Description
Enrolling in this Oracle GoldenGate 11g training will help you develop your installation and configuration skills.
By interacting with top Oracle instructors, you'll be able to ask questions as you learn to solidify your understanding.
Objectifs

  • Explain Oracle GoldenGate Advanced Configuration options
  • Describe and take advantage of the new Integrated Capture to replicate complex data types and compressed data, currently unsupported by Classic Capture
  • Install and deploy Oracle GoldenGate Integrated Capture components
  • Configure and implement the Oracle GoldenGate Event Marker system, to enable data transformation based on event records in the transaction logs or in the trail files
  • Master Oracle GoldenGate facilities to detect and resolve data conflicts in active-to-active replication implementations
  • Perform zero-downtime database migration
  • Familiarize the student with Data Conflict Avoidance Techniques
  • Set up and manage advanced deployment models, such as 3-node multi master replication configurations

SOMMAIRE

Oracle GoldenGate Integrated Capture

  • What is Oracle GoldenGate Integrated Capture?
  • Why it is Needed and What Additional Replication Features it Makes Possible
  • Comparing and Contrasting Classic Capture vs. Integrated Capture
  • How to Prepare a Database for Integrated Capture – Creation of Users, Assignments of Roles and Privileges, etc
  • Oracle GoldenGate Integrated Capture Deployment Modes
  • Configuring an Extract Process to Perform Change Data Capture Using Integrated Capture
  • Extracting Parameters Relevant to Integrated Capture

Oracle GoldenGate Event Marker System

  • Starting, Suspending, Stopping Processes, Performing a Transformation, Reporting Statistics, and Capturing Lag History Using the Event Marker System
  • Invoking Stored Procedures When Specific Events Occur Using SQLEXEC
  • Activating Tracing Following the Exceeding of a Data Threshold
  • Running OS Shell Commands at the Occurrence of Specific Data-Driven Events
  • Extracting Details Analysis of the TABLE, MAP, FILTER, WHERE and SQLEXEC Statements
  • Implementing Event Marker Actions on the Extraction Side and on the Delivery Side of Replication

Data Mapping, Data Selection/Filtering and Data Transformation

  • TABLE (for Extract) and MAP (for Replicat) Options Which Allow for Data Selection
  • COLMAP and COLMATCH Options
  • Exploring Simple Filtering (Achieved Through the WHERE Clause) and Complex Filtering (Using the FILTER Clause)
  • Data Transformation Functions: Enabling Concatenation, Substitution, Case Changing, Numeric Conversion and Date Conversion
  • SQLEXEC Parameter to Invoke Stored Procedures or to Perform Native SQL Queries

Custom Behavior Through User Exits

  • The CUSEREXIT Parameter and its Options
  • User Exit Mandatory Parameters: EXIT_CALL_TYPE, EXIT_CALL_RESULT and EXIT_PARAMS
  • The EXIT_CALL_PROCESS_RECORD Function
  • Oracle GoldenGate Callback Routines Invoked Through ERCALLBACK
  • The usrdecs.h “C” Include File
  • JMS and Flat File Using Oracle GoldenGate Application Adapters
  • Connecting to the Java Subsystem Through the Java Native Interface (JNI)

Configuring Zero-Downtime Migration Replication

  • Zero-Downtime Migration Prerequisites

Bidirectional Replication: Two-Node Configuration

  • Bi-Directional Replication
  • Multi-Master Replication
  • Data Conflict Types
  • Getting Before Image Information from Source Database
  • Using RESOLVECONFLICT
  • Handling UPDATEROWEXISTS in Conjunction with USEDELTA, USEMAX, and IGNORE
  • Exceptions MAP Statement
  • Creating and Populating Exception and Discard Tables

Conflict Detection and Resolution – Custom Techniques

  • Workload Partitioning
  • Geographic or Topic-Based Segmentation
  • Primary Key Generation
  • Custom Conflict Resolution Techniques: Quantitative Methods for Conflict Resolution and Data Convergence

  • Automatic Data Convergence of Numeric Values Based on Additive Value or Average Value

Multi-Master Replication Topology – Three-Node Configuration

  • Handling Multi-Master Configurations: Additional Limitations Compared to Active-Active
  • Dealing with the Lack of Support for DDL Replication
  • Data Convergence and Latency in a Multi-Master Topology
  • Decreasing Complexity by Enabling Segmentation and Node-Based Partitioning in the Application
  • Minimizing Data Conflict by Minimizing Latency
  • Resolving Simple Conflicts Using RESOLVECONFLICT with USEMIN, USEMAX and USEDELTA
  • Combining RESOLVECONFLICT with UPDATEROWEXISTS, INSERTROWEXISTS, DELETEROWEXISTS, UPDATEROWMISSING and DELETEROWMISSING Clauses to Identify Source of Conflict Errors
  • Increasing Troubleshooting Information Captured in Error and Discard Tables Using Oracle GoldenGate Facilities
