A digital transaction ledger with a DNA-related parameter is provided by obtaining DNA-based data unique to a particular entity, and establishing a DNA-related ledger parameter using the DNA-based data. Further, the method includes associating the DNA-based ledger parameter with a digital transaction ledger, making the digital transaction ledger related, at least in part, to the obtained DNA-based data.

Digital transaction ledger with DNA-related ledger parameter

Provided are a computer program product, system, and method for selecting a plurality of processing systems to sort a data set. A determination is made of processing systems to perform a sort of records in a data set. The data set is divided into data subsets, each data subset comprising a portion of the records of the data set. Each of the determined processing systems of is notified of a data subset to sort. In response to receiving notification from the determined processing systems that the records in the data subsets have been sorted, the sorted data subsets are merged into a sorted data set comprising the records of the data set sorted.

Selecting a plurality of processing systems to sort a data set

Described are techniques for utilization of a disaster recovery site including a method comprising receiving a mirrored data stream at a disaster recovery site from a production site. The mirrored data stream includes a workload instruction stored in a designated location of the mirrored data stream. The workload instruction indicates an operation to perform on a set of data that is replicated between the production site and the disaster recovery site and a time indicator indicating a correct version of the set of data. The method further comprises generating a consistency point by retrieving replicated data from the disaster recovery site corresponding to the correct version of the set of data in the production site. The method further comprises performing the operation on the consistency point, generating an output, and transmitting the output to the production site.

Workload coordination on disaster recovery site

Methods that can batch process data on a remote system or disaster recovery (DR) site are disclosed herein. One method includes determining, by a processor, a first performance level for a production site based on a set of first resources for the production site and determining a second performance level for a DR site based on a set of second resources for the DR site. The method further includes allocating a portion of a workload scheduled for processing on the production site to the DR site for processing on the DR site in response to determining that a set of predetermined parameters related to the first performance level, the second performance level, or both the first performance level and the second performance level is satisfied. Apparatus, systems, and computer program products that can include, perform, and/or implement the methods are also disclosed herein.

Apparatus, systems, and methods for remote system batch processing

Described are techniques for utilization of a disaster recovery site including a method comprising receiving a mirrored data stream at a disaster recovery site from a production site. The mirrored data stream includes a workload instruction stored in a reserved record set type. The workload instruction indicates an operation to perform on a set of data that is replicated between the production site and the disaster recovery site and a time indicator indicating a correct version of the set of data. The method further comprises generating a consistency point by retrieving replicated data from the disaster recovery site corresponding to the correct version of the set of data in the production site. The method further comprises performing the operation on the consistency point, generating an output, and transmitting the output to the production site.
