Enabling Offload Processing for CDC Sessions

Enabling Offload Processing for CDC Sessions

To use CDC offload processing, you must configure some PWX CDC connection attributes. Also, you must add the source-specific CAPI_CONNECTION statements to the DBMOVER configuration file on the PowerCenter Integration Service machine.
  1. Configure attributes for offload processing on the PWX CDC Real Time application connection for the CDC session.
    The following table describes the attributes that are required for offload processing:
    Connection Attribute
    Description
    Location
    Specifies the node name of the system on which the change data resides. This node name must match the name of a NODE statement in the dbmover.cfg configuration file on the PowerCenter Integration Service machine.
    Offload Processing
    Controls whether PowerExchange uses CDC offload processing. When offload processing is enabled, PowerExchange transfers column-level processing of the change data and any UOW Cleanser (UOWC) processing from the source system to the PowerCenter Integration Service machine.
    Options are:
    • No
      . Disables offload processing.
    • Yes
      . Enables offload processing.
    • Auto
      . PowerExchange determines whether to enable or disable offload processing.
    Default is No.
    CAPI Connection Name
    Specifies the name of the source CAPI_CONNECTION statement in the dbmover.cfg on the PowerCenter Integration Service machine.
  2. Copy the source-specific CAPI_CONNECTION statements from the DBMOVER configuration file on the source system to the dbmover.cfg configuration file on the PowerCenter Integration Service machine.
    For DB2 for i5/OS sources, copy CAPI_CONNECTION statements of the types AS4J and UOWC.
