On the sending DASD there is a 1 bit per track table of updated
tracks. When each track is sent the bit is reset. When it gets
caught up it sets a sync point.

Peter,
My experience is over a decade old with XRC, but I imagine the potential for
some form of read/write/IO pacing is the same and that it could impact
performance. Open a PMR and ask IBM.

The EXPORT needs to precede the PROC statement, but I am not sure if that is

That takes an extra copy of each DASD volume at each site though.

Maybe. I had a similar problem a few years ago, but in my case, I had a PROC
