Abstract
Embodiments of the disclosure are directed to methods, systems and computer program products for performing a planned workload switch. A method includes receiving a request to switch a site of an active workload and stopping one or more long running processes from submitting a new request to the active workload. The method also includes preventing a new network connection from accessing the active workload and processing one or more transactions in a queue of the active workload for a time period. Based on a determination that the queue of the active workload is not empty after the time period, the method includes aborting all remaining transactions in the queue of the active workload. The method further includes replicating all remaining committed units of work to a standby workload associated with the active workload.
