Example of CDC Offload Processing with a DB2 for i5/OS Source

Example of CDC Offload Processing with a DB2 for i5/OS Source

In this example, you enable a CDC session with a PWX CDC Real Time connection to use offload processing for change data extraction from a DB2 for i5/OS source.
The source change data remains on i5/OS system but all column-level and UOW Cleanser (UOWC) processing is offloaded to the PowerCenter Integration Service machine.
  1. Copy the UOWC and AS4J CAPI_CONNECTION statements from the DBMOVER member in the
    datalib
    /CFG
     library on the i5/OS source system to the dbmover.cfg configuration file on the PowerCenter Integration Service machine.
    This example uses the following CAPI_CONNECTION statements: 
    CAPI_CONNECTION=(NAME=i5UOWC,TYPE=(UOWC,CAPINAME=i5_AS4J,RSTRADV=600,MEMCACHE=20480))
    CAPI_CONNECTION=(NAME=i5_AS4J,TYPE=(AS4J,JOURNAL=(JRN=PRODDATA/PRODJRN),INST=PROD,EOF=N,STOPIT=(CONT=5),LIBASUSER=Y))
  2. Stop the CDC session.
  3. Update the following attributes on the PWX CDC Real Time application connection for the CDC session:
    • For the
      Offload Processing
       attribute, select
      Yes
      .
    • For the
      CAPI Connection Name
       attribute, enter the name of the UOWC CAPI_CONNECTION statement. In this example, the name is i5UOWC.
  4. Restart the CDC session.
