To Create the Extract Group

Note:

This configuration includes Extract data-pumps.

  1. On the source, use the ADD EXTRACT command to create a primary Extract group.
  2. On the source, use the ADD EXTTRAIL command to specify as many local trails as the number of Replicat groups that you will be creating. All trails must be associated with the primary Extract group.
  3. On the source create a data-pump Extract group.
  4. On the source, use the ADD RMTTRAIL command to specify as many remote trails as the number of Replicat groups that you will be creating. All trails must be associated with the data-pump Extract group.
  5. On the source, use the EDIT PARAMS command to create Extract parameter files, one for the primary Extract and one for the data pump, that contain the parameters required for your database environment. When configuring Extract, do the following:

    • Divide the source tables among different TABLE parameters.

    • Link each TABLE statement to a different trail. This is done by placing the TABLE statements after the EXTTRAIL or RMTTRAIL parameter that specifies the trail you want those statements to be associated with.
