Example of logged data elements

Changed data log records contain many data elements as a result of a call. This topic provides an example where a third-level segment is replaced and path data is requested to be logged.

Changed data log records contain many data elements as a result of a call. Consider a situation where a third-level segment is replaced and path data is requested to be logged (Root segment is A, second-level segment is B, and the replaced segment is C). In this situation, the data elements are logged in the following order:

  1. CAPD
  2. DBD Version ID
  3. Physical concatenated key
  4. CAPD_DATA block for A
  5. Segment data for A
  6. CAPD_DATA block for B
  7. Segment data for B
  8. CAPD_DATA block for C
  9. Segment data for C
  10. CAPD_DATA block for C (before data)
  11. Before-image data for C

If path data had not been requested, the CAPD_DATA blocks and segment data elements for A and B would not be logged.
