Changed data log record

To retrieve all the data logged for a particular call, you must examine the physical log records to determine where the logical log record begins and ends. You can examine the changed data log record to view the captured data captured for a DL/I call.

For each DL/I call, there is one logical log record that comprises all the data requested for that call. However, because all the data might not fit in one log buffer, one logical log record can actually be composed of several physical log records. To retrieve all the data logged for a particular call, you must examine the physical log records to determine where the logical log record begins and ends.
