iWay Log Event Adapters (Change Data Capture)

Overview

Using the iWay Integration Suite, you can take advantage of iWay Change Data Capture (CDC) solutions for managing incremental data loads. iWay CDC offers effective solutions to the challenges encountered when performing incremental loads from data source tables, systems, and data warehouses.

iWay CDC solutions are available for:

  • Informix
  • Microsoft SQL Server
  • Oracle

iWay Change Data Capture (CDC) Solution for Informix

The iWay Informix CDC Agent is a key component of the iWay CDC Solution for Informix, which enables integration between IBM Informix Dynamic Server (IDS) and other iWay accessible enterprise systems. The agent accomplishes this task by exploiting the IDS 11.5 CDC API, a significantly improved technology for Change Data Capture (CDC) over previous methods. The second component of this solution is the iWay Log Event Listener that runs on the target Oracle database server.

The combination of iWay Integration Technology and the IDS 11.5 CDC API provides:

  • Real-time CDC capture and staging of CDC records in a standard form.
  • Remote retrieval of IDS CDC records via shared file system.
  • Natural queuing while network connections are unavailable.

This architecture exploits the IDS logging facilities, so that overall impact upon existing IDS systems is minimal. Security is ensured by limiting CDC data capture to only preselected schemas, tables and columns with an existing DBMS.

iWay Change Data Capture (CDC) Solution for Microsoft SQL Server

The iWay CDC Solution for Microsoft SQL Server consists of the iWay Log Event Adapter for Microsoft SQL Server, which is used to integrate a Microsoft SQL 2000/2005/2008 database with an Oracle and SQL database with near real-time data replication. The iWay Log Event Adapter for Microsoft SQL Server consists of several components. The key component is the SQL Server wrapper (C# .NET client), which interacts with the server-side components.

iWay Change Data Capture (CDC) Solution for Oracle

The iWay CDC Solution for Oracle consists of the iWay Log Event Adapter for Oracle. This adapter is designed to replicate data changes from Oracle 10g/11g to Oracle 10g/11g or SQL 2000, 2005, or 2008. The iWay Log Event Adapter for Oracle uses a listener to capture the changed data from the Oracle redo logs using Oracle LogMiner.

The following types of supported operations can be captured from the source Oracle 10g/11g database table:

  • INSERT
  • DELETE
  • UPDATE
  • DDL

    Note: DDL can be captured only and not replicated.
