Mike, I've used several log and publishing techniques for Business Continuance, and some of them, such as RRDF, do a great job of providing an asynchronous remote copy of the Database.
The problem I strike is that it is not synchronised with anything else, and the actual RPO and RTO for the business and applications in a disaster is anyone's guess. If I was still in customer land I would be looking for SAG to confirm that ADABAS supports Business Continuance with TrueCopy, PPRC, and SRDF; or else I would be migrating to a Database that does. Just a poll - how many ADABAS sites out there are doing Business Continuance with ADABAS Event Replicator versus Disk Remote Copy?
