Zero Lost Transactions (ZLT)

Zero Lost Transactions (ZLT), which is available only with the RDF/ZLT product, is a functional
capability that uses mirrored disks to guarantee that no committed transactions on the primary
system will be lost in the event of an RDF takeover by the backup system.

Monitoring RDF Entities With ASAP

ASAP (Availability Statistics and Performance) allows many different subsystem entities to be
monitored across a network of NonStop servers. The status and statistics for the entities are
collected on a single system, and are then monitored either through the ASAP command interface
or through the ASAP graphical user interface PC client.
RDF/IMP, IMPX, and ZLT are instrumented to feed state information to ASAP, thus allowing
RDF subsystems to be monitored, in an integrated way, alongside all other subsystems supported
by ASAP. The following RDF entities report state and statistical information to ASAP:
• Monitor
• Extractor
• RDFNET (optional)
• Receiver
• Purger
• Updater
