PowerExchange Navigator Overview

PowerExchange Navigator Overview

The PowerExchange Navigator is a graphical user interface (GUI) that runs on Windows.
Use the PowerExchange Navigator to define and manage PowerExchange objects, including the PowerExchange resources that are required to perform bulk data movement operations and change data capture (CDC) processing.
Run database row tests to verify that PowerExchange can access data when a bulk data movement operation or change data extraction runs. You can also use the
Database Row Test
 dialog box to issue PowerExchange Listener LISTTASK and STOPTASK commands and to generate restart tokens for data sources. Use the restart tokens to populate the PowerExchange Client for PowerCenter (PWXPC) restart token file for a PowerCenter® change data capture (CDC) session.
Use the following PowerExchange resources to complete bulk data movement operations or change data capture (CDC) processing:
  • Registration groups and capture registrations. Defines the source data for which you want PowerExchange to capture changes. Required to complete CDC processing.
  • Extraction groups and extraction maps. Defines the extraction information for data sources registered for capture. Required to complete CDC processing.
  • Data maps. Define data maps to access nonrelational data sources, such as IMS databases, VSAM files, and flat files, and to perform column-level processing for DB2 sources. For nonrelational sources, data maps are required to complete bulk data movement operations and to provide metadata for capture registrations.
    In a data map, you can manually define the layout of the data. Alternatively, you can import a copybook or an Adabas FDT, for example, to define the layout of the data.
Other PowerExchange objects that you can define are:
  • Application groups and applications. If you use ODBC connections to extract change data, defines the extraction information for data source registered for capture. PowerExchange generates an application group when you define a registration group.
    Application groups and applications are not used if you use the PowerExchange Client for PowerCenter (PWXPC) to extract change data, which is recommended.
  • Personal metadata profiles. Define a profile to test connectivity to a data source, view metadata, and preview data for relational and nonrelational data sources and targets.
