial loads
 Change Synchronization
 Can be captured from a data source of :
 Table
 Database Recovery logs or Transactional Logs
 Third party capture module
Copyright © 2017 Tech Mahindra. All rights reserved.
Overview of Trails
 Supports the continuous extraction and replication of
database changes
 Golden Gate stores the records of captured changes
temporarily on disk in a series of files called a trail
 A trail can exist on
 Source system (Extract Trail)
 Intermediary system
 Target System (Remote Trail)
Copyright © 2017 Tech Mahindra. All rights reserved.
Overview of Data Pump
 Secondary extract group within the source
 Primary extract group “Extract” writes to a trail on the
source
 Data Pump reads the trail and sends the data over the
network to a remote trail on the target
 Can perform data filtering, mapping and conversion or it
can be configured pass through mode.
Copyright © 2017 Tech Mahindra. All rights reserved.
Overview of Collector
 Runs on the target system
 Receives extracted database changes that are sent by
extract and write them to a Trail file
 Can receive information from only one Extract process,
So there is one collector for each extract that you use.
 Collector terminates when the associated extract process
terminates
Copyright © 2017 Tech Mahindra. All rights reserved.
Overview of Replicat
 Runs on the target system
 Reads the trail on the target system
 Re-constructs the DML or DDL operation and applies
them to the target database
 Like the extract can be configured for initial loads and
change synchronization
Copyright © 2017 Tech Mahindra. All rights reserved.
Golden Gate Supports
 Business continuance & High Availability
 Zero Downtime migration
 Data Integration
 Live Reporting, Real time Data Warehousing
 Live Standby database
 Supports Heterogeneous environments.
