Abstract

See full text

In one embodiment, a system includes a critical partitioned dataset extended (PDSE) stored to memory of the system; logic adapted for protecting the critical PDSE by creating a copy of the critical PDSE, referred to as a PDSE copy; logic adapted for providing a critical dataset redundancy (CDR) task with exclusive access to the PDSE copy; logic adapted for providing a replacement critical PDSE by redirecting corralled connections to the PDSE copy; logic adapted for protecting the replacement critical PDSE by creating a copy of the replacement critical PDSE, referred to as a replacement PDSE copy; and logic adapted for providing the CDR task with exclusive access to the replacement PDSE copy.
