FDBR and local online change

FDBR tracks online changes through the x'70' log records.

To avoid problems if FDBR is shut down or restarted after an online change is performed, or to avoid problems under other circumstances after online change, take one or more IMS™ system checkpoints after the online change is complete and before FDBR is shut down or restarted. Doing so ensures that FDBR restarts from a checkpoint that was taken after the last online change.

For example, before you restart FDBR after an online change, issue the /CHECKPOINT command on the active system to take a simple checkpoint and verify from the DFS3804I message that the latest restart checkpoint time stamp is after the online change.
