PowerExchange Overview

PowerExchange Overview

PowerExchange can perform the following functions to synchronize a data source and data target:
  • Bulk data movement to materialize or entirely refresh a data target.
  • Change data capture to keep a data source and data target synchronized.
PowerExchange bulk data movement can move large amounts of data between different systems efficiently. However, frequent bulk data movement operations can be costly in terms of space, time, and staff resources.
With PowerExchange change data capture (CDC), you can capture only the changes that are made to a data source. PowerExchange CDC has minimal impact on the performance and availability of the source database, tables, and files. PowerExchange provides two methods of change data capture:
  • Synchronous change data capture, which occurs in real time by integrating into the transaction performing the change
  • Asynchronous change data capture, also called log-based changed data capture, which captures the changes from the source database or source relational database logs.
PowerExchange works with PowerCenter® to move bulk data and change data to a variety of data target types across an enterprise.
This manual provides reference information for customizing PowerExchange for your environment. After installing the product, review the topics on the DBMOVER configuration file parameters and product security options. Also, review any of the other topics that might pertain to your specific environment and data replication requirements.
