Group Source Processing of Multiple-Record Sequential Files

PowerExchange uses group source processing to read bulk data from sequential files with multiple record types.

PowerExchange group source processing reads data that is stored in the same physical source in a single pass. By eliminating multiple passes of the source data, group source processing enhances bulk data movement performance and reduces resource consumption on the source system.

To use group source processing, complete the following tasks:

Create a multiple-record data map for the sequential file data source.

Use the SEQ access method.

Import the data map into PowerCenter.

For PowerExchange to use group source processing, you must select the Multi-Record Datamaps
option in the Import from PowerExchange
dialog box.
