Oracle GoldenGate 12c: Advanced Configuration for Oracle (D89113) – Outline
Detailed Course Outline
Oracle GoldenGate Integrated Capture/integrated Delivery
What is Oracle GoldenGate Integrated Capture? Why it is Needed and What Additional Replication Features it Makes Possible How to Prepare a Database for Integrated Capture – Creation of Users, Assignments of Roles and Privileges, etc Oracle GoldenGate Integrated Capture Deployment Modes Integrated Replicat/Apply Architecture Integrated Replicat: How it works Integrated Delivery in Detail Oracle Goldengate With Oracle Real Application Clusters Configuration
Oracle RAC, Oracle GoldenGate and Business Continuity Oracle GoldenGate Used in Combination with Oracle RAC Oracle GoldenGate and the Oracle Database File System (DBFS) Oracle DBFS and Oracle Clusterware Configuring Oracle GoldenGate using the DBFS file systems 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 Zero-Downtime Migration Topology Configuring Initial Setup and Required Steps Configuring Primary Extract, Data pump and Replicat for Fallback Simulating fallback Bidirectional Replication: Two-Node Configuration
Bi-Directional 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 Conflict Resolution Based on Time stamp or Trusted Source 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 Active Data Guard and Oracle GoldenGate.
