Testing in a disaster recovery computer system

Abstract:

According to an aspect, a computer-implemented method includes configuring a disaster recovery computer system as a test environment of a mainframe computer system as a mirror image of a production environment, where the disaster recovery computer system is a backup of a primary production computer system. Test cases are executed in the test environment of the disaster recovery computer system. A stress and load impacts can be monitored on a plurality of computer system resources of the disaster recovery computer system based on execution of the test cases. The test environment can be disabled, and the disaster recovery computer system can be reconfigured as a production system based on a failure of the primary production computer system.
