The document outlines Oracle GoldenGate 12c solutions, specifically focusing on uni-directional configurations and the integration of data tools. It discusses current and future trends in data replication and transformation, emphasizing the increasing demand for real-time data and diverse data sources. Additionally, it details the processes involved in Oracle GoldenGate, such as manager, extract, data pump, and replicat processes, and mentions the role of the IOUG Data Integration Special Interest Group in promoting these tools.

Agenda
• Oracle GoldenGate 12c Solutions
• Oracle GoldenGate 12c Uni-Directional
Configuration
• IOUG Data Integration Special Interest Group
(SIG)

3. 3
Legacy/Traditional Replication and ELT Tools
Tools:
1. Export/Import (Datapump/Traditional)
2. Advanced Replication
3. Streams
4. Warehouse Builder
Replication/Transforming data has been around in some form
for a really long time.
Other Venders Tools:
1. Dell Shareplex
2. SQL Server Transactional Replication/Sync Framework

4. 4
Present/Future trends of Replication and ELT
Tools
Question:
What product can help meet these trends?
• The need to always move/transform data will continue to
increase in the future.
• Requirements for real-time data/metrics will continue to
increase.
• More data sources will be required regardless of vendor
(i.e. Oracle, IBM, Microsoft, etc…)

Scenario
ACME company wants to build an online reporting system
that will provide guarantee access to data for a critical
business system.
Requirements:
1. Provide real-time data for reporting
2. Map data between different schemas
3. Maintain availability of data at remote site

8. 8
Uni-Directional Solution
One way replication between databases
Used for:
1. Query offloading/Reporting
2. Near-Zero Downtime Migrations
3. Application Integration
4. High-Availability Support
ACME.* ACME_RPT.*

9. 9
What is required?
Processes to ensure replication:
1. Manager
2. Extract (capture)
3. Data Pump (extract – shipping)
4. Replicat (apply)
ACME.* ACME_RPT.*

10. 10
Manager Process
Performs:
1. Starts/Restarts processes
2. Manage port numbers (static/dynamic)
3. Trail File Management
4. Create reports for events, errors and
thresholds
The manager process is the controller process within the
Oracle GoldenGate environment.

11. 11
Extract Process
Performs:
1. Reads online redo log/archive logs
(transactional logs)
2. Writes extracted transactional data to trail files
The extract process is used to perform change data capture
from the source database.

12. 12
Data Pump Process
Performs:
1. Protects against network failures
2. Consolidate data from multiple sources
3. Distribute data to multiple targets
4. Used for file adaptors (Flat File / Java)
The data pump process is a secondary extract that is used to
help send data over a network.

13. 13
Replicat Process
Performs:
1. Applies transactions in chronological order as trail files
are processed
2. Maps and transforms data
3. Performs Conflict Detection and Resolution
The replicat process is the apply process within the Oracle
GoldenGate environment.

14. 14
Trail Files
Performs:
1. Stores transactions in chronological order
2. Created by extract
3. Can be read by extract/replicat
Oracle GoldenGate binary files used to store transactions in
chronological order for shipping and applying to the target
side.

15. 15
GLOBALS File (Optional)
• File used store global parameters that relate to the Oracle GoldenGate
as a whole.
• All parameters in file apply to all processes for the instance
• Parameters in file can be overridden by process specific parameters
• Does not need to exist before starting processes rather is read by each
process as they are started
Example:
GGSCI> edit params ./GLOBALS

Files
Capture (extract): committed transactions are captured (and can be filtered) as they occur by reading the transaction logs. As of
V.11.2.1, GoldenGate offers two options for capture for Oracle; Classic & Integrated Capture
Trail: stages and queues data for routing.
Pump: distributes data for routing to target(s).
Route: data is compressed, encrypted for routing to target(s).
Delivery: applies data with transaction integrity. New with
GoldenGate 12c, Integrated Delivery (replicat).

Parameter Files
Parameter files is where the Oracle GoldenGate magic is
performed.
Editing parameter files can be done two ways:
1. From GoldenGate Service Command Interface (GGSCI)
2. Edited using a text editor (vi, textpad, etc..)
Example:
GGSCI> edit params <process name>
