Answer: GDG - group of dataset that are logically or chronologically related, referred by name and a relative generation number - an integer which identifies the generation of a dataset and is coded in parentheses after dataset name. The IBM Mainframe Developer Training in Chennai at ACTE is renounced the most effective training for this technology. In the mainframe system, long-term data storage was handled at the application level, with several Batch jobs being responsible for archiving, back up, and pruning.
Moving mainframe workloads to alternative platforms, including the cloud and containers, is a safe, proven, and cost efficient way to modernize business critical workloads and support future innovation, market growth, and expansion into new geographies. mainframe application is re-hosted, it can continue to function with minimal code changes and the end user remains WHITE PAPER Re-hosting in a Nutshell Retain New Application I nfr astruc tur e Discard Txn.
