Rather than use only a timestamp as a starting point, for DB2 (i Series/AS400), it would be very handy to be able to select a specific Journal Receiver/Journal Entry as a starting point.  When we perform source machine role swaps, starting at a specific time is not the most efficient way to make the switch (it often results in backup data being replicated).  Being able to start at a specific entry in the Journals.  The general format that works for us is:

JOURNAL LIBRARY/JOURNAL RECEIVER

JOURNAL ENTRY

Sample:

@JRNLIB/RMRCV24059

234288829998

A further option to start at the First Journal Entry is a Journal Receiver rather than a specific numbered entry would also be advantageous, but not required.
