Abstract
Various embodiments of systems, computer program products, and methods to provide mode switching in high availability disaster recovery (HADR) systems are described herein. In an aspect, an average commit wait time associated with replicating data from a primary database to a replication database is determined based on a previous average commit wait time and a current commit wait time. A counter is incremented when the average commit wait time is greater than or equal to the predefined maximum commit wait time. Further, a check is made to determine whether the counter is greater than or equal to a predefined threshold and whether a predefined timer associated with the counter is expired. When the counter is greater than or equal to the predefined threshold and the predefined timer is running, the primary database is switched from a synchronous mode to an asynchronous mode for replicating the data.
