Abstract

A data processing system and method of operation are disclosed. The data processing system includes a first site for processing data; a second site for processing data; and a transaction replay program configured to send a copy of data from the first site to the second site. A processor defines a maximum replication latency threshold and a reset threshold for the system, estimates a replication latency of a workload the system, switches the system to a first replication latency state when the estimated replication latency rises above the maximum replication latency and switches the system out of the first replication latency state to a second replication latency state when the estimated replication latency falls below the reset threshold.
