Management and synchronization of batch workloads with active/active sites using proxy replication engines

A computer system for resynchronizing at least one batch job comprising a plurality of workloads executing on both a primary system and a secondary system by using at least one proxy replication engine, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• detecting a type of region switch request;
• in response to the detected type of region switch request, stopping execution of the plurality of workloads on the primary system;
• in response to stopping execution of the plurality of workloads, suspending a replication of software data stored on the primary system with a copy of the software data stored on the secondary system, and suspending a replication of hardware data stored on the primary system with a copy of the hardware data stored on the secondary system;
• utilizing the at least one proxy replication engine to determine a point-in-time (PIT) at which the execution of the plurality of workloads on the primary system is stopped, at which the replication of the software data is suspended, and at which the replication of the hardware data is suspended, wherein utilizing the at least one proxy replication engine comprises using the at least one proxy replication engine to read from at least one secondary log the hardware data comprising a plurality of batch components associated with the plurality of workloads and the point-in-time (PIT);
• switching the replication of the software data that occurs from the primary system to the secondary system to occur from the secondary system to the primary system;
• switching the replication of the hardware data that occurs from the primary system to the secondary system to occur from the secondary system to the primary system;
• synchronizing the software data and the hardware data for the plurality of workloads up to the determined point-in-time (PIT) and based on the point-in-time (PIT) associated with the plurality of batch components;
• and
• activating the execution of the plurality of workloads on the secondary system based on the determined point-in-time (PIT), the switching of the replication of both the hardware data and the software data, and the synchronization of the software data and the hardware data up to the determined point-in-time (PIT) associated with the at least one proxy engine and the plurality of batch components.
